Hyperbole is an efficient, programmable hypertextual information management system. It is intended for everyday work on any GNU Emacs platform. Hyperbole allows hypertext buttons to be embedded within unstructured and structured files, mail messages and news articles. It offers intuitive keyboard and mouse-based control of information display within multiple windows. It also provides point-and-click access to Info manuals, ftp archives, and the World-Wide Web.
This is a reference manual with extensive details about Hyperbole use. If you prefer a simpler, more interactive introduction to Hyperbole, the FAST-DEMO file included in the Hyperbole distribution demonstrates many of Hyperbole’s standard facilities without the need to read through this reference manual. The FAST-DEMO is a good way to rapidly understand some of what Hyperbole can do for you. Once Hyperbole is installed, (see Setup), you can access the FAST-DEMO with the key sequence {C-h h d d}.
See Glossary, for definitions of Hyperbole terms. In some cases, terms are not precisely defined within the body of this manual since they are defined within the glossary. Be sure to reference the glossary if a term is unclear to you. Although you need not have a keen understanding of all of these terms, a quick scan of the glossary helps throughout Hyperbole use.
See Setup, for explanations of how to obtain, install, configure and load Hyperbole for use. This appendix includes information on user-level settings that you may want to modify after you understand Hyperbole’s basic operation.
See Suggestion or Bug Reporting, for instructions on how to ask a question, suggest a feature or report a bug in Hyperbole. A few commonly asked questions are answered in this manual, see Questions and Answers. If you are interested in classic articles on hypertext, see References.
See Smart Keys, for an explanation of the innovative, context-sensitive mouse and keyboard Action and Assist Keys offered by Hyperbole. See Smart Key Reference, for a complete reference on what the Action and Assist Keys do in each particular context they recognize. See Smart Key Argument Selection, for how Hyperbole speeds selection of values when prompting for arguments.
Keep in mind as you read about using Hyperbole that in many cases, it provides a number of overlapping interaction methods that support differing work styles. In such instances, you need learn only one technique that suits you.

Database vendors apply tremendous resources to help solve corporate information management problems. But the information that people deal with in their everyday worklife is seldom stored away in neatly defined database schemas. Instead it is scattered among local and remote files, e-mail messages, faxes, voice mail and web pages.
The rise of the web has demonstrated how hypertext technologies can be used to build massive organized repositories of scattered information. But assembling information for the web still remains a great challenge and the data formats of the web are too structured to deal with the wide variety of information that people process. Modern web development requires the use of many languages: HTML, JavaScript, and CSS. This in itself prevents its use as the prime means of organizing and interlinking the constant flows of daily information.
GNU Hyperbole takes a distinctly different approach. It has its own hypertext technology that can interface perfectly with web links but which are much easier to create (simply drag from the source to the destination of a link to create a new hyperlink). Hyperbole hyperbuttons can link not only to static information but can perform arbitrary actions (through the use of button types written in a single, highly interactive language, Emacs Lisp). Hyperbole adds all of this power to your written documents, e-mail, news articles, contact management, outlines, directory listings, and much more. Hyperbole works well with the very latest versions of GNU Emacs across every editing and viewing mode in Emacs. It’s core hypertext capabilities operate as a global minor mode available across most file types, unlike Org mode which is its own structured file format.

GNU Hyperbole (pronounced Ga-new Hi-per-bo-lee), or just Hyperbole, is like Markdown for hypertext. Hyperbole automatically recognizes dozens of common, pre-existing patterns in any buffer regardless of mode and can instantly activate them as hyperbuttons with a single key: email addresses, URLs, grep -n outputs, programming backtraces, sequences of Emacs keys, programming identifiers, Texinfo and Info cross-references, Org links, Markdown links and on and on. All you do is load Hyperbole and then your text comes to life with no extra effort or complex formatting.
Hyperbole includes easy-to-use, powerful hypertextual button types without the need to learn a markup language. Hyperbole’s button types are written in Lisp and can be wholly independent of the web, i.e. web links are one type of Hyperbole link, not fundamental to its link architecture. However, Hyperbole is a great assistant when editing HTML or Javascript or when browsing web pages and links.
Hyperbole comes pre-built with most of the implicit button types you will need but with a little extra effort and a few lines of code (or even just a few words), you can define your own implicit button types to recognize your specific buttons and then activate them anywhere in Emacs. You press a single key, {M-RET} by default, on any kind of Hyperbole button to activate it, so you can rely on your muscle memory and let the computer do the hard work of figuring out what to do. {C-u M-RET} shows you what any button will do in any context before you activate it, so you can always be sure of what you are doing when needed or if someone emails you a button (Hyperbole allows embedding buttons in email messages too).
Hyperbole is something to be experienced and interacted with, not understood from reading alone. It installs normally as a single Emacs package with no dependencies outside of built-in Emacs libraries, see Installation. Most of Hyperbole is a single global minor mode that you can activate and deactivate at will. And it can be uninstalled quickly as well if need be, so there is no risk in giving it a spin.
Once you have it installed, try the interactive demo with {C-h h d d}. In fact, if you have Hyperbole loaded and you use the Emacs Info reader to read this manual, you can press {M-RET} inside any of the brace delimited series of keys you see in this document and Hyperbole will execute them on-the-fly (easy keyboard-macro style buttons in any text).
Hyperbole can dramatically increase your productivity and greatly reduce the number of keyboard/mouse keys you’ll need to work efficiently.
Hyperbole consists of five parts.
There are three categories of buttons:
may be added to documents with a simple drag between windows, no markup language needed. With two windows on screen, an explicit link button can be created at point in the current buffer linking to the position in the other window’s buffer by pressing {C-h h e l}.
are patterns automatically recognized within existing text that perform actions, e.g. bug#24568 displays the bug status information for that Emacs bug number, without the need for any additional markup. Implicit link buttons can be added to documents with a simple drag between windows too.
Or from the keyboard, With two windows on screen, an implicit link button can be created at point in the current buffer linking to the position in the other window’s buffer by pressing {C-h h i l}. Use {M-1 C-h h i l} instead to be prompted for a name for the implicit button.
are buttons that are activated by name from anywhere within Emacs. They may be either explicit or named implicit buttons. They are the named buttons stored in the a user’s personal button file, directly editable from the minibuffer menu with {C-h h b p}.
With two windows on screen, a global explicit link button can be created at point in the current buffer linking to the position in the other window’s buffer by pressing {C-h h g l}. Use {C-u C-h h g l} instead to create a named global implicit button.
Buttons are activated by pressing {M-RET} on them, clicking them with a dedicated mouse button, or by referencing them by name (global buttons that can be activated regardless of what is on screen). Users create and activate Hyperbole buttons; see Buttons. Emacs Lisp programmers can develop new button types and actions. See Creating Types.
Hyperbole includes two special Smart Keys, the Action Key and the Assist Key, that perform an extensive array of context-sensitive operations across emacs usage, including activating and showing help for Hyperbole buttons. In many popular Emacs modes, they allow you to perform common, sometimes complex operations without having to use a different key for each operation. Just press a Smart Key and the right thing happens. The mouse versions of these keys additionally allow for drag actions. We call these the Action Mouse and Action Assist keys or buttons. See Smart Keys.
a powerful, hierarchical contact manager which anyone can use, is also included. It is easy to learn since it introduces only a few new mechanisms and has a menu interface, which may be operated from the keyboard or the mouse. It may also be used for full-text searching over any record-based information in any number of Org, Markdown, Koutline or Emacs Outline files. Hyperbole buttons may be embedded in any records. See HyRolo.
the fastest, easiest-to-use window and frame control available for GNU Emacs. With just a few keystrokes, you can shift from increasing a window’s height by 5 lines to moving a frame by 220 pixels or immediately moving it to a screen corner. Text in each window or frame may be enlarged or shrunk (zoomed) for easy viewing, plus many other features; this allows Hyperbole to quickly control the way information is presented on-screen. See HyControl.
an advanced outliner with multi-level autonumbering and permanent identifiers attached to each outline node for use as hypertext link anchors, per node properties and flexible view specifications that can be included in links or used interactively. See Koutliner.
a set of programming libraries for system developers who want to integrate Hyperbole with another user interface or as a back-end to a distinct system. (All of Hyperbole is written in Emacs Lisp for ease of modification. It has been engineered for real-world usage and is well structured). See Developing with Hyperbole.
Hyperbole may be used simply for browsing through documents pre-configured with Hyperbole buttons, in which case, you can safely ignore most of the information in this manual. Jump right into the Hyperbole fast demonstration by typing {C-h h d d}, assuming Hyperbole has been installed at your site. If you need to install Hyperbole, see Setup, for Hyperbole installation and configuration information. The demo offers a much less technical introduction to Hyperbole by supplying good examples of use.
You likely will want to do more than browse with Hyperbole, e.g. create your own buttons. The standard Hyperbole button editing user interface is Emacs-based, so a basic familiarity with the Emacs editing model is useful. The material covered in the Emacs tutorial, normally bound to {C-h t}, is more than sufficient as background. See Glossary in the GNU Emacs Manual, if some emacs-related terms are unfamiliar to you.
A Hyperbole user works with chunks of information that need to be organized, interlinked, and processed. Such chunks can be hyperbuttons, address book contacts, items in an outline, or even database query results. Hyperbole does not enforce any particular hypertext or information management model, but instead allows you to organize your information in large or small chunks as you see fit. The Hyperbole outliner organizes information into hierarchies which may also contain links to external information sources. See Koutliner.
Some of Hyperbole’s most significant features are:
Typical Hyperbole applications include:
Hyperlinks provide a variety of views into an information space. A search facility locates hyperbuttons in context and permits quick selection.
Cross-references may be embedded within documentation and code. Existing documentation may be augmented with point-and-click interfaces to link code with associated design documents, or to permit direct access to the definition of identifiers by selecting their names within code or other documents.
The Hyperbole outliner (see Koutliner) is an effective tool for capturing ideas and then quickly reorganizing them in a meaningful way. Links to related ideas are easy to create so the need to copy and paste information is greatly reduced.
Tutorials with buttons can show students how things work while explaining the concepts, e.g. an introduction to the commands available on a computer system. This technique can be much more effective than written documentation alone.
Programs that manage archives from incoming information streams may be supplemented by having them add topic-based buttons that link to the archive holdings. Users can then search and create their own links to archive entries.

Once Hyperbole has been installed for use at your site, loaded into your
Emacs session and activated with (hyperbole-mode 1), it is ready
for use. You will see a Hyperbole menu on your menubar and Hypb in
your modeline.

You can invoke Hyperbole’s commands in one of three ways:
{C-h h} enables Hyperbole if it has been disabled and displays a Hyperbole menu in the minibuffer for quick keyboard or mouse-based selection. Select an item from this menu by typing the item’s first capital letter. Use {Q} (note this is capitalized) to quit from the minibuffer menu while leaving Hyperbole enabled. Use {X} (note this is capitalized) to quit from the minibuffer menu and disable Hyperbole’s minor mode.
Use {C-h h d d} for an interactive demonstration of standard Hyperbole button capabilities.
Type {C-h h k e} for an interactive demonstration of the Koutliner, Hyperbole’s multi-level autonumbered hypertextual outliner.
To try out HyControl, Hyperbole’s interactive frame and window control system, use {C-h h s w} for window control or {C-h h s f} for frame control. Pressing {t} switches between window and frame control once in HyControl. Hyperbole also binds {C-c \} for quick access to HyControl’s window control menu if it was not already bound prior to Hyperbole’s initialization.
Videos demonstrating Hyperbole’s features are listed at https://gnu.org/s/hyperbole.
The above are the best interactive ways to learn about Hyperbole.

The Hyperbole Manual is a reference manual, not a simple introduction. It is included in the man/ subdirectory of the Hyperbole package directory in four forms:
man/hyperbole.info - online Info browser version man/hyperbole.html - web HTML version man/hyperbole.pdf - printable version man/hyperbole.texi - source form
The Hyperbole package installation places the Info version of this
manual where needed and adds an entry for Hyperbole into the Info
directory under the Emacs category. {C-h h d i} will let you
browse the manual. Then use {s} to search for anything
throughout the manual. For web browsing, point your browser
to ${hyperb:dir}/man/hyperbole.html, wherever the
Hyperbole package directory is on your system; often this
is: ~/.emacs.d/elpa/hyperbole-${hyperb:version}/.
Previous: Documentation, Up: Usage [Contents][Index]
When Hyperbole’s code is first loaded and initialized, hyperbole-init-hook
is run. When hyperbole-mode is enabled, hyperbole-mode-hook and
hyperbole-mode-on-hook are run. When hyperbole-mode is disabled,
hyperbole-mode-hook and hyperbole-mode-off-hook are run.
If you prefer a different key to activate Hyperbole, you can bind it as part
of any setting of hyperbole-init-hook within your personal
~/.emacs file. For example, (add-hook
'hyperbole-init-hook (lambda () (global-set-key "\C-ch"
'hyperbole--enable-mode) (global-set-key "\C-hh" 'view-hello-file))); then
restart Emacs.
When active, Hyperbole offers two special Smart Keys, the Action Key and the Assist Key, that perform an extensive array of context-sensitive operations across emacs usage. In many Emacs modes, they allow you to perform common, sometimes complex operations without having to use a different key for each operation. Just press a Smart Key and the right thing happens. This chapter explains typical uses of the Smart Keys. See Smart Key Reference, for complete descriptions of their behavior in all contexts.

Next: Smart Key Operations, Previous: Smart Keys, Up: Smart Keys [Contents][Index]
With hyperbole-mode enabled, {M-RET} is the Action Key
and {C-u M-RET} is the Assist Key. These keys allow
context-sensitive operation from any keyboard.
Mouse configuration of the Smart Keys is automatic for GNU Emacs under Mac OS X, the X Window System and MS Windows, assuming your emacs program has been built with support for any of these window systems.
The Action Mouse Key is bound to your shift-middle mouse key (or shift-left on a 2-button mouse). The Assist Mouse Key is bound to your shift-right mouse key, assuming Hyperbole is run under an external window system. These keys support Drag Actions, see Smart Mouse Keys, as well as the standard Smart Key presses.
If you set the variable, hmouse-middle-flag, to ‘t’ before
loading Hyperbole, then you may also use the middle mouse key as the Action
Key. If you want both the middle mouse key as the Action Key and the
right mouse key as the Assist Key for ease of use, then within your
personal ~/.emacs file, add: (add-hook 'hyperbole-init-hook
'hmouse-add-unshifted-smart-keys) and then restart Emacs.
If you prefer other Smart Key bindings, simply bind the commands
action-key and assist-key to keyboard keys.
Hyperbole binds {M-RET} to the command hkey-either;
this provides a single key binding for both Smart Key commands; a prefix
argument, such as {C-u}, then invokes assist-key actions.
You may also bind action-mouse-key and assist-mouse-key to
other mouse keys, though you won’t be able to execute mouse drag actions with
such key bindings. See Smart Mouse Key Drags, and see Keyboard Drags.
To permanently change any of these key bindings, use:
(add-hook 'hyperbole-init-hook (lambda () (hkey-set-key <KEY> '<CMD>),
for example, (hkey-set-key "\M-'" 'hkey-either).
Next: Smart Key Argument Selection, Previous: Smart Key Bindings, Up: Smart Keys [Contents][Index]
The Action Key generally selects entities, creates links and activates buttons. The Assist Key generally provides help, such as reporting on a button’s attributes, or serves a complementary function to whatever the Action Key does within a context.
The Hyperbole Doc/SmartKeys menu entry, {C-h h d s}, displays a summary of what the Smart Keys do in all of their different contexts. Alternatively, a click of the Assist Mouse Key in the right corner of a window modeline (within the rightmost 3 characters) toggles between displaying this summary and hiding it. Reference this summary whenever you need it.
The following table is the same summary. Much of the browsing power of Hyperbole comes from the use of the Smart Keys, so spend some time practicing how to use them. Study what modeline clicks and window drag actions do as these will give you a lot of power without much effort. This table may appear daunting at first, but as you practice and notice that the Smart Keys do just a few context-sensitive things per editor mode, you will find it easy to just press or point and click and let Hyperbole do the right thing in each context.

See Smart Key Reference, for extensive reference documentation on the Smart Keys.
Note how the last line in the table explains that the default behavior of
the Smart Keys in an unknown context is to report an error. You can change
these behaviors by setting two variables. See the documentation
for the variables action-key-default-function and
assist-key-default-function for information on how to customize
the behavior of the Smart Keys within default contexts.
When you use a mouse and you want to find out what either of the Smart Keys does within a context, depress the one you want to check on and hold it down, then press the other and release as you please. A help buffer will pop up explaining the action that will be performed in that context and attributes of the button, if any. A press of either Smart Key at the end of that help buffer will restore your display to its configuration prior to invoking help.
On the keyboard, {C-h A} displays this same context-sensitive help for the Action Key while {C-u C-h A} displays the help for the Assist Key. Note that {C-h a} performs a function unrelated to Hyperbole, so you must press the shift key when you type the A character.
Next: Smart Key Debugging, Previous: Smart Key Operations, Up: Smart Keys [Contents][Index]
A prime design criterion of Hyperbole’s user interface is that you should be able to see what an operation will do before using it. The Assist Key typically shows you what a button or minibuffer menu item will do before you activate it. Hyperbole also displays the result of directly selecting an argument value with the Action Key, to provide feedback as to whether the correct item has been selected. A second press/click is necessary before an argument is accepted and processed.
Many Hyperbole commands prompt you for arguments. The standard
Hyperbole user interface has an extensive core of argument types that
it recognizes. Whenever Hyperbole is prompting you for an argument,
it knows the type that it needs and provides some error checking to
help you get it right. More importantly, it allows you to press the
Action Key within an entity that you want to use as an argument.
Hyperbole will copy the appropriate thing to the minibuffer as the
argument. If you press (click with a mouse) the Action Key on the
same thing again, e.g. within a list of possible completions,
Hyperbole exits the minibuffer and uses the current argument. Thus, a
double click registers a desired argument. Double-quoted strings,
pathnames, mail messages, Info nodes, dired listings, buffers,
numbers, completion items and so forth are all recognized at
appropriate times. All of the argument types mentioned in the
documentation for the Emacs Lisp interactive function are
recognized. Experiment a little and you will quickly get used to this
direct selection technique.
Wherever possible, standard Emacs completion is offered, as described in Completion in the GNU Emacs Manual. Remember to use {?} to see what your possibilities for an argument are if completions are not automatically shown to you. Once you have a list of possible completions on screen, press the Action Key twice on any item to enter it as the argument. If you are using the Vertico completion library with completions displayed in the minibuffer, selection of completions works the same as if they were displayed in a separate buffer as in standard Emacs.
Within the minibuffer itself, the Smart Keys are also context-sensitive. A press of the Action Key at the end of the argument line tries to accept the argument and when successful, exits the minibuffer. A press of the Assist Key at the end of the argument line displays matching completions for times when they are not automatically displayed or need updating. A press of the Action or Assist Key on part of the argument, deletes from point to the end of the line, expanding the set of available completions and redisplaying them.

Typically, {C-h A} and {C-u C-h A} which show Action and Assist Key help for the current context, are sufficient for seeing how the Smart Keys behave no matter where they are used.
However, if a Smart Key ever behaves differently than you think it should or if you want to test how the Smart Keys respond in a new context, then the Smart Key debugging flag may be of use. You toggle it on and off with {C-h h c d} (minibuffer menu Cust/Debug-Toggle). Once enabled, this displays a message in the minibuffer each time the Action or Assist Key is released, showing the context of the press and its associated action, so you can see exactly what is happening whenever you use a Smart Key. These messages are all prefaced with “(HyDebug)” and logged to the “*Messages*” buffer for later viewing.
If you do find a problem with the Smart Keys and want to report a bug, use {C-h h m r} to compose an email message to the bug-hyperbole list. Hyperbole will automatically include all of the “(HyDebug)” messages from your current emacs session into your email. Similarly, when you compose an email to the hyperbole-users mailing list with {C-h h m c}, these messages are also included.

Hyperbole has some radically cool ways to select regions of structured text or source code and to copy or move them between buffers with a single mouse drag or two key presses. A great deal of smarts are built-in so that it does the right thing most of the time; many other attempts at similar behavior such as thing.el fail to deal with many file format complexities.
We use the term things to refer to structured entities that Hyperbole can select. These include: delimited pairs of (), {}, <>, [] and quote marks, source code functions, source code comments and matching tag pairs in HTML and SGML modes. Delimited things are those things that contain a selectable delimiter such as an opening parenthesis.
The best way to mark a delimited thing is to move your cursor to the starting delimiter of the thing and then press the Action Key. Typically, you will see the thing highlight. You can then operate upon it as you would any Emacs region. In many cases, you can do the same thing upon the closing delimiter, but this is not as reliable. An Action Key press on the start of an HTML, XML, or SGML tag pair marks the entire region span of the pair. If you use the Assist Key instead, it will mark and kill (delete) the thing.
Even better are Smart Mouse Key thing drags which let you copy or move delimited things in one operation without having to select a region. To copy, simply drag with the Action Key from a thing’s opening delimiter and release somewhere outside of the thing, either within the same window or within another window. The thing will be copied to the point of release. If you want to move a thing, simply perform the same drag but with the Assist Mouse Key. Ensure that you do not move any explicit buttons from one buffer to another as that does not work.
Hyperbole also binds two convenience keys for working with things.
The first such key is {C-c RET} hui-select-thing which
selects bigger and bigger syntactic regions with each successive use.
Double or triple clicks of the Selection Key (left mouse key) do the same
thing. The first press selects a region based upon the character at point.
For example, with point over an opening or closing grouping character, such
as { or }, the whole grouping is selected, e.g. a C function. When on an
_ or - within a programming language identifier name, the whole name is
selected. The type of selection is displayed in the minibuffer as
feedback. When using a language in which indentation determines nesting
level like Python, a double click on the first alpha character of a line,
such as an if statement, selects the current clause (until the next line at
the same or lesser indentation). Use {C-g} to unmark the region when
done. Use, hui-select-thing-with-mouse if you want to bind this to
a different mouse key to use single clicks instead of double clicks.
This key defers to any currently active major-mode which also
binds it.
The second convenience key is bound in HTML/XML/SGML/web
modes. {C-c .} hui-select-goto-matching-tag jumps between
the opening and closing tag of a pair. It moves point to the start of
the tag paired with the closest tag that point is within or which it
precedes. A second press moves point to the matching tag of the pair,
allowing you to quickly jump back and forth between opening and
closing tags.
This key defers to any currently active major-mode which also
binds it.

Smart Mouse Key clicks on a window’s modeline offer many powerful browsing features, including directory editing (dired), user manual browsing, and window, buffer and frame selection. Generally, only Hyperbole-specific modeline actions are discussed herein.
Action Key clicks on the first (usually blank) character of the modeline bury the current buffer in the buffer list and display the next buffer in the list. Assist Key clicks do the reverse and unbury the bottom buffer.
A similar effect can be achieved with the standard Emacs mouse 1 (left) and 3 (right) buttons on the Buffer ID element of modeline to cycle through previous and next buffers, respectively. This may be easier to use since you can click anywhere on the buffer identifier.
On the left part of the modeline is the buffer identification, generally the name of the buffer in use. An Action Key click on that switches the window to edit the buffer’s directory using dired. Then Action Key clicks on directory items in the dired buffer display the items selected in other windows. An Action Key drag from an item to another window displays the item in that window.
An Action Key click on the first line in a dired buffer which contains the current directory path, specifically on any ancestor part of the path (the part to the left of the click point), starts another dired session on the ancestor directory. Click at the end of this line or on the last line to end the dired session (bury its buffer).
If you use the Treemacs file viewer Emacs package, you can configure Hyperbole to use this instead of Dired when you click on a modeline buffer id.
Since this is a customization option, it may be changed permanently like so.
Use {M-x customize-set-variable RET action-key-modeline-buffer-id-function RET}.
Change the value to smart-treemacs-modeline. Then press RET. To change it back
to Hyperbole’s default, use the value, dired-jump.
An Action Mouse Key click in a blank area of a window modeline (away from left and right edges) toggles between displaying and hiding a list of all buffers. Once displayed, an Action Key click on a buffer item will display it in another window. You can drag items to specific windows for display as well.
Alternatively, you may (1) display the buffer menu, (2) use its {m}
command to mark buffers, and (3) use the Hyperbole {@} command to
display the marked buffers in a grid of popup windows whose number of
rows and columns you specify at the prompt or via a prefix argument.
This also works in ibuffer-menu and dired modes.
See HyControl.
An Assist Key click in the blank area of the modeline displays a quick access menu of display-oriented commands. You can jump to buffers categorized by major mode, jump to windows by buffer name, or to frames by name. Manage your windows and frames quickly with this menu as well. As always with Hyperbole, just try it and you’ll begin to wonder how you lived without it before.
A click of the Action Mouse Key in the right corner of a window modeline (within the rightmost 3 characters) displays or hides the GNU Info Manual Browser, giving you quick point and click access to an amazing wealth of documentation, since the Action Key also browses through these manuals and follows their hyperlinked cross-references. A click of the Assist Key in the same location displays or hides the Smart Key summary, as noted earlier.
Hyperbole modeline mouse click actions are controlled by the two functions,
action-key-modeline and assist-key-modeline. If you know
a little Emacs Lisp you can change these to do whatever you like. When a
Smart Key press is on a blank part of a modeline but not at the left or
right, the function given by one of these two variables is
executed: action-key-modeline-function or
assist-key-modeline-function. By default, the Action Key toggles
between displaying and hiding the buffer menu. If you like the more
advanced features of Ibuffer Mode, you can change the buffer menu to
use that with the following in your Emacs initialization file:
(setq action-key-modeline-function #'hmouse-context-ibuffer-menu).
To set it back to the default use:
(setq action-key-modeline-function #'hmouse-context-menu).
The default assist-key-modeline-function is to pop up a menu of
convenient screen commands that lets you select buffers grouped by
major mode, use HyControl, or jump to specific windows, window
configurations or frames.
Since these are customization options, they may be change permanently like so. Use {M-x customize-set-variable RET assist-key-modeline-function RET}. Change the value to your desired command. Then press RET.

As mentioned in the section on Thing Selection, Hyperbole Smart Mouse Key drag actions can be quite useful. This section summarizes other drag contexts and actions; for complete documentation, see Smart Mouse Keys.

Next: Saving and Restoring Window Configurations, Previous: Smart Mouse Key Drags, Up: Smart Mouse Key Drags [Contents][Index]
Horizontal and vertical drags of the Smart Mouse Keys are used to split and delete Emacs windows.
An Action Mouse Key horizontal drag of five or more characters in either direction within a single window creates a new window by splitting the current window into two windows, one atop the other. An Action Mouse Key vertical drag in either direction splits the current window into two side-by-side windows. A horizontal or vertical drag of the Assist Mouse Key within a single window, deletes that window.
If you split windows many times and then delete a number of the windows, you’ll be left with windows of differing heights. Use {C-x +} to re-balance the sizes of the remaining windows, so they are fairly even.
Next: Resizing Windows, Previous: Creating and Deleting Windows, Up: Smart Mouse Key Drags [Contents][Index]
A window configuration consists of the set of windows within a single Emacs frame. This includes their locations, buffers, and the scrolled positions of their buffers.
Hyperbole allows you to save and restore window configurations with simple diagonal mouse drags within a single window. A diagonal drag in any direction of the Action Key saves the current window configuration to a ring of window configurations, just like the Emacs text kill ring. See Kill Ring in the Emacs Manual. Each diagonal drag in any direction of the Assist Key restores a prior saved window configuration from the ring. Window configurations are restored in reverse order of the way they were saved. Since a ring is circular, after the oldest element is restored, the newest element will again be restored and so on.
Next: Moving Frames, Previous: Saving and Restoring Window Configurations, Up: Smart Mouse Key Drags [Contents][Index]
Emacs windows may be resized by dragging their window separators (modelines or vertical side lines) within a frame. Simply depress either Smart Mouse Key on a non-bottommost modeline or near a window side, hold it down while you drag to a new location and then release. The window separator will move to the location of release. Basically, just drag the window separator to where you want it. Drags from a blank area of a modeline show visible feedback as the window is resized.
Next: Dragging Buffers, Previous: Resizing Windows, Up: Smart Mouse Key Drags [Contents][Index]
Drags of either Smart Key from a bottommost modeline can be configured to drag Emacs frames to new locations on screen. To configure all existing and future frames for such dragging, use:
(modify-all-frames-parameters '((drag-with-mode-line . t))).
To configure just the selected frame for such dragging, use:
(set-frame-parameter nil 'drag-with-mode-line t).
on each frame you would like to drag.
Then drag with either Smart Key from a bottommost modeline within a frame to move the frame on screen with live feedback, as if you were dragging from the titlebar. If you use a click-to-focus window manager, click on the desired frame first and then depress to drag.
Previous: Moving Frames, Up: Smart Mouse Key Drags [Contents][Index]
Smart Mouse Key drags let you display buffers and windows however you want them. Dired, Treemacs and buffer-menu items as well as Hyperbole button referents may be displayed in specific locations with drags. Below we explore these drag actions.

Next: Displaying Buffers, Previous: Dragging Buffers, Up: Dragging Buffers [Contents][Index]
Swapping buffer locations is quick and easy with Hyperbole. Simply drag the Assist Mouse Key (not the Action Key) from the open area of one window’s modeline to the text area of another. This works across frames as well.
If you have precisely two windows in an Emacs frame, you can swap their buffers from the keyboard. Use this Hyperbole minibuffer menu key sequence involving the tilde key to swap the buffers and quit from the Hyperbole minibuffer menu: {C-h h s w ~ Q}. Similarly, if you have two single window frames, you can swap buffers between them with {C-h h s f ~ Q}.
Next: Cloning Windows, Previous: Swapping Buffers, Up: Dragging Buffers [Contents][Index]
What if you want to display the same buffer in another window and not swap buffers? Depress the Action Mouse Key in the open area of the modeline of the source window and drag to the text area of the destination window. Voila, the buffer appears in the new location as well as the old one.
If you want a new window where you release (so the original destination window’s buffer stays onscreen), just drag to the release window’s modeline; that window will be split before the buffer is displayed.
Next: Displaying Items, Previous: Displaying Buffers, Up: Dragging Buffers [Contents][Index]
To clone a window with its buffer to a new frame, simply drag the Action Mouse Key from the window to outside of Emacs and release the key. A new frame will be created, selected and sized according to the original window. Do the same thing with the Assist Mouse Key and the original window will be deleted as well, unless it is the only window in that frame.
Next: Keyboard Drags, Previous: Cloning Windows, Up: Dragging Buffers [Contents][Index]
You can also drag items to other windows with the Action or Assist Mouse Keys in Dired, Buffer Menu, Ibuffer and Treemacs listing buffers, rather than the buffers themselves. Dragging Hyperbole buttons to display their referents in another window works too.
Drag with the Action or Assist Mouse Key and the selected item’s referent will be displayed in any Emacs window in which you release. Drag outside Emacs and it will be displayed in a new frame. To display the last item you want within the listing window itself, press and release the Action Key on that item after dragging your other items to their respective windows. Remember that you can emulate these drags from the keyboard when needed, see Keyboard Drags.
So now you can put a bunch of buffers and files on your screen wherever you like. Typically, a brief visual pulse is shown first at the source item and then in the destination window, to help you see that the transfer has been made. An Assist Key drag will move the the item list buffer to the destination (swapping buffers), just as it does with other buffers.
Previous: Displaying Items, Up: Dragging Buffers [Contents][Index]
If you run Emacs under a window system and there is no prior key binding
on {M-o} when you load Hyperbole, then many Smart Key drags can be
emulated from the keyboard. To do so, press {M-o}, the
hkey-operate command, at the button source location, move to the
link destination, e.g. with {C-x o}, and then press {M-o}
again. This simulates a depress and release of the Action Key.
{C-u M-o} emulates drags of the Assist Key. This will not work when
Hyperbole is run from a dumb terminal Emacs session since drag actions
are not supported without a window system.
For even faster keyboard-based display of items and drag emulations,
use the Emacs package ace-window
(see https://elpa.gnu.org/packages/ace-window.html).
The ace-window package assigns short letter IDs to each Emacs window and lets you jump to or operate upon a specific window by giving its ID. Hyperbole can add commands to ace-window that replace the two-step drag emulation key described above with a single key sequence that does not require moving to the drag target window since it is specified by ID as part of the command.
To enable this feature, in your Emacs initialization file after Hyperbole
is initialized, if you do not have a key bound for ace-window,
then call: (hkey-ace-window-setup \"\M-o\") to bind it to
{M-o}, replacing Hyperbole’s default hkey-operate command
there (because ace-window can emulate the drags performed by
hkey-operate). If you already have a key bound for
ace-window, then just ensure it is initialized by calling
(hkey-ace-window-setup) without a key argument.
After setup, the leftmost character or two of each window’s modeline will show the ID to type to use that window as the drag destination. Then whenever point is on an item you want displayed in another window, use {M-o i <id-of-window-to-display-item-in>} and watch the magic happen. If you want to display multiple items in different windows, instead use the {M-o t <id-of-window-to-display-item-in>} key sequence to throw the item to the window. To replace the selected window’s buffer with that of another window, use {M-o r <id-of-window-displaying-desired-buffer>}. To instead swap the selected window’s buffer with that of another window, use {M-o m <id-of-window-to-swap-with>}.
And finally, to create a new, unnamed implicit link in the
selected window that refers to the location in the other window, use
{M-o w <referent-window-id>}. This executes hui:ibut-link-directly
which determines the link type by using the referent context. To create
a named implicit link button in the selected window, use
{M-1 M-o w <window>}. It prompts for the name and then links to
the referent window location. If you highlight a region
before invoking this, Hyperbole will use that as the name for the
implicit button.
To create an explicit button the same way, use {C-u M-o w
<window-id>}. This executes hui:ebut-link-directly, prompts for
any needed arguments, determines the link type by using the referent
context and then creates the explicit button. If you highlight a region
before invoking this, Hyperbole will use that as the name for the
explicit button.
You can also throw the active (highlighted) region of text to another
window. Simply activate a region and then use {M-o
t <window-id>}. If you don’t use region highlighting,
i.e. transient-mark-mode, then use {C-u M-o
t <window-id>} for the same effect. The buffer in the target window
must differ from the one in the source window. With no region active,
this command throws the source buffer to the target window.
In summary:
insert listing item at point into <window>; if not on a listing item, trigger an error
swap the buffers in the selected window and <window>
replace the selected (current) window’s buffer with that of <window>
throw region, listing item at point, or current buffer to <window>
window link, create a new unnamed implicit button in the selected (current) window, linking to point in the referent <window>.
window link, create a new named implicit button in the selected (current) window, linking to point in the referent <window>. Use region, if any, as the button name.
window link, create a new explicit button in the selected (current) window, linking to point in the referent <window>. Use region, if any, as the button name.

This chapter explains use of Hyperbole buttons. There are several kinds of Hyperbole buttons: buttons that are created one at a time and stored in files (explicit buttons); buttons that can be activated by name anytime (global buttons); and buttons defined by textual patterns where one definition can create an infinite number of buttons (implicit buttons).
Hyperbole buttons are embedded within textual documents; they may be created, modified, moved or deleted. Each button performs a specific action, such as linking to a file or executing a shell command.
There are three categories of Hyperbole buttons:
created by Hyperbole, accessible from within a single document;
created by Hyperbole, specific to each user, and accessible anywhere within a user’s network of documents;
created and managed by other programs or embedded within the structure of a document, accessible from within a single document. Hyperbole recognizes implicit buttons by contextual patterns given in their type specifications (explained later).
Explicit Hyperbole buttons may be embedded within any type of text file. Implicit buttons may appear only within document contexts allowed by their types, which may limit the kinds of documents or the locations within those documents at which such buttons may be found. All global buttons for a user are stored in a single location and are activated by typing their names, rather than by direct selection, the means used to activate explicit and implicit buttons.
To summarize:
Button Category Active Within Activation Means Managed By ======================================================================== Explicit a single document direct selection Hyperbole Global any document typing its name Hyperbole Implicit a matching context direct selection other tools
A click on a Hyperbole button may activate it or describe its actions, depending on which mouse key is used. Buttons may also be activated from a keyboard. (In fact, many Hyperbole operations, including menu usage, may be performed from any standard character terminal interface, so you need not be anchored to a desktop all day). See Smart Keys. There is also a key that shows you how a button will behave before you activate it, see Smart Key Operations.

Hyperbole creates and manages explicit buttons which perform specific actions when activated (typically through a button press). They look like this ‘<(fake button)>’. They are quickly recognizable, yet relatively non-distracting as you scan the text in which they are embedded. The text between the ‘<(’ and ‘)>’ delimiters is called the button label or button name. Spacing between words within a button label is irrelevant to Hyperbole. Button labels may wrap across several lines without causing a problem; just be sure to select the first line of the button to activate it.
Explicit buttons may be added to any editable buffer including temporary buffers without any attached files (such buttons will last only the length of a single Emacs session). For source code files, simply place Hyperbole explicit buttons within comments. Buttons that you use for quick navigation to websites or other things you do often should be added to your personal button file. See Button Files.
Explicit buttons may be freely moved about within the buffer in which they are created. (No present support exists for moving buttons between buffers). A single button may also appear multiple times within the same buffer; simply copy the button label with its delimiters to a new location if you need another copy of it.
For details on how to create, activate, delete or edit explicit buttons, see Utilizing Explicit Buttons.
Each explicit button is assigned an action type that determines the
actions it performs. Hyperbole includes its own set of useful action
types but any named, interactive Emacs Lisp command may be used. For
example, Link action types connect buttons to particular types
of referents, the targets of their links. Link action type
names all begin with link-. Link action button referents are
displayed when such buttons are activated with a press or a click.
See Action Types, for a list of Hyperbole action types, including
link types.
Hyperbole does not manage referent data; this is left to the applications that generate the data. This means that Hyperbole provides in-place linking and does not require reformatting data to integrate it with Hyperbole.
Hyperbole stores the button data that gives an explicit button its behavior, separately from the button label, in a file named .hypb (_hypb under MS Windows) within the same directory as the file in which the button is created. Thus, all files in the same directory share a common button data file. Button data is comprised of individual button attribute values. A user never sees this data in its raw form but may see a formatted version by asking for help on a button.
Next: Implicit Buttons, Previous: Explicit Buttons, Up: Buttons [Contents][Index]
Sometimes it is useful to activate buttons without regard to the information with which you are working. In such instances, you use global buttons, which are buttons that may be activated or otherwise operated upon by typing their names/labels when they are prompted for, rather than selecting the buttons within a buffer. In contrast, activation of explicit buttons depends upon the information on your screen since they are accessible only from within their particular buffers.
If you want a permanent link to a file section that you can follow at
any time, you can use a global button. Or what about an Emacs keyboard
macro that you use frequently? Create a global button with an action type
of exec-kbd-macro button and an easy to type name. Then you can
activate it whenever the need arises.
Global buttons are managed with the Hyperbole Gbut/ menu accessed with {C-h h g}. The Create item, {C-h h g c}, prompts for a global button name, an action type, and the action’s associated arguments, such as a file to which to link. It then creates the button. To activate the button, use the Act menu item, {C-h h g a}. Type the button’s name, press {RET}, and then Hyperbole prompts you for its action type and associated arguments. {C-h h g e} to edit an existing global button. To remove a button, use the Delete menu item, {C-h h g d}; see Deletion.
To create a global button that links to point in one of your Emacs windows, use the Link menu item, {C-h h g l}.
By default this will create a global explicit link button. Give it a prefix argument to create a global implicit link button.
With a single window visible on-screen or a single window within your current frame, this will prompt you for a button name or label (temporarily showing you your global/personal button file) and then will insert a button that links to the current point within that window.
If you have exactly two Emacs windows in your current frame or exactly two windows visible across two Emacs frames, then the link referent will be to the point in the other, non-selected window.
With more than two windows on screen, Hyperbole will prompt you to choose the referent window and its associated point to which to link. If the Ace Window package is installed and active, this will be used to choose the window via keyboard; otherwise, you will be prompted to select it by mouse.
Global buttons are actually explicit buttons stored at the end of your personal button file, see Button Files. You can always go into that file and activate, edit or annotate these buttons with comments.
Emacs has a built-in feature similar to Global Buttons called
Bookmarks. Bookmarks store places in files or link to URLs, so they
are more limited than Hyperbole’s global buttons and cannot utilize
all of Hyperbole’s capabilities for performing actions. Hyperbole has
an action type, link-to-bookmark, for using an Emacs bookmark
as a Hyperbole button referent. See Bookmarks in the Emacs
Manual, for details on bookmarks.
Next: Button Files, Previous: Global Buttons, Up: Buttons [Contents][Index]
Hyperbole can recognize and activate implicit buttons within documents that require no special markup, e.g. pathnames or URLs, and many other types. For example, an Action Key press on a web URL will display its link in a browser, regardless of the format of the document. Similarly, an Action Key press on an email address starts composing mail to that address.
Implicit buttons are identified by implicit button type contextual
pattern matchers that identify appropriate textual patterns at point.
An implicit button type utilizes Emacs Lisp to identify a
pattern or state that when matched triggers an action
associated with the implicit button type. The action is specified by
either a Hyperbole action type (see Action Types) or an Emacs Lisp
command. Implicit button types may use the same action types that
explicit buttons use. As an example, the pathname implicit button
type matches to any existing local filename or directory name and its
action type, link-to-file, displays the associated file or
directory, typically in another window. An explicit button could do
the same thing but has to be created manually, rather than recognized
as part of the buffer text.
Implicit buttons are managed with the Hyperbole Ibut/ menu accessed with {C-h h i}. The Create item, {C-h h i c}, prompts for an implicit button name (default is any selected region), an action type, and the action’s associated arguments. It then creates the button at point. Use this to create a button with any implicit button type, not just links.
Alternatively, to create an implicit link button to something displayed within an Emacs window (the referent), simply drag with the Action Mouse Key depressed from an editable source window to another window with the desired link referent and then release. The drag must start outside of a draggable item, see Displaying Items. Hyperbole will either automatically select the button type based on the referent context or will prompt you to select from one of a few possible link types.
If you have exactly two Emacs windows in your current frame or exactly two windows visible across two Emacs frames, this is even easier. Simply use the Link menu item, {C-h h i l}, to create a new unnamed implicit link button or to edit the one at point. {C-u C-h h i l} will additionally prompt to add a name or rename the button at point. With more than two windows, Hyperbole will prompt you to choose the referent window and its associated point to which to link. If the Ace Window package is installed and active, this will be used to choose the window via keyboard; otherwise, you will be prompted to select it by mouse.
To activate an implicit button with point on its name or button text, use the Act menu item, {C-h h i a} or press the Action Key. You can use {C-h h i e} to edit an implicit button (or simply edit it manually). If you want to add a name to an existing implicit button without one, use {C-h h i n} to name it. Rename an existing named implicit button with {C-h h i r}.
Unlike explicit buttons, implicit buttons have no individual button data other than their text and optional labels. You use implicit button types which include boolean expressions (predicates) that match to both the label and the context required of any button of the type. Each time a Smart Key is pressed at a location, Hyperbole evaluates the predicates from the list of implicit button types and the first one that evaluates true is selected and its associated action is triggered.
All of this happens transparently and is easy to use once you try it. The Hyperbole Smart Keys offer additional extensive context-sensitive point-and-click type behavior beyond implicit button types. See Smart Key Operations.
Individual implicit buttons may be labeled/named, allowing activation by name or use as a link target by other buttons. Such names are highlighted similarly to explicit button names. Here is a pathname button with a label of ’My Emacs Files’:
<[My Emacs Files]>: "~/.emacs.d"
The name is delimited by ‘<[’ and ‘]>’ and can be followed by any number of :, - or = separator characters, including none.

Below is a list of standard implicit button types in the order in which Hyperbole tries to match to the types when looking for an implicit button (decreasing priority order). {C-h h i t RET} provides similar information. See the Hyperbole file, hibtypes.el, for examples of how to define implicit button types (in the file, they are listed in reverse order, increasing in priority).
smart-orgsmart-org is not an actual implicit button type, just an Elisp function,
but it behaves similarly, so it is documented here.
Hyperbole recognizes Org mode constructs in any of these modes:
org-mode, org-agenda-mode, outshine-mode
or poporg-mode. (See the function hsys-org-mode-p).
Hyperbole does quite a few things for Org mode users. When the Action Key is pressed:
org-ctrl-c-ctrl-c.
org-meta-return.
When the Assist Key is pressed, it behaves just like the Action Key except in these contexts:
To disable Hyperbole support within Org major and minor modes, set
the custom option hsys-org-enable-smart-keys to nil. Then in
Org modes, the Action Key will simply invoke org-meta-return.
{C-h h c o} (minibuffer menu Cust/Org-M-RET) will interactively customize
this setting.
The following table summarizes the effect of this option setting.
|--------------+-------------------+------------------+----------+------------------| | This Setting | Smart Key Context | Hyperbole Button | Org Link | Fallback Command | |--------------+-------------------+------------------+----------+------------------| | buttons | Ignore | Activate | Activate | org-meta-return | | nil | Ignore | Ignore | Ignore | org-meta-return | | t | Activate | Activate | Activate | None | |--------------+-------------------+------------------+----------+------------------|
doc-idDisplay a document from a local document library given its id. Ids must be
delimited by doc-id-start and doc-id-end and must match the
function given by doc-id-p. (Note that this implicit button type is
not installed by default. You must manually configure it and load it from
the file, ${hyperb:dir}/hib-doc-id.el). See the commentary
at the top of that file for more information.
completionInsert the completion at point (from a completions buffer) into the minibuffer or the other window.
actionThe Action Button type. At point, activate any of: an Elisp variable, a Hyperbole action-type, or an Elisp function call surrounded by <> rather than (). If an Elisp variable, display a message showing its value.
hyp-sourceTurn source location entries following an ‘@loc>’ line in Hyperbole reports into buttons that jump to the associated location. For example, {C-u C-h h d d C-h h e h o} summarizes the properties of the explicit buttons in the ${hyperb:dir}/DEMO file and each button in that report buffer behaves the same as the corresponding button in the original ${hyperb:dir}/DEMO file.
hyp-addressWithin a mail or Usenet news composer window, make a Hyperbole
support/discussion e-mail address insert Hyperbole environment and
version information. This is useful when sending mail to a Hyperbole
discussion mail list. See also the documentation for
actypes::hyp-config. For example, a click of an Action Mouse
Key on <hyperbole-users@gnu.org> in a mail composer window
would activate this implicit button type.
Info-nodeMake a "(filename)nodename" button display the associated Info node. Also make a "(filename)itemname" button display the associated Info index item. Examples are "(hyperbole)Implicit Buttons" and “(hyperbole)C-c /”.
gnus-push-buttonActivate GNUS-specific article push-buttons, e.g. for hiding signatures. GNUS is a news and mail reader.
texinfo-refDisplay Texinfo, Info node or help associated with Texinfo node, menu item, @xref, @pxref, @ref, @code, @findex, @var or @vindex at point. If point is within the braces of a cross-reference, the associated Info node is shown. If point is to the left of the braces but after the @ symbol and the reference is to a node within the current Texinfo file, then the Texinfo node is shown.
For @code, @findex, @var and @vindex references, the associated documentation string is displayed.
patch-msgJump to the source code associated with output from the ‘patch’ program. Patch applies diffs to source code.
elisp-compiler-msgJump to source code for definition associated with an Emacs Lisp byte-compiler error message or ERT test output line. Works when activated anywhere within such a line.
debugger-sourceJump to the source line associated with a debugger stack frame or breakpoint line. This works with gdb, dbx, and xdb. Such lines are recognized in any buffer.
hib-python-tracebackTest for and jump to line referenced in Python pdb, traceback, or pytype error.
grep-msgJump to the line associated with a grep or compilation error message. Messages are recognized in any buffer.
hyrolo-stuck-msgJump to the position where a HyRolo search has become stuck from the error. Such errors are recognized in any buffer.
ripgrep-msgJump to a line associated with a ripgrep (rg) line numbered msg. Ripgrep outputs each pathname once, followed by all matching lines in that pathname. Messages are recognized in any buffer (other than a helm completion buffer).
ipython-stack-frameJump to the line associated with an ipython stack frame line numbered msg. ipython outputs each pathname once followed by all matching lines in that pathname. Messages are recognized in any buffer (other than a helm completion buffer).
pathname-line-and-columnMake a valid pathname:line-num[:column-num] pattern display the path at line-num and optional column-num. Also works for remote pathnames. May also contain hash-style link references with the following format: <path>[#<link-anchor>]:<line-num>[:<column-num>].
link-to-ibut <ilink>At point, activate a link to an implicit button within the current buffer. This executes the linked to implicit button’s action in the context of the current buffer.
Recognizes the format ’<ilink:’ button_label [’:’ button_file_path] ’>’, where button_file_path is given only when the link is to another file, e.g. <ilink: my series of keys: ${hyperb:dir}/HYPB>.
link-to-gbut <glink>At point, activate a link to a global button. This executes the linked to global button’s action in the context of the current buffer.
Recognizes the format ’<glink:’ button_label ’>’, e.g. <glink: open todos>.
link-to-ebut <elink>At point, activate a link to an explicit button within the current buffer. This executes the linked to explicit button’s action in the context of the current buffer.
Recognizes the format ’<elink:’ button_label [’:’ button_file_path] ’>’, where : button_file_path is given only when the link is to another file, e.g. <elink: project-list: ~/projs>."
klinkFollow a link delimited by <> to a koutline cell.
See the documentation for actypes::link-to-kotl for valid link
specifiers.
man-aproposMake man apropos entries (from ‘man -k’) display associated man pages when selected.
rfcRetrieve and display an Internet Request for Comments (RFC) standards
document referenced at point. The following formats are recognized:
RFC822, rfc-822, and RFC 822. The hpath:rfc variable specifies
the location from which to retrieve RFCs via HTTP.
kbd-keyExecute a key series (series of key sequences) around point,
delimited by curly braces, {}. Key series should be in
human readable form, e.g. {C-x C-b}. Formats such as {^x^b}
will not be recognized. The string within (kbd "string") also
acts as a key series button.
Any key sequence must be a string of one of the following:
debbugs-gnu-modeDebbugs is a client-server issue tracker used by GNU free software
projects, including Hyperbole, to manage issues and maintain threads
of discussion around them. You issue queries to a Debbugs server and
it returns a listing entry for each matching issue. When on a GNU
Debbugs listing entry in debbugs-gnu-mode, an Action Key press
displays the discussion of the selected issue; an Assist Key press
pretty prints the status of the issue to a window below the listing
window.
debbugs-gnu-queryDisplay the results of a Debbugs query based on a bug reference string around point. This works in most types of buffers. If the query includes a single id number, it displays the original message submission for that id and allows browsing of the followup discussion. The following buffer text formats are accepted (with point prior to any attribute):
bug#id-number, bug# id-number, bug #id-number or bug id-number bug?attr1=val1&attr2=val2&attr3=val3 bug#id-number?attr1=val1&attr2=val2&attr3=val3
Note that issue or debbugs may also be used in place of bug. See the documentation at the top of the hib-debbugs.el file for detailed query format information.
dir-summaryDetect filename buttons in files named "MANIFEST" or "DIR". Display selected files. Each filename must be at the beginning of the line and must be followed by one or more spaces and then another non-space, non-parenthesis, non-brace character.
text-tocJump to the text file section referenced by a table of contents (toc) entry at point. This works in any text derived major mode buffer with a ‘Table of Contents’ or ‘Contents’ label on a line by itself (it may begin with an asterisk), preceding the table of contents. Each TOC entry must begin with some whitespace followed by one or more asterisk characters. Each section header linked to by the toc must start with one or more asterisk characters at the very beginning of the line. TOCs in Internet RFCs work as well. For example, display this RFC, <link-to-rfc 822>, and Action Key press on any TOC line to jump to the associated section. Or try it in the Hyperbole DEMO file.
cscopeJump to a C/C++ source line associated with a Cscope C analyzer output line. The cscope.el Lisp library available from the Emacs package manager must be loaded and the open source cscope program available from http://cscope.sf.net must be installed for this button type to do anything.
etagsJump to the source line associated with an etags file entry in a TAGS buffer. If on a tag entry line, jump to the source line for the tag. If on a pathname line or line preceding it, jump to the associated file.
ctagsJump to the source line associated with a ctags file entry in any buffer. Ctags files are used by old editors like vi to lookup identifiers. Emacs uses the newer, more flexible Etags format.
id-cflowExpand or collapse C call trees and jump to code definitions.
Requires cross-reference tables built by the external cxref
program.
rfc-tocSummarize contents of an Internet rfc from anywhere within an rfc buffer. Each line of the summary may be selected to jump to the associated section.
markdown-internal-linkDisplay any in-file Markdown link referent. Pathnames and urls are handled elsewhere.
git-commit-referenceDisplay the changeset for a git commit reference, e.g. commit a55e21, typically
produced by git log. Hyperbole also includes two commands, hypb:fgrep-git-log
and hypb:grep-git-log to list git commit references whose changesets contain
either the string (fgrep) or regular expression (grep) given. Then an Action Key
press displays the associated changeset.
social-referenceDisplay the web page associated with a social media hashtag or username reference at point.
Reference format is:
[facebook|instagram|twitter]?[#@]<hashtag-or-username> or [fb|in|tw]?[#@]<hashtag-or-username>
For example, ‘fb@someuser’ displays the home page for facebook user
‘someuser’ and ‘in#hashtag’ displays photos with the hashtag
‘hashtag’. The first part of the label for a button of this type
is the social media service name. The service name defaults to the
value of hibtypes-social-default-service (default value of
“twitter”) when not given, so #hashtag would be the same as
twitter#hashtag.
annot-bibDisplay annotated bibliography entries defined within the same buffer as the reference. References must be delimited by square brackets, must begin with a word constituent character, and must not be in buffers whose names begin with a ‘ ’ or ‘*’ character.
mail-addressIf on an e-mail address in a specific buffer type, compose mail to that
address in another window. Applies to any major mode descended from those
in hypb:mail-address-mode-list, the HyRolo match buffer, any buffer
attached to a file included in hyrolo-file-list, or any buffer with
mail or rolo (case-insensitive) within its name. If
hypb:mail-address-mode-list is set to ‘nil’, this button type is
active in all buffers.
www-urlWhen not in an Emacs web browser buffer, follow any non-ftp URL (link) at point.
The variable, browse-url-browser-function, may be used to customize
which URL browser is called. Terse URLs which lack a protocol prefix,
like www.gnu.org, are also recognized.
pathnameMake a valid pathname display the path entry. Also works for
delimited and non-delimited remote pathnames, Texinfo @file{}
entries, and hash-style link references to HTML, XML, SGML, Markdown
or Emacs outline headings, shell script comments, and MSWindows paths
(see ${hyperb:dir}/DEMO#POSIX and MSWindows Paths for
details). Emacs Lisp library files (filenames without any directory
component that end in .el and .elc) are located using
the load-path directory list.
The pathname may contain references to Emacs Lisp variables or shell
environment variables using the syntax, \"${variable-name}\".
See Link Variable Substitution, for how this handled. The constant,
hpath:variable-regexp, matches to this pattern within pathnames.
See the function documentation for hpath:at-p for possible
delimiters. See the variable documentation for hpath:suffixes for
suffixes that are added to or removed from the pathname when searching
for a valid match. See the function documentation for hpath:find
for special file display options.
If instead is a PATH-style variable name, .e.g. MANPATH, will
prompt with completion for one of the paths and will then display that.
If it is the colon or semicolon-separated string of paths value from a
PATH-style variable, the path at point is displayed; empty paths,
e.g. :: represent the current directory, .. Must have at
least four paths within the variable value for this to work.
hyperbole-run-test-definitionWith an Action Key press on the name in the first line of an ert test def, evaluate and run the ERT test. With an Assist Key press instead, edebug the test and step through it.
hyperbole-run-testsRecognize Action Buttons of the form <hyperbole-run-tests
test-selector> which when activated run Hyperbole tests using the ERT
framework. The test-selector argument is as described in
ert-select-tests.
hyperbole-run-testRecognize Action Buttons of the form <hyperbole-run-test
test-name> which when activated run individual Hyperbole tests, each
given by the <test-name> argument, an unquoted name.
Previous: Implicit Button Types, Up: Implicit Buttons [Contents][Index]
Explicit buttons all use the same syntax and store their action data in a file separate from the button source file. Implicit buttons have no external data but use a unique syntax per implicit button type to recognize the action to run.
For times when you need a cross between the two, with a universal button syntax and all button data stored in the button source file, there are action buttons.
Action Buttons are a form of implicit buttons that can execute any existing action types, Emacs Lisp functions, Emacs Regression Tests (ERT tests) or display the values of Emacs Lisp variables and constants. Such buttons are delimited by angle brackets, < >, and come in four types:
These begin with an action type name (from the list displayed by {C-h h d t a RET}) and are followed by any needed arguments to form the action, e.g.
<link-to-file-line "${hyperb:dir}/hact.el" 40>
These are similar to action type invocations but begin with an Emacs Lisp function name rather than an action type name, e.g.
<find-file-other-window "/tmp">
Generally, such functions are invoked for their side-effects and their return value is silently ignored. But if a function is a boolean predicate whose name ends in ‘-p’, then the result is displayed in the minibuffer.
Each of these consists solely of the name of an ERT test defined with
ert-deftest and surrounded by angle brackets, e.g.
<hbut-tests-ibut-insert-kbd-key>
The above example runs a Hyperbole regression test when activated and shows the pass/fail result in a pop-up buffer.
These consist of an Emacs Lisp variable name only. They display messages with their variable name and value, e.g.
<fill-column>
If there is a function binding with the same name as the variable you
wish to display, to prevent interpretation as a function call
action button, precede the name with a $, e.g.
<$fill-column>
With action buttons you need not remember any special syntax for each type of implicit button. You can freely embed them in any type of text and use the Action and Assist keys on them as you do with any other type of implicit button.
An action button is recognized only if the first name within the angle brackets is an existing action type or Emacs Lisp symbol. Otherwise, other implicit button types will be tested and may activate instead.
To activate a frequently used action button by name independent of your current buffer, simply add it to your global button file and precede it with a label {C-h h i l}. Then invoke it by label name with: {C-h h g a}.
Next: Action Types, Previous: Implicit Buttons, Up: Buttons [Contents][Index]
It is often convenient to create files filled with buttons as a means of navigating distributed information pools or for other purposes. These files can also serve as useful roadmaps that guide a user through both unfamiliar and highly familiar information spaces. Files that are created specifically for this purpose are called Hyperbole button files.
The Hyperbole menu system provides quick access to two types of these
button files: personal and directory-specific, through the ButFile menu.
(The variable, hbmap:filename, contains the base name of these
button files. Its standard value is HYPB.)
A personal button file may serve as a user’s own roadmap to frequently
used resources, like a personal home page. Selection of the
ButFile/PersonalFile menu item, {C-h h b p}, displays this file for
editing. The default personal button file is stored within the
directory given by the hbmap:dir-user variable whose standard
value is ~/.hyperb. The default Hyperbole configuration also
appends all global buttons to the end of this file, one per line, as
they are created. So you can edit or annotate them within the file.
A directory-specific button file may exist for each file system directory. Such files are useful for explaining the contents of directories and pointing readers to particular highlights within the directories. Selection of the ButFile/DirFile menu item, {C-h h b d}, displays the button file for the current directory; this provides an easy means of updating this file when working on a file within the same directory. If you want to view some other directory-specific button file, simply use the normal Emacs file finding commands.
If you want group and site-specific button files, simply place links to such files at the top of your personal button file and do so for your colleagues. This provides a flexible means of connecting to such resources.
Next: Button Type Precedence, Previous: Button Files, Up: Buttons [Contents][Index]
Action types are Emacs Lisp commands that specify Hyperbole
button behaviors. Hyperbole includes a useful set of action types
defined within their own namespace and created with the defact
macro. See the Hyperbole file, hactypes.el, for examples of
how to define your own Hyperbole action types.
Each action type may be used by any category of button: global, explicit, or implicit. The arguments needed by an action type are prompted for at button creation time or in the case of an implicit button, computed when the button is activated. During button activation, the arguments are fed to the action type’s body to achieve the desired result. This body is called the button action.
Hyperbole handles all of this processing transparently. As a user, all you need know is the set of action types that you can work with when creating explicit or global buttons.
Hyperbole action types in alphabetical order are:
annot-bibFollow an internal reference KEY within an annotated bibliography, delimiters = [ ].
completionInsert a completion at point into the minibuffer or a buffer. Unless point is at the end of buffer or if a completion has already been inserted, in which case, delete the completions window.

yt-searchSearch Youtube for SEARCH-TERM.
yt-urlReturn url to play VIDEO-ID from point specified by optional START-TIME-STRING. Return nil if START-TIME-STRING is given but is invalid. If not given, START-TIME-STRING is set to "0s" representing the beginning of the video.
START-TIME-STRING is a colon-separated hours:minutes:seconds string, e.g. 1:2:44 (1 hour, two minutes, 45 seconds), where the hours and minutes are optional.
Action types create a convenient way of specifying button behavior
without the need to know how to program. Expert users who are familiar
with Emacs Lisp, however, may find that they often want to tailor button
actions in a variety of ways not easily captured within a type system.
In such cases, hui:ebut-prompt-for-action should be set to
‘t’. This will cause Hyperbole to prompt for an action to override
the button’s action type at each explicit button creation. For those cases
where the action type is sufficient, a ‘nil’ value should be
entered for the action. An action may be any Lisp form that Emacs
Lisp can evaluate.
Next: Utilizing Explicit Buttons, Previous: Action Types, Up: Buttons [Contents][Index]
Explicit buttons always take precedence over implicit buttons. Thus, if a button selection is made which falls within both an explicit and implicit button, only the explicit button will be selected. Explicit button labels are not allowed to overlap; Hyperbole’s behavior in such cases is undefined.
If there is no explicit button at point during a selection request, then each implicit button type predicate is tested in turn until one returns non-nil or all are exhausted. Since two implicit button types may have overlapping domains, those contexts in which their predicates are true, only the first matching type is used. The type predicates are tested in reverse order of definition, i.e. most recently entered types are tested first, so that personal types defined after standard system types take precedence. It is important to keep this order in mind when defining new implicit button types. By making match predicates as specific as possible, one can minimize any overlapping implicit button domains.
Once a type name is defined, its precedence relative to other types remains the same even if its body is redefined, as long as its name is not changed. This allows incremental modifications to types without any worry of altering their precedences. See Creating Types, for information on how to develop or modify types.

Next: Renaming, Previous: Utilizing Explicit Buttons, Up: Utilizing Explicit Buttons [Contents][Index]
Creating explicit buttons is fun and easy. You can always try them out immediately after creating them or can utilize the Assist Key to verify what buttons do.
If you want to create an explicit link button to somewhere within an Emacs window, then simply drag with the Assist Mouse Key from an editable buffer (outside of a draggable item) to the target buffer. Note, the same Action Mouse Key drag creates an implicit button instead.
Alternatively, the Hyperbole minibuffer menu item, Ebut/Create, will create any type of explicit button, but requires a few steps.
The next two subsections examine explicit button creation and modification in detail.
| • By Menu: | ||
| • By Link: | Creation Via Buffer Link | |
| • By Dragging: | Creation Via Assist Key Drags |
Explicit buttons are managed with the Hyperbole Ebut/ menu accessed with {C-h h e}. The Create item, {C-h h e c}, creates any type of explicit button. It prompts for an explicit button label (default is any selected region), an action type, and the action’s associated arguments. It then creates the button at point and surrounds the label with <(explicit button delimiters)> like so, to indicate success.
You can use the direct selection techniques mentioned in Smart Key Argument Selection, to select any completion-based arguments. If you do not mark a region before invoking the button create command, you will be prompted for both a label and a target buffer for the button and the delimited label text will be inserted into the target buffer after a successful button creation.
If a previous button with the same label exists in the same buffer, Hyperbole will add an instance number to the label when it adds the delimiters so that the name is unique. Thus, you don’t have to worry about accidental button name conflicts. If you want the same button to appear in multiple places within the buffer, just enter the label again and delimit it yourself or copy and paste the button with its delimiters. Hyperbole will interpret all occurrences of the same delimited label within a buffer as the same button.
Next: By Dragging, Previous: By Menu, Up: Creation [Contents][Index]
If you have exactly two Emacs windows in your current frame or exactly two windows visible across two Emacs frames, you can quickly create explicit link buttons from your current point (source) to the point in the other window (referent). Simply use the Link menu item, {C-h h e l}, to create a new explicit link button or to rename the one at point. Hyperbole will either use the selected region as the new button label or will prompt you for it. It will then automatically choose the link type based on the referent location and will either update the button at point or create a new one.
With more than two windows on screen, Hyperbole will prompt you to choose the referent window and its associated point to which to link. If the Ace Window package is installed and active, this will be used to choose the window via keyboard; otherwise, you will be prompted to select it by mouse.
Alternatively, to create an explicit link button to a referent displayed within an Emacs window, simply drag with the Assist (not the Action) Mouse Key depressed from an editable source window to another window with the desired link referent and then release. The drag must start outside of a draggable item, see Displaying Items. Hyperbole will either automatically select the button type based on the referent context or will prompt you to select from one of a few possible link types.
In detail, you should split your current Emacs frame into two windows: one which contains the point at which you want a button to be inserted and another which shows the point to which you want to link. Depress the Assist Mouse Key at the source point for the button (anywhere but on a paired delimiter such as double quotes or parentheses). Then drag to the other window and release the Assist Mouse Key at the start point of the link referent. The process becomes quite simple with a little practice. (See Creation Via Menus, for a more detailed explanation of the explicit button creation process).
If a region was selected prior to the start of the drag, it is used as the button label; otherwise, you are prompted for the label. Hyperbole uses the link referent context to determine the type of link to make. If there are a few different types of links which are applicable from the context, you will be prompted with a list of the types. Simply use the Action Key or the first capital letter of the link type to select one of the type names to finish the link creation. Hyperbole will then insert explicit button delimiters around the button label and will display a message in the minibuffer indicating the button label, its action/link type, and any arguments, notably the thing to which it links.
The following table shows the type of link that will be created based upon the referent context in which the Action Key is released.
Referent Context Link Type ---------------------------------------------------- Org Roam or Org Id link-to-org-id Global Button link-to-gbut Explicit Button link-to-ebut Implicit Button link-to-ibut Bookmarks List link-to-bookmark Info Index Item link-to-Info-index-item Info Node link-to-Info-node Texinfo Node link-to-texinfo-node Mail Reader Message link-to-mail Directory Name link-to-directory Filename link-to-file Koutline Cell link-to-kcell Outline Heading link-to-string-match Buffer attached to File link-to-file Buffer without File link-to-buffer-tmp
Next: Deletion, Previous: Creation, Up: Utilizing Explicit Buttons [Contents][Index]
Once an explicit button has been created, its label text must be treated specially. Any inter-word spacing within the label may be freely changed, as may happen when a paragraph is refilled, but a special command must be invoked to rename it.
The rename command operates in two different ways. If point is within a button label when it is invoked, it will tell you to edit the button label and then to invoke the rename command again after the edit. The second invocation will actually rename the button. If instead the command is originally invoked outside of any explicit button, it will prompt for the button label to replace and the label to replace it with and then will perform the renaming. All occurrences of the same button in the buffer will be renamed.
The rename command may be invoked from the Hyperbole menu via
Ebut/Rename. Hyperbole does not bind this command to a key by default.
{C-h w hui:ebut-rename RET} will show what if any key is bound
within your Emacs. Bind it within your ~/.emacs file with:
(hkey-set-key "\C-cr" 'hui:ebut-rename), for example.
Next: Editing, Previous: Renaming, Up: Utilizing Explicit Buttons [Contents][Index]
Ebut/Delete works similarly to the Rename command but deletes the selected button. The button’s delimiters are removed to confirm the deletion. If the delete command is invoked with a prefix argument, then both the button label and the delimiters are removed as confirmation.
Presently there is no way to recover a deleted button; it must
be recreated. Therefore, the hui:hbut-delete-confirm-flag variable
is true by default, causing Hyperbole to require confirmation before
interactively deleting explicit buttons. Set it to ‘nil’ if you
prefer no confirmation.
Next: Searching and Summarizing, Previous: Deletion, Up: Utilizing Explicit Buttons [Contents][Index]
Ebut/Edit prompts you with each of the elements from the button’s attributes list and allows you to edit each in turn.
There is a quicker way to edit explicit link buttons, however. Simply drag with the Action Mouse Key from within the button label to a link destination in a different window, just as you would when creating a new button with a mouse drag. Remember that drags may also be emulated from the keyboard. See Creation.
Next: Buttons in Mail, Previous: Editing, Up: Utilizing Explicit Buttons [Contents][Index]
The Ebut/Help menu may be used to summarize either a single explicit button or all such buttons within a buffer. The buttons summarized may then be activated directly from the summary.
Ebut/Help/BufferButs summarizes the explicit buttons in the order in which they appear in the buffer. Ebut/Help/CurrentBut summarizes only the button at point. Ebut/Help/OrderedButs summarizes the buttons in alphabetical order. All of these summary commands eliminate duplicate occurrences of buttons from their help displays.
Ebut/Search prompts for a search pattern and searches across all the locations in which you have previously created explicit buttons. It asks you whether to match to any part of a button label or to whole labels only. It then displays a list of button matches with a single line of surrounding context from their sources. Any button in the match list may be activated as usual. An Action Key press on the surrounding context jumps to the associated source line. A press on the filename preceding the matches jumps to the file without selecting a particular line.
There are presently no user-level facilities for globally locating buttons created by others or for searching on particular button attributes.
Next: Buttons in News, Previous: Searching and Summarizing, Up: Utilizing Explicit Buttons [Contents][Index]
Hyperbole supports embedding buttons within electronic mail messages composed in Emacs. An enhanced mail reader may then be used to activate the buttons within messages just like any other buttons. Because this involves complex changes to mail support functions, this feature is disabled by default. Use the Cust/Msg-Toggle-Ebuts minibuffer menu item to enable it.
Hyperbole supports the following mail readers: Rmail (see Reading Mail with Rmail in the GNU Emacs Manual), VM (see Introduction in the VM Manual) and MH-e. Button inclusion and activation within USENET news articles is also supported in the same fashion via the Gnus news reader if available at your site (see The Gnus Newsreader in the Gnus Manual). (The hmail.el file defines a generalized interface that can be used to hook in other mail or news readers if the necessary interface functions are written.)
All explicit buttons to be mailed must be created within the outgoing
message buffer. There is no present support for including text from
other buffers or files which contain explicit buttons, except for the
ability to yank the contents of a message being replied to, together
with all of its buttons, via the (mail-yank-original) command
bound to {C-c C-y}. From a user’s perspective, buttons are
created in precisely the same way as in any other buffer. They also
appear just like any other buttons to both the message sender and the
reader who uses the Hyperbole enhanced readers. Button operation may be
tested any time before a message is sent. A person who does not use
Hyperbole enhanced mail readers can still send messages with embedded
buttons since mail composing is independent of any mail reader
choice.
Hyperbole buttons embedded within received mail messages behave as do any other buttons. The mail does not contain any of the action type definitions used by the buttons, so the receiver must have these or she will receive an error when she activates the buttons. Buttons which appear in message Subject lines are copied to summary buffers whenever such summaries are generated. Thus, they may be activated from either the message or the summary buffers.
Nothing bad will happen if a mail message with explicit buttons is sent to a non-Hyperbole user. The user will simply see the text of the message followed by a series of lines of button data at its end. Hyperbole mail users never see this data in its raw form.
In order to alert readers of your mail messages that you can handle
Hyperbole mail buttons, you can set the variable, smail:comment,
to an expression that automatically inserts a comment into each
outgoing message to announce this fact. See its documentation for
technical details. By default, no comment is added. To have a
comment line added to your outgoing message, add the following to
to your ~/.emacs file before the point at which you load
Hyperbole.
(setq smail:comment
(format "Comments: GNU Hyperbole mail buttons accepted, v%s.\n"
hyperb:version))
This will produce the following line in outgoing messages:
Comments: GNU Hyperbole mail buttons accepted, vX.X.X.
where the X’s indicate your Hyperbole version number. You can cut this out of particular messages before you send them when need be.
A final mail-related facility provided by Hyperbole is the ability to
save a pointer to a received mail message by creating an explicit button
with a link-to-mail action type. When prompted for the mail
message to link to, if you press the Action Key within the message, the
appropriate link parameters will be copied to the argument prompt, as
described in Smart Key Argument Selection.
Previous: Buttons in Mail, Up: Utilizing Explicit Buttons [Contents][Index]
Explicit buttons may be embedded within outgoing USENET news articles and may be activated from within the Gnus news reader. Because this involves complex changes to news support functions, this feature is disabled by default. Use the Cust/Msg-Toggle-Ebuts minibuffer menu item to enable it (enabling it for mail also enables it for news and vice versa).
Once enabled, all Hyperbole support should work just as it does when reading or sending mail. See Buttons in Mail. When reading news, buttons which appear in message Subject lines may be activated within the Gnus subject buffer as well as the article buffer. When posting news, the *post-news* buffer is used for outgoing news articles rather than a mail-related buffer.
Remember that the articles you post do not contain the action type definitions used by the buttons, so the receiver must have these or she will receive an error when she activates the buttons. You should also keep in mind that most USENET readers will not be using Hyperbole, so if they receive a news article containing explicit buttons, they will wonder what the button data at the end of the message is. You should therefore limit distribution of such messages. For example, if most people at your site read news with Gnus and use Hyperbole, it would be reasonable to embed buttons in postings to local newsgroups.
In order to alert readers of your postings that they may send you personal replies with embedded Hyperbole buttons, the system inserts into news postings the same comment that is included within mail messages, if enabled. See Buttons in Mail, for details and an explanation of how to turn this feature on.
Pulldown and popup menus are available to invoke Hyperbole commands,
including those from the HyRolo and the Koutliner. These menus operate
like any other application menus and are fairly self-explanatory. Use
the Remove-This-Menu command on the Hyperbole menubar menu to
get rid of the menu if you do not need it. Invoking Hyperbole from
the keyboard, as explained below, will add the menu back to the
menubar. Here is the Hyperbole Menubar Menu and its Find submenu.
The Hyperbole popup menu, hyperbole-popup-menu, replicates the
Hyperbole menubar menu. It can be bound to a mouse key but is not
bound to one by default. It can also be assigned as the default
Action or Assist Key action to use when no matching context is found.
See Smart Key - Default Context, for details.
The rest of this section discusses only the specialized minibuffer menus which appear in the minibuffer window and work with all emacs versions on all display devices. They provide similar capabilities to those of the Hyperbole menubar but additionally allow for fast menu item selection via the keyboard or mouse. When used with the keyboard, they provide command access similar to key bindings. In fact, any menu item can be bound to a global key sequence. See Binding Minibuffer Menu Items.
The top-level Hyperbole minibuffer menu is invoked from a key given in your hyperbole.el file (by default, {C-h h}) or with a click of the Action Mouse Key in the minibuffer when it is inactive. It should look like this:
Hy> Act Butfile/ Cust/ Doc/ Ebut/ Find/ Gbut/ Hist Ibut/ Kotl/ Msg/ Rolo/ Screen/ Win/
A menu item can be selected in a number of ways:
A prefix argument given to one of the movement commands, moves by that number of items within the menu. A press of the Assist Key on an item displays help for the item, including the action that it performs. "/" at the end of an item name indicates that it brings up a submenu.
While a menu is active, to re-activate the top-level Hyperbole menu, use {C-t} or press the Action Key while on the menu prefix (before the ‘>’ character). This allows you to browse the submenus and then return to the top menu.
You can reload the Hyperbole minibuffer menus and Smart Key handlers to reflect any recent edits when on the top-level Hyperbole menu by pressing {RET} or the Action Key on the menu name (first item that ends with ’>’). This will also quit from the menu.
You can quit from the minibuffer menus without selecting an item by using {Q}, or by pressing {RET} or {M-RET} when at the end of a menu. {C-g} aborts from the minibuffer whether you are at a menu prompt or any other Hyperbole prompt. {X} both quits the menus and disables the Hyperbole global minor mode; {C-h h} restores the menus and re-enables Hyperbole minor mode.
The top-level Hyperbole minibuffer menu items serve the following purposes:
Activate button at point or if there is no button at point, prompt for a labeled explicit or implicit button from the current buffer to activate.
Easy access to a directory-specific or personal file of buttons. HYPB is the name of the directory-specific button file and ~/.hyperb/HYPB is the personal file of global buttons. These are good places to begin experimenting with button creation.
Hyperbole option customization. This includes whether ftp and www
URLs are recognized by the find-file commands, where Hyperbole
link referents are displayed, where URLs are displayed, where web
search results are displayed, whether date stamps are added to rolo
entries, and whether to use proportional or windowful scrolling when a
Smart Key is pressed at the end of a line.
See Customization.
The ‘KeyBindings/’ submenu allows individual changes to each keyboard key that Hyperbole binds for its commands, notably the Action Key. See Smart Key Bindings, for more information.
See Hyperbole Key Bindings, for complete descriptions of Hyperbole’s key bindings and how to manage them.
All explicit button commands. The window-system-based Hyperbole menu includes an activation menu item for each explicit button found in the current buffer.
Hyperbole documentation quick access. This menu contains an About item which describes Hyperbole; a Concepts item that discusses how Hyperbole features all interrelate; a Demo item which demonstrates a number of interactive Hyperbole features; a New item that details new Hyperbole features, as well as a WhyUse item with use cases. It also contains the Types/ submenu for documentation on Hyperbole implicit button and action types.
Buffer and file line finding commands and web searching. This menu brings together many existing line finding commands that are difficult to recall quickly when needed, simplifying finding and then jumping to matching lines by using the Action Key. It includes commands for filtering a buffer to just those lines that either match or do not match a regular expression. It also includes a submenu for quick access to popular web search engines.
Below are each of the commands on the Find menu.
hypb:rgrep-command to change the
grep command or options.
mdfind command); on UNIX, it uses
the locate command. Within the resulting
*Locate* buffer, Find/Grep-Files will find matching lines
within only these paths (files and directories).
Hyperbole binds the key {C-c /} for quick
access to this menu, if it is not already bound
prior to Hyperbole’s initialization. The Cust/Web-Search-Search
menu sets the option, hyperbole-web-search-browser-function,
which determines whether web search results are displayed
within Emacs or with an external web browser. A short
video introduction to the Find/Web menu may be
found at https://youtu.be/8lMlJed0-OM.
The Find/Web menu looks like this:
Web> Amazon Bing Dictionary Elisp Facebook Google gitHub Images
Jump Maps RFCs StackOverflow Twitter Wikipedia Youtube
All global button commands. Global buttons are accessed by name rather than by direct selection. The Hyperbole menubar menu also includes an activation menu item for each global button.
Return to previous positions in the button traversal history.
All implicit button commands.
Hyperbole-specific email messaging commands. Use this to send mail to a Hyperbole discussion mailing list.
Autonumbered, structured outliner commands with per-node hyperlink anchors. See Koutliner.
Hierarchical, multi-file contact manager lookup and edit commands. See HyRolo.
Window, frame and buffer display control commands. See HyControl.
Window configuration management commands, such as adding and restoring window configurations by name. See Window Configurations.
Hyperbole includes the fastest, easiest-to-use Emacs window and frame management system available, HyControl, found under the Hyperbole Screen menu. If you use a lot of Emacs windows or frames (typically, window system windows) then this chapter is for you.
HyControl interactively adjusts the layout of your windows and frames down to the pixel-level if desired. You adjust the location, size and display elements of your windows and frames until they look as you like and then simply quit HyControl and go back to work.
Hyperbole binds the key {C-c \} for quick access to HyControl’s window control menu, if it was not already bound prior to Hyperbole’s initialization; otherwise, the Screen/WindowsControl minibuffer menu item, {C-h h s w}, will do the same thing. To start HyControl with the frames menu instead, use Screen/FramesControl, {C-h h s f}.
Once in HyControl, your minibuffer window at the bottom of the selected frame will display a summary of keys you may use to adjust your windows until you press {q} or {Q} to quit from HyControl. The key, {t}, will always toggle between controlling frames and windows, the submodes of HyControl, with the upper left of the minibuffer prompt showing which type of control is active.
A number of commands take a single numeric argument, e.g. movement and sizing, which you can enter by typing a period to clear the argument, followed by any positive number up to 1000. You may also use the {C-u} universal argument key to apply a multiplier of 4 to the argument, any number of times. Any entry that pushes the argument over 1000, restarts it, so 10005 would produce an argument of 5.
The table below explains what each key does in HyControl mode. If the explanation does not say otherwise, then the key applies in both window and frame submodes.
Toggle whether HyControl displays key binding help in the minibuffer.
Clear the prefix argument to a value of 0.
Multiply the prefix argument by 10 and add the digit pressed (or subtract it if prefix argument is negative).
If HyControl mode was just enabled or the last command was prefix arg-related, invert the value of the prefix argument or if 0, set it to -1. Otherwise, depending on whether in Frames or Windows mode, shrink the frame or window to the minimum size needed to display its text.
Multiply the prefix argument by 4 each time this is pressed.
Display a grid of windows in the selected frame sized according to the prefix argument or via a prompted input. Left digit of the argument is the number of grid rows and the right digit is the number of grid columns to display. The buffers displayed in the grid are determined by the value of the prefix argument given to the command or by the selected items in the current window if in Buffer Menu, Ibuffer Menu or Dired mode.
With no prefix argument and no items chosen, the selected frame’s buffer list
is filtered through hycontrol-display-buffer-predicate-list, a list of
predicate/boolean filter functions. The default predicate selects existing
buffers with attached files and displays those.
With a prefix argument of 0, the user is prompted for a major mode name and the windows grid size. Only those buffers with the named major mode are displayed.
With a prefix argument < 0, the user is prompted for a shell glob-type file pattern; matching files are read into buffers and displayed in an auto-sized windows grid.
Otherwise, when the prefix argument is an invalid size, the windows grid command prompts for the grid size.
When done, this resets the persistent prefix argument to 1 to prevent following commands from using the often large grid size argument.
If you ever need to experiment with different sized window grids, use {M-x hycontrol-window-grid-repeatedly RET}. It will repeatedly prompt you for a grid size and then display it. When you are done, simply press {RET} to exit.
Programmatically, there are a number of ways to generate and display a windows grid.
hycontrol-windows-grid-by-file-pattern creates a windows grid from a glob file
pattern. It is bound to {C--1 C-c @}. hycontrol-windows-grid-by-buffer-list
creates a windows grid from a list of buffers or buffer names.
hycontrol-windows-grid-by-file-list creates a windows grid from a list of file
names.
Cycle through common width adjustments of a frame, such as 25% and
50%. Widths are given in screen percentages by the list
hycontrol-frame-widths and typically go from widest to
narrowest.
Cycle through common height adjustments of a frame, such as 33.3% and
75%. Heights are given in screen percentages by the list
hycontrol-frame-heights and typically go from tallest to shortest.
Increase height by argument lines (line height determined by buffer character height).
Shorten height by argument lines.
Widen by argument characters.
Narrow by argument characters.
In FRAMES mode, resize frame’s height and width to about argument percent of the screen size.
In FRAMES mode, resize frame’s height to about argument percent of the screen size.
In WINDOWS mode, the keys I, J, K, M move directionally (based on QUERTY key layout) between windows in the selected frame. In FRAMES mode, they move directionally through visible frames. These use the windmove and framemove libraries. When any of these keys are pressed, Hyperbole will prompt to install the needed library if not already installed.
In FRAMES mode, resize frame’s width to about argument percent of the screen size.
Move frame in the specified direction by argument pixels.
With each press, cycle the selected frame’s position clockwise through
the middle of edges and corners of the screen. With an argument of 0,
reset the cycle position to the upper left corner. Respects the pixel
edge offsets returned by hycontrol-get-screen-offsets.
Prompt for confirmation and then delete non-selected windows or frames based on mode.
In FRAMES mode, lower the selected frame below all other Emacs session frames.
Select the next window in the window list, across all visible frames.
Select the next visible frame.
In FRAMES mode, move the frame directly to the screen edge position given
by the numeric keypad layout. For example, 3 moves the frame to the
bottom right corner and 8 moves it to the middle of the top edge.
Keypad numeric keys do not adjust the argument. Respects the pixel edge
offsets returned by hycontrol-get-screen-offsets.
Display a virtual numeric keypad for emulating a keypad on keyboards without one. Each digit key operates just as a numeric keypad key would.
In FRAMES mode, raise the selected frame above all other Emacs session frames.
Create a new atop window or frame depending on mode. If a frame, it is
sized to the same size as the selected window and offset from the
selected frame by the pixel amounts given by
hycontrol-frame-offset.
Create a new sideways window or frame depending on mode.
Save the current window or frame configuration based on mode. Whenever, HyControl is invoked, the current window and frame configurations are saved automatically. So use this command only if you have changed the configuration and wish to save it temporarily.
After confirmation, restore the last saved window or frame configuration based on mode.
Clone the selected window to a new similarly sized frame. Delete the
original window unless there is only one window in the source frame or
if hycontrol-keep-window-flag is non-nil.
Select another window or frame in the given direction depending on the current HyControl mode. I=above, J=left, K=right and M=below.
Expand the selected frame to the respective screen edge based on U.S.
keyboard key layout. i=top, j=left, k=right and m=bottom screen edge.
If already at the edge, adjusts the perpendicular dimension to ARG percent
of the screen (50% by default if ARG is 1 or nil) but keep it at the screen
edge. Respects the pixel edge offsets returned by
hycontrol-get-screen-offsets.
After confirmation, in WINDOWS mode, make the current frame’s windows approximately the same size. In FRAMES mode, make all visible frames the size of the selected frame.
In WINDOWS mode, shrink window to its smallest possible number of lines to display the entire buffer, if possible. Otherwise or if the window is already displaying all of its lines, shrink it to about one line, if possible.
In FRAMES mode, make the frame as small as possible while still displaying it.
Make the window or frame (based on mode) as large as possible. In FRAMES mode, a second press of this key restores its size to whatever it was prior to the first use of this command.
Bury the selected buffer within the buffer list, displaying the next buffer.
Unbury the bottom buffer in the buffer list and display it in the selected window.
Swap two buffers between the selected window or frame and one other. In WINDOWS mode, there must be precisely two windows in the selected frame. In FRAMES mode, the second frame must have a single window.
Zoom in selected window or frame text based on mode, increasing default face size.
Zoom out selected window or frame text based on mode, increasing default face size. Zooming supports an argument of between 1 and 9 (any other value sets the argument to 1). The argument determines the number of sizes by which to zoom.
FRAMES mode zooming requires the separately available zoom-frm.el library. WINDOWS zooming works without this library.
Toggle between WINDOWS and FRAMES submodes.
Press {Q} to globally quit HyControl mode and restore normal key bindings.
Typically {q} works as well, unless in a help buffer where
{q} is bound to quit-window, then that is run instead of quitting
HyControl. A second press of {q} will then quit HyControl.
The rest of this section goes into some technicalities about HyControl settings. You may ignore it if you are not familiar with Emacs variables and functions or with customized Emacs.
HyControl allows placement of frames at screen edges and corners with the frame cycle command, {c}, and direct placement using the layout of the numeric keypad keys, if available, or the p virtual keypad key otherwise. (Note that a screen may span multiple physical monitors).
To prevent widgets and toolbars at the corners of the screen from
being obscured, HyControl can offset each frame from each screen edge
by a fixed number of pixels. These offsets are specified by the
variable,hycontrol-screen-offset-alist and can differ for each type of
screen; see its documentation for details. If you change its value,
then call hycontrol-set-screen-offsets to set any new offset
values. hycontrol-get-screen-offsets returns the list of offsets
in clockwise order starting from the top edge. Both functions display a
minibuffer message with the current offsets when called interactively.
When HyControl creates a new frame, it automatically sizes it to the
same size as the previously selected frame and offsets it from that
frame by the (X . Y) number of pixels given in the variable,
hycontrol-frame-offset.
The source code for the HyControl system is in hycontrol.el
within your Hyperbole source directory, given by hyperb:dir.
HyControl uses standard Emacs keymaps, so any keys can be rebound.
Remember that Hyperbole typically binds {C-c \} to the windows
control menu, but if you would like to bind either of the two
HyControl minor mode invocation commands to keys, they are,
hycontrol-enable-windows-mode and hycontrol-enable-frames-mode.
Generally, you need only one of these bound to a key since when you
press that key, the other command can be reached by pressing {t}.
The Hyperbole outliner, the Koutliner (pronounced Kay-outliner), produces structured, autonumbered documents composed of hierarchies of cells. Each cell has two identifiers, a relative identifier indicating its present position within the outline and a permanent identifier called an idstamp, suitable for use within hyperlink references to the cell. The idstamp is typically not displayed but is available when needed. See Autonumbering.
Cells also store their time of creation and the user who created the cell. User-defined attributes may also be added to cells. See Cell Attributes.
This chapter expands on the information given in the EXAMPLE.kotl file included with Hyperbole. Use {C-h h k e} to display that file, as pictured on the following page. It is an actual outline file that explains major outliner operations. You can test out the viewing, editing and motion commands with this file since a personal copy is made when you invoke this command. If you have already edited this file and want to start with a fresh one, give the command a prefix argument: {C-u C-h h k e}.
See Koutliner Keys, for a full summary of the key bindings and commands available in the Koutliner.

Next: Creating Outlines, Previous: Koutliner, Up: Koutliner [Contents][Index]
The Kotl/ menu entry on the Hyperbole minibuffer menu provides access to a number of major Koutliner commands:
Menu Item Command Description ==================================================================== All kotl-mode:show-all Expand all cells Blanks kvspec:toggle-blank-lines Toggle blank lines on or off Create kfile:find Edit or create an outline Downto kotl-mode:hide-sublevels Hide cells deeper than a level Examp <sample outliner file> Show self-descriptive example Format/ Submenu Import/Export commands Hide kotl-mode:hide-tree Hide tree with root at point Info <outliner documentation> Show outliner manual section Kill kotl-mode:kill-tree Kill the current tree Link klink:create Create a link to another cell Overvw kotl-mode:overview Show first line of each cell Show kotl-mode:show-tree Show tree with root at point Top kotl-mode:top-cells Collapse to top-level cells Vspec kvspec:activate Set a view specification ====================================================================
The popup and menubar Koutline menu, as displayed here, offers a more complete set of the Koutliner commands. {C-mouse-3} pops up the mode-specific menu in Emacs. Experiment with the menu or read the following sections explaining commands.
Next: Autonumbering, Previous: Menu Commands, Up: Koutliner [Contents][Index]
In addition to the Kotl/Create menu item, you can create and experiment with outline files simply by finding a file, {C-x C-f}, with a .kotl suffix. .kot will also work for users impaired by operating systems with 3-character suffix limitations.
When a new koutline is created, an invisible root cell is added. Its permanent and relative ids are both 0, and it is considered to be at level 0 in the outline. All visible cells in the outline are at level 1 or deeper, and thus are descendants of this root cell. Some koutliner commands prompt for cell numbers as arguments. An argument of 0 makes commands operate upon the entire outline.
An initial level 1 cell is also created to make it easy to start entering text in the outline. A koutline always has at least one visible cell in it.
See Autonumbering, which explains how cells are labeled according to their respective levels in the outline and how these labels are updated as the structure of the outline changes.
Next: Idstamps, Previous: Creating Outlines, Up: Koutliner [Contents][Index]
See Adding and Killing, for information on how to add new cells to or remove cells from a koutline. As you do this, or as you promote or demote cells within the outline, the labels preceding the contents of each cell automatically update to reflect the new structure. These labels are also known as autonumbers and as relative ids because they change as the structure changes.
The outline structure is shown by these labels and by the indentation of each outline level. Normally, each deeper level is indented another three characters, to reflect the nesting.
The default autonumbers are called alphanumeric labels because they alternate between using numbers and letters to distinguish each successive level. Each alphanumeric label uniquely identifies a cell’s position in an outline, so that there is no need to scan back to prior cells to see what the current section number of an outline is. This is similar to a legal numbering scheme but without all the period characters between level numbers. As an example, 1b3 is equivalent to a legal label of 1.2.3. Both refer to the 3rd cell at level 3, below the 2nd child of the first cell at level 1. Said another way, this is the 3rd child of the 1st cell’s 2nd child. In other words, it is easier to visualize hierarchies than to talk about them.
Alphanumeric labels are the default because they are shorter and easier to read aloud than equivalent legal ones. They also simplify distinguishing between even and odd level labels because of the alternating character set.
You can change the labeling scheme used in a particular outline with the command {C-c C-l}. A {?} will show all of the labeling options. The default, alpha labels, legal labels, and permanent idstamps (permanent cell ids) are all available.
A cell label is normally followed by a period and a space, called the label separator, prior to the start of the cell contents. You can change the separator for the current outline with {C-c M-l}. {C-u C-c M-l} will additionally change the default separator value used when new outlines are created (for the current session only). For example, use the value " " (two spaces) to get eliminate the trailing period after each cell label. The separator must be at least two characters long but may be longer.
If you find a separator that you prefer for all outlines, change the separator setting permanently by adding the following line to your Emacs initialization file, ~/.emacs, substituting for ‘your-separator’:
(setq kview:default-label-separator "your-separator")

Idstamps (permanent ids) are associated with each cell. They maintain hyperlinks as cells are reordered within a koutline. See Klinks. Idstamps may be displayed in place of the outline level relative ids. Use {C-c C-l id RET}.
An idstamp counter for each outline starts at 0 and is incremented by one each time a cell is added to the outline. This idstamp stays with the cell no matter where it is moved within the outline. If the cell is deleted, its idstamp is not reused.
The 0 idstamp is always assigned to the root node of the entire outline. This node is never visible within the outline, but is used so that the outline may be treated as a single tree when needed. Idstamps always begin with a 0, as in 012, to distinguish them from relative ids.

Text editing within the Koutliner works just as it does for other buffers, except when you need to deal with the structural components of an outline. Within the contents of a cell, all of your standard editing keys should work properly. You can just type in text and the left and right margins of the lines will be maintained for you. See Filling, for the times when you need to refill a paragraph or to control when filling occurs.
Don’t invoke editing commands with {M-x command-name RET} since the Koutliner uses differently named commands made to act like the regular editing commands. Koutliner commands, however, account for the structure and indentation in koutlines.
You may use the mouse to select parts of the contents of a single cell for editing. But don’t drag across cell boundaries and then edit the selected region, since that will destroy the outline structure.

Next: Promoting and Demoting, Previous: Editing Outlines, Up: Editing Outlines [Contents][Index]
{C-j} adds a new cell as a successor sibling of the current cell, that is, the next cell at the same level as the current cell. If you enter a positive number as a prefix argument, that number of cells will be inserted, all at the same level. {C-u C-j} is handled specially. It adds a single cell as a child of the current cell. {C-c a} does the same thing. {C-c p} adds the cell as the successor of the current cell’s parent.
{C-c C-k} kills the current cell and its entire subtree. {C-c k} kills the contents of a cell from point through the end of the cell; it does not remove the cell itself. {C-u C-c k} kills the entire contents of the cell regardless of the location of point. You may then yank the contents into another cell or another buffer with {C-y}.
Next: Relocating and Copying, Previous: Adding and Killing, Up: Editing Outlines [Contents][Index]
Demotion is the act of moving a tree down one or more levels in the outline. The new tree will become either the successor or the first child of the cell which precedes it in the outline. Promotion is the inverse operation. Note that trees (cells and their entire substructure) are promoted and demoted, not individual cells.
|-----------------------------+----------------------------| | Promotion Outside Org Table | Demotion Outside Org Table | |-----------------------------+----------------------------| | M-TAB or Shift-TAB | TAB | | M-<left> | M-<right> | | M-Shift-<left> | M-Shift-<right> | | C-c C-, | C-c C-. | | C-c C-< | C-c C-> | |-----------------------------+----------------------------|
Trees may be demoted or promoted by pressing TAB or {M-TAB}. {M-0 TAB} and {M-0 M-TAB} demote and promote trees and additionally refill each cell that is not specially marked to prevent refilling. See Filling. A positive or negative prefix argument to these commands promotes or demotes the tree up to a maximum of the number of levels given by the argument. The outline may not support movement of the tree by the number of levels requested, however, in which case the maximal possible adjustment is made.
{M-1 TAB} behaves specially. It toggles the function of
TAB and {M-TAB} so that they insert a tab
and remove the previous character, respectively. This is useful when
one is formatting information within a single cell. When in this
mode, {TAB} inserts a literal TAB character, by default.
Set the variable, kotl-mode:indent-tabs-mode, to
‘nil’ if you want space characters used to form the tab.
Use {M-1 TAB} to toggle the TAB and
{M-TAB} keys back to promoting and demoting trees.
The Koutliner also supports Org Table editing, see Tables in the Org Mode Manual, via Org table minor mode. Use {M-x
orgtbl-mode RET} to toggle this on and off. A press of the
Action Key on a | symbol, also toggles this minor mode on or
off.
Tree demotion and promotion keys match the defaults in Org mode and Outline mode, plus some easier to type ones. The tables below summarize which keys work whether inside an Org table or outside.
Note that you must use {M-0 TAB} and {M-0 M-TAB} to demote/promote Koutline trees when in a table since TAB and {M-TAB} move between fields within a table.
|----------------------------+-----------------------------| | Promotion Inside Org Table | Demotion Inside Org Table | |----------------------------+-----------------------------| | M-0 M-TAB | M-0 TAB | | C-c C-, | C-c C-. | | C-c C-< | C-c C-> | |----------------------------+-----------------------------|
Next: Moving Around, Previous: Promoting and Demoting, Up: Editing Outlines [Contents][Index]
Like Org mode, you can move the tree rooted at point past trees rooted at the same level with {M-<down>} and before trees with {M-<up>}. Give a prefix argument to move past that many other trees. (A 0 valued argument is automatically changed to 1).
For maximum flexibility in rearranging outlines, there are commands that move or copy entire trees anywhere within the outline as described in the table below. Each of these commands prompts for the label of the root cell to move or copy and for a second cell which specifies the new location for the moved or copied tree. You may either accept the default provided, type in the cell label, or when a mouse is available, simply double click with the Action Key on the contents of a cell. The Koutliner knows to use the cell’s label in such cases.
In the following commands, words delimited with <> represent the arguments for which each command prompts. Note how the use of prefix arguments changes each command’s behavior from insertion at the sibling level to insertion at the child level.
Move current tree back prefix arg same level trees.
Copy <tree> to follow as the first child of <cell>.
Copy <tree> to be the first child of the parent of <cell>.
Move <tree> to follow as the first child of <cell>.
Move <tree> to be the first child of the parent of <cell>.
If you have mouse support under Hyperbole, you can move entire trees with mouse clicks. Click the Assist Key within the indentation to the left of a cell and you will be prompted for a tree to move. Double click the Action Key within the contents of the root cell of the tree to move and then double click within the root contents of the tree you want it to follow as a successor.
The Koutliner supports copying and moving within a single outline only right now, so don’t try to to move trees across different outline files. You can, however, copy an outline tree to a non-outline buffer with:
Copy a <tree> to an outgoing mail message.
You may also import cells into the current koutline from another koutline with the {M-x kimport:text RET} command. See Inserting and Importing.
Next: Filling, Previous: Relocating and Copying, Up: Editing Outlines [Contents][Index]
In addition to normal emacs movement commands, you can move within a cell or from one cell or tree to another.
Move to the end of the current cell.
Move to the previous visible cell, regardless of level.
Move backward to this cell’s predecessor, if any.
Move to the parent cell of the current cell, if any.
Move to the first sibling at the current level within this tree.
Move to the last sibling at the current level within this tree.
Move to the last cell in the tree rooted at point, regardless of level.
Next: Transposing, Previous: Moving Around, Up: Editing Outlines [Contents][Index]
Filling is the process of distributing words among lines to extend short lines and to reduce long ones. Commands are provided to fill a paragraph within a cell or to fill a whole cell, which may have multiple paragraphs.
{M-q} or {M-j} refills a paragraph within a cell so that its lines wrap within the current margin settings. {C-c M-q} or {C-c M-j} refills all paragraphs within a cell. {C-M-q} or {C-M-j} refills all cells within a tree. See the GNU Emacs manual for information on how to set the left and right margins.
Set the variable, kotl-mode:refill-flag, to ‘t’ if you
want moving, promoting, demoting, exchanging, splitting and appending
cells to also automatically refill each cell, aside from any that have
a ‘no-fill’ property. Generally, this is not recommended since if you
happen to move a cell that you carefully formatted yet forgot to give
a ‘no-fill’ property, then your formatting will be lost.
Next: Splitting and Appending, Previous: Filling, Up: Editing Outlines [Contents][Index]
The Koutliner move and copy commands rearrange entire trees. The following two commands, in contrast, exchange the locations of two individual cells.
{C-c e} prompts for two cell addresses and exchanges the cell locations.
{C-c t} does not prompt. It exchanges the current and immediately prior cell, regardless of their levels. If there is no prior cell it exchanges the current and next cell.
{M-0 C-c t} exchanges the cells in which point and mark fall. {C-c t} with a non-zero numeric prefix argument, N, moves the current tree maximally past the next N visible cells. If there are fewer visible, it makes the current cell the last cell in the outline.
Next: Inserting and Importing, Previous: Transposing, Up: Editing Outlines [Contents][Index]
One cell may be split into two adjacent sibling cells with {C-c s}. This leaves the cell contents preceding point in the current cell, minus any trailing whitespace, and moves the contents following point to a new sibling cell which is inserted into the outline. {C-u C-c s} instead adds the new cell as the first child of the original cell, rather than as its successor.
All cell attributes in the original cell are propagated to the new one, aside from the creation attributes and idstamp.
{C-c +} appends the contents of a specified cell to the end of another cell. It has no effect on cell attributes, except that if one cell has a ‘no-fill’ attribute, which prevents all but user requested filling of a cell, then the cell appended to inherits this property. This helps maintain any special formatting the appended text may have.
Next: Exporting, Previous: Splitting and Appending, Up: Editing Outlines [Contents][Index]
The paragraphs of another buffer or file may be inserted into a koutline as a set of cells by using the {C-x i} command. When prompted, you may use a buffer name or filename from which to insert; completion is provided for filenames only.
The elements from the original buffer are converted into kcells and inserted as the successors of the current cell. If {C-u C-x i} is used, they are instead inserted as the initial children of the current cell.
For information on mode and suffix-specific conversions performed on
file elements before they are inserted, see the documentation for the
variables, kimport:mode-alist and kimport:suffix-alist. This
same conversion process applies if you invoke {M-x kotl-mode
RET} in a non-koutline buffer or if you perform a generic file import
as described later in this section.
Use {M-x kimport:insert-file-contents RET} to insert an entire file into the current cell following point.
The outliner supports conversion of three types of files into koutline files. You can import a file into an existing koutline, following the tree at point, or can create a new koutline from the imported file contents. {C-h h k f f} or {M-x kimport:file RET} selects the importation type based on the buffer or filename suffix of the file to import.
If you want to convert a buffer from some other mode into a koutline and then want to save the converted buffer back to its original file, thereby replacing the original format, use {M-x kotl-mode RET}. Remember that you will lose the old format of the buffer when you do this.
Use one of the following commands when you need explicit control over the type of importation used on some text. With these commands, your original file remains intact.
Use {M-x kimport:text RET} and you will be prompted for a text buffer or file to import and the new koutline buffer or file to create from its text. Each paragraph will be imported as a separate cell, with all imported cells at the same level, since indentation of paragraphs is presently ignored. This same command can be used to import the contents, attributes and level structure of cells from another koutline.
Star outlines are standard emacs outlines where each entry begins with one or more asterisk characters. Use {M-x kimport:star-outline RET} and you will be prompted for the star outline buffer or file to import and the new koutline buffer or file to create.
(Skip this if you are unfamiliar with the Augment/NLS system originally created at SRI.) Files exported from the Augment system as text often have alphanumeric statement identifiers on the right side. You can import such files while maintaining their outline structure. Use {M-x kimport:aug-post-outline RET} and you will be prompted for the Augment buffer or file to import and the koutline to create. See https://dougengelbart.org/content/view/148/ for more information.
Previous: Inserting and Importing, Up: Editing Outlines [Contents][Index]
Koutlines may be exported to other file formats. Presently, the only format supported is conversion to HTML for publishing on the World-Wide Web. Use the Kotl/Format minibuffer menu, {C-h h k f}, for this.
{C-h h k f d} or {M-x kexport:display RET} exports the
current Koutline buffer to a temporary HTML file and displays the file
in the web browser given by browse-url-browser-function. Any tree
in the HTML outline may be expanded or collapsed by clicking the left
mouse button on its root cell, for ease of viewing.
Alternatively, {C-h h k f h} or {M-x kexport:html RET} prompts for the koutline buffer or file to export, the HTML file or buffer to which to output, and the title to use for the HTML file. Completion of filenames is provided. The conversion will then be done and the output file or buffer will be written; the output file will not be displayed. You must display it manually, if desired.
{C-h h k f k} or {M-x kexport:koutline RET} exports the current Koutline buffer to a .html file of the same name. The output file will not be displayed; you must display it manually, if desired.

The Koutliner has very flexible viewing facilities to allow you to effectively browse and study large amounts of material.
| • Hiding and Showing: | ||
| • View Specs: |
Next: View Specs, Previous: Viewing Outlines, Up: Viewing Outlines [Contents][Index]
Individual cells, branches, or particular levels in the outline may be hidden or shown. These commands work even when an outline buffer is read-only, e.g. when its file is not checked out of a version control system yet, so that you can get effective views of an outline without editing it. Some of these commands affect the current view spec. See View Specs.
Here are the major commands for showing and hiding Koutline cells.
Show (expand) the tree rooted at point.
Show (expand) all of the cells in the outline. With a prefix arg, also toggle the display of blank lines between cells.
Show all of the cells down to a particular <level>. You are prompted for the level or a prefix argument may be given.
Show the subtree at point. Use {C-c C-s} to achieve a similar effect; the only difference is that it will additionally expand the root cell.
Show an overview of the outline by showing only the first line of every cell. With a prefix arg, also toggle the display of blank lines between cells.
Show a top-level view of the outline by hiding all cells but those at level 1 and collapsing the visible cells so that only their first lines are visible. With a prefix arg, also toggle the display of blank lines between cells.
A click or a press of the Action Key within a cell’s body, but not on a Hyperbole button, toggles between hiding and showing the tree rooted at point. Try it with either your mouse or with {M-RET}.
Previous: Hiding and Showing, Up: Viewing Outlines [Contents][Index]
View specifications (view specs, for short) are short codes used
to control the view of a koutline. The view specs in effect for an
outline are always displayed in the modeline of the outline’s window,
following the outline buffer name, unless the variable,
kvspec:string, has been set to ‘nil’ to disable view spec
display. The modeline display appears as <|viewspec> to aid rapid
visual location. The | (pipe character) is also used in links that
specify view specs to indicate the start of a view spec sequence.
See Klinks.
The current view spec is saved whenever the outline is saved. The next time the outline is read in, the same view spec will be applied.
The rest of this section documents the view spec characters that are presently supported and explains how to invoke a view spec. There is no user-level means of adding your own view spec characters, so all other character codes are reserved for future use.
{C-c C-v} prompts for a new view spec setting in which the following codes are valid. Any invalid characters in a view spec are ignored. Characters are evaluated in an order meant to do the right thing, even when you use conflicting view spec characters. The standard initial view spec is <|ben>.
Show all cell levels and all lines in cells.
Turn on blank lines between cells. Without this character, blank lines will be turned off. You may also use the {C-c b} key binding to toggle blank lines on and off independently of any other view settings.
Hide any lines greater than N in each cell. 0 means don’t cutoff any lines.
Show ellipses when some content of a cell or its subtree is hidden. This cannot be turned off.
Hide cells at levels deeper than N. 0 means don’t hide any cells.
Turn on the default label type, as given by the variable,
kview:default-label-type. Normally, this is alphanumeric labels.
Display legal labels, e.g. 1.4.3
As a test, use {C-h h k e} to display the example koutline. Then use {C-c C-v} to set a view spec of ‘c2l1’. This will turn off blank lines, clip each cell after its second line, and hide all cells below level one.
Next: Cell Attributes, Previous: Viewing Outlines, Up: Koutliner [Contents][Index]
Cells may include hyperlinks that refer to other cells or to external sources of information. Explicit Hyperbole buttons may be created as usual with mouse drags (see Creation Via Action Key Drags). Implicit Hyperbole buttons may be added to Koutline text as well. A klink is a special implicit link button, delimited by <> separators, that jumps to a koutline cell and may also adjust the current outline viewspecs. This section discusses klinks.
There are three forms of klinks:
‘<#2b=06>’ is an internal klink, since it refers to the koutline in which it is embedded. When activated, it jumps to the cell within the current outline which has permanent id ‘06’ and relative id ‘2b’. ‘<#06>’ does the same thing, as does ‘<#2b>’, though this latter form will not maintain the link properly if the cell is moved elsewhere within the outline. The form, ‘<#2b=06|ben>’ additionally sets the view spec of the current outline back to the default value, with a blank line between each cell and the whole outline visible.
The second klink format is an external link to another koutline, such as, ‘<EXAMPLE.kotl#3=012|c1e>’, which displays the named file, starting at the cell 3 (whose permanent identifier is 012), with the view specification of: blank lines turned off, cutoff after one line per cell, and showing ellipses for cells or trees which are collapsed.
The third format sets a view spec for the current koutline. For example, ‘<|ben>’, when activated, sets the view in the current outline to display blank lines, to use ellipses after collapsed lines and to label cells with the alphanumeric style.
Press the Action Key over a klink to follow it. This will flash the klink as a button and then will display its referent in the other window. If the klink contains a view spec, it will be applied when the referent is displayed.
There are a number of easy ways to insert klinks into koutlines. If you have mouse support under Hyperbole, simply click the Action Key within the indentation to the left of a cell text. If you then double click on some cell, a link to that cell will be inserted where you started. From a keyboard, use {C-c l} when in a koutline or {C-h h k l} when not in a koutline to insert a klink. Since klinks are implicit buttons, you may instead type in the text of the klink just as you saw them in the examples above and they will work exactly as if they had been entered with the insert link command.
If you prefer the standard copy and yank model that Emacs provides, place point within a klink when there is no active region and use {M-w} to copy the klink. To instead copy a reference to the current Koutline cell, use {M-w} outside of a klink when no region is active or {M-x kotl-mode:copy-absolute-klink-to-kill-ring RET} anywhere within a cell. Then {C-y} will yank the last copied text into any buffer you desire. Of course, when a region is active, {M-w} will copy the region as it does normally in Emacs.
Similarly, you can copy to an Emacs register rather than to the kill ring. When no region is active/highlighted, {C-x r s} prompts for an Emacs register and saves to it either the current klink or, when outside of a klink, a reference to the current cell. {M-x kotl-mode:copy-absolute-klink-to-register RET} anywhere within a cell saves a reference to the current cell to a register.
{C-x r i} with the same register then inserts at point the Koutline reference previously saved. When a region is active, these operate on the region instead.
There are also commands without any builtin key bindings that always copy a klink reference to the current cell:
kotl-mode:copy-absolute-klink-to-kill-ring kotl-mode:copy-relative-klink-to-kill-ring kotl-mode:copy-absolute-klink-to-register kotl-mode:copy-relative-klink-to-register
Because klinks use a very generic syntax, surrounded by <angle brackets>,
in certain modes, mostly C-based programming modes, certain non-klink syntax
can be mistakenly identified as klinks. Therefore, the Koutliner provides
two customizable variables which disable klink recognition in selected major
modes, klink:ignore-modes and klink:c-style-modes. Add a mode
to one of these if you find any syntax that improperly registers as a klink.
klink:ignore-modes is for non-programming modes, as Hyperbole ensures
that within all programming major modes, klinks are recognized only when point
is within a comment.
klink:c-style-modes is rarely needed but is there if Hyperbole ever
mistakenly recognizes a pattern within a comment as a klink when it isn’t.
Next: Koutliner History, Previous: Klinks, Up: Koutliner [Contents][Index]
Attributes are named properties whose values are specific to an outline cell. Thus, each cell, including the invisible 0 root cell, has its own attribute list. Every cell has three standard attributes:
The permanent id of the cell, typically used in cross-file hyperlinks that reference the cell, this is a whole number that starts from 0, which is always the hidden root cell of the outline tree.
The e-mail address of the person who created this cell.
The time at which the cell was created. This is stored in a form that allows for easy data comparisons but is displayed in a human readable format, such as ‘Jan 28 18:27:59 CST 2021’.
{C-c C-i} adds, modifies or removes an attribute from a cell. The prefix argument given to this command determines what it does.
sets an attribute of the cell at point; setting an attribute’s value to ‘nil’ is the same as removing it.
removes an attribute of the cell at point
sets an attribute of the invisible 0 root cell
removes an attribute of the invisible 0 root cell
The ‘no-fill’ attribute is special. When set to ‘t’, it
prevents movement, promotion, demotion, exchange, split or append
commands from refilling the cell, even if the variable,
kotl-mode:refill-flag, is set to ‘t’. It does not prevent
you from invoking explicit commands that refill the cell.
See Filling.
{C-c h} prompts for a cell label and displays the cell’s attributes. {C-u C-c h} prompts for a cell label and displays the attributes for it and its subtree; use 0 as the kcell id to see attributes for all visible cells in the outline.

Much of the Hyperbole outliner design is based upon concepts pioneered in the Augment/NLS system, [Eng84a]. Augment treated documents as a hierarchical set of nodes, called statements, rather than cells. Every Augment document utilized this intrinsic structure.
The system could rapidly change the view of a document by collapsing, expanding, generating, clipping, filtering, including or reordering these nodes. It could also map individual views to multiple workstation displays across a network to aid in distributed, collaborative work.
These facilities aided greatly in idea structuring, cross-referencing, and knowledge transfer. The Koutliner is a start at bringing these capabilities back into the mainstream of modern computing culture.

Hyperbole includes a complete, advanced rolo system, HyRolo, for convenient management of hierarchical, record-oriented information. Most often this is used for contact management but it can quickly be adapted to most any record-oriented lookup task requiring fast retrieval.
Hyperbole buttons may be included within rolo records and then manually activated whenever their records are retrieved in a search.
The following subsections explain use and basic customization of this tool.

Next: HyRolo Menu, Previous: HyRolo, Up: HyRolo [Contents][Index]
HyRolo manages and searches a list of rolo files stored in the
hyrolo-file-list custom option. A rolo file consists of
an optional header that starts and ends with a line of equal signs (at
least three equal signs starting at the beginning of a line), followed
by zero or more rolo records which we call entries.
The first file in the list should be a user-specific hyrolo file, typically in the home directory and must have a suffix of either .org (Org mode) or .otl (Emacs Outline mode). Other files in the list may use suffixes of .org, .otl, .md (Markdown mode) or .kotl (Koutline mode).
HyRolo entries begin with a delimiter of one or more special characters followed by another space. Delimiters vary based on the type of file, for example level 3 entry delimiters look like this:
Emacs Outline Mode: *** Koutline Mode: 1b3 or 1.2.3 Markdown Mode: ### Org Mode: ***
Entries may be arranged in a hierarchy, where child entries start with at least one more delimiter characters than do their parents. Top-level entries use either a single delimiter character or a sequence of digits in the case of Koutlines.
Beyond this initial delimiter, entries are completely free-form text. It is best to use a "lastname, firstname" format, however, when adding contact entries into the first HyRolo file in your list. Then HyRolo will automatically keep your entries alphabetized as you add them; HyRolo can also sort the entries if you ever need. HyRolo will use this ordering if you accept the default entry with which it prompts you when adding a new entry.
Here is an example of a simple HyRolo file. The date at the end is
automatically added by HyRolo whenever a new record is added, unless
hyrolo-date-format is set to the empty string.

Any search done on the rolo scans the full text of each entry. During a search, the rolo file header separator lines and anything in between are appended to the buffer of matched entries before any entries are retrieved from the file. Whenever an entry is matched, it and all of its descendant entries are retrieved. If your emacs version supports textual highlighting, each search match is highlighted for quick, visual location.
For example, a search on "Company" could retrieve the following:
==================================================================
COMPANY ROLO
==================================================================
* Company
** Manager
*** Staffer
Thus, searching for Company retrieves all listed employees. Searching for Manager turns up all Staffer entries.

The Rolo submenu of the Hyperbole menu offers a full set of commands for searching and maintaining a personal address book. It looks like so.
The Rolo/ menu entry on the Hyperbole minibuffer menu provides the same set of commands as the menubar Rolo menu but with more concise labels.
The minibuffer Rolo/ menu offers the following commands (ConsultFind and HelmFind appear only when associated packages are loaded but are especially noteworthy as they allow for line-level searching with interactive search pattern narrowing):

The ’File’ menu item displays and edits the first file listed in
hyrolo-file-list unless given a prefix argument, in which case
it prompts with completion for the file to edit.
A prefix argument used with any of the above menu items that have ’Find’ in their names limits the search to a maximum number of matches given by the argument. The search is terminated whenever that number of matches is found.
With any of the above commands that prompt for a HyRolo name, such as Edit or Add (not the Find commands), you may use the form parent/child to locate a child entry below a specific parent. Hence, for a HyRolo which looks like so:
* Company ** Manager *** Staffer
you can refer to the Staffer entry with the following hierarchical notation, Company/Manager/Staffer. This hierarchical notation is not used in search expressions since they search the entire HyRolo anyway. Thus, "Staffer" as a search pattern will find an entry containing "Staffer" at any level in a hierarchy, like so:
*** Staffer

See HyRolo Menu, for the list of HyRolo search commands. In this section, the menu item names from the minibuffer menu are used to refer to each command.
The RegexFind menu item searches the rolo list for all entries
which contain matches for a given regular expression. The regular
expression syntax used is the same as the one used within Emacs
and across the GNU set of tools. See Syntax of Regular
Expressions in the GNU Emacs Manual, for full documentation on this
format.
The WordFind menu item locates full-word matches so that if you
search for ‘product’, it won’t match to occurrences of
‘production’. It is also handy for more precise name matching.
The StringFind menu item has two uses. It can find all entry
matches for a string or can execute logical queries for more
precise matching. The format of logical queries is explained here; a
simple parenthesis delimited prefix format is used with the following
logical operators.
Operator Name Num of Args Description ===================================================================== and two or more Match entries with all str args or two or more Match entries with any str args xor two or more Match entries with exactly 1 str arg not one Match entries without the str arg r-and two or more Match entries with all regexp args r-or two or more Match entries with any regexp args r-xor two or more Match entries with exactly 1 regexp arg r-not one Match entries without the regexp arg =====================================================================
For example:
(and Company (not Vice-President))
would match those entries for people associated with ‘Company’ who do not have ‘Vice-President’ titles.
The following example would provide a list of all people marked as clients whose area codes are outside of 408 and all non-clients within the 408 area code. This could be useful after all clients within the 408 area code have been contacted and you want to see who else you should contact.
(xor client 408- )
When using the regular expression operators, your operands are sent as regular expressions without the need to quote single words or special regular expression characters like ’*’ and ’?’. Use double quote marks to include a phrase or multi-word regular expression pattern to match. For example:
(r-and HyRolo "Red Buttons?")
would match entries that contain both "HyRolo" and either "Red Button" or "Red Buttons".
Next: HyRolo Settings, Previous: HyRolo Searching, Up: HyRolo [Contents][Index]
After a rolo search is performed, point is left in the rolo
match buffer, *HyRolo*, which uses hyrolo-mode to
simplify browsing many HyRolo matches. Press {?} when in the
match buffer for a summary of available keys, all of which are
documented in this section.
If your HyRolo search did not match what you want, use {r} to start a new regular expression query or {C-u r} for a string query. The rest of the match buffer keys work with the search results currently displayed.
If your emacs version supports textual highlighting, each search match is highlighted for quick, visual location. {TAB} moves point forward to successive spans of text which match the search expression. If the matching text is hidden/invisible, it is shown; the body of the entry with the match, as well as all of its sub-entries are shown. {M-TAB} or {SHIFT-TAB} move point backward to earlier matches. These keys allow you to quickly find the matching entry of most interest to you if your search expression failed to narrow the matches sufficiently.
To extend the match expression with some more characters to find a particular entry, use {M-s}. This performs an interactive search forward for the match expression. You may add to or delete characters from this expression to find different occurrences or move to the next match with {C-s}. {C-r} reverses the direction of the search.
To search for a specific entry name in the match buffer, use {l} to interactively locate the text immediately following the entry start delimiter, typically one or more asterisks. This lets you find entries by last name quickly, eliminating other matches. Standard string, {C-s}, and regular expression, {C-M-s}, interactive search commands are also available within the rolo match buffer.
Single key outlining commands are also available for browsing matches. If your search matches a large number of entries, use {t} to get a top-level summary of entries. Only the first line of each first-level match is shown. If you want to see an overview of all the levels, use {o} which shows the first line of every entry level. If you want an overview of just the first two levels, {C-u 2 o} will work.
Press {s} to show (expand) the entry at point if it is hidden (collapsed). If point is on a file header, this will expand the header and show the entire set of matched entries for the file. The {h} does the reverse and hides entries. Within file headers it hides the file from the end of the current line forward, so you can leave parts of the header displayed, if desired. Press {a} to expand all entries in the buffer across all matched files.
If an entry is collapsed/hidden, moving to any hidden part auto-expands it. Use {h}, the hide entry subtree to hide it again, if desired; this leaves point at the beginning of the entry (does not apply in file headers) to facilitate further use of movement by entry commands.
Other keys are defined to help you work with matching entries.
Move to the previous entry at the same level as the current entry.
Move to the next entry at the same level as the current entry.
Move to the beginning of the entry. With a prefix argument, move to the beginning of highest ancestor level.
Move to the end of the entry. With a prefix argument, move to the end of the entire subtree.
Move to previous file/buffer location header beginning with @loc>.
Move to next file/buffer location header beginning with @loc>.
Scroll forward a windowful.
Use the {e} key to jump to and edit the current line in its original
source file. If on a rolo entry and it contains a datestamp at its end,
update the datestamp, unless this feature has been turned off via the
Cust/Toggle-Rolo-Dates menu item. The variable, hyrolo-edit-hook,
performs this update. This allows programmed modification of the way
rolo edits work. The variable, hyrolo-add-hook, works the same
way but is evaluated when a new entry is first added. The format of the
datestamp is specified by hyrolo-date-format.
Once you have found an entry of interest and you want to remove the rolo match buffer, use {q} to quit. This will restore your current frame to its state prior to the rolo search.
Previous: HyRolo Keys, Up: HyRolo [Contents][Index]
The files used in any rolo search are given by the
hyrolo-file-list variable, whose default value is typically
"~/.rolo.otl", in which case, searches scan only your personal
rolo file. But you can customize this to include files with variables
in them, wildcard patterns and directories, as explained below. Any
paths added to this list should be absolute.
If you include file wildcards in paths for this variable and
find-file-wildcards is non-nil (the default), then any files
matching the pattern (which can include [char-matches] or * wildcards
and regular text) when the variable is set will be included in HyRolo
searches. For more on wildcards, see Wildcards in the GNU
Emacs Manual.
If you include an Environment variable or Emacs Lisp variable with the
${var} format in a path, they also are resolved when
hyrolo-file-list is set. Variables with values that include
multiple paths, e.g. PATH, are resolved to the first existing entry
that matches.
If you include an existing directory (invalid ones are ignored) in
your hyrolo-file-list, HyRolo will expand it recursively across
all of its files that match hyrolo-file-suffix-regexp. By
default, this is Org files (.org), Emacs outlines (.otl), Koutlines
(.kotl), or Markdown files (.md). See hpath.el#hpath:expand-list.
Once expanded, if a file in the list does not exist or is not readable, it is dropped. Paths are searched in the order in which they appear in the list. You should leave your personal rolo file as the first entry in the list, since this is the only file to which the HyRolo menu Add command adds entries.
Hyperbole releases earlier than 4.17 used a different filename for the personal rolo. If such a file exists, you will be prompted to rename it whenever the HyRolo system is loaded.
If you want to have HyRolo search your directory of Org files, add the following to your Emacs initialization file:
(add-hook ’hyperbole-init-hook
(lambda ()
(require ’org)
(setq hyrolo-file-list (append (hyrolo-initialize-file-list)
(list org-directory)))))
If you use the Big Brother DataBase (BBDB) Emacs package to capture
email addresses and store contact information, the rolo automatically
works with it. If the BBDB package is loaded before HyRolo, then your
bbdb-file of contacts is added as the second entry in
hyrolo-file-list and will be searched automatically for any matches by
the rolo find commands. Presently there is no support for editing
BBDB entries, just finding them.
For finding matches within only BBDB, there are the commands
hyrolo-bbdb-fgrep (string finding) and hyrolo-bbdb-grep
(regular expression finding). They may be bound to keys if desired.
If you use Google/Gmail Contacts, you can configure the HyRolo to query your Google Contacts for matches. First you must download and install the external google-contacts package using the Emacs Package Manager. Then you must install the non-Emacs GNU Privacy Guard (GPG) package from https://gnupg.org so that the gpg or gpg2 executable is in your command-line search path. Once these are in place, either restart Emacs or use {M-x hyrolo-initialize-file-list RET} to add Google Contacts to your searches.
When you next do a search, you will be prompted for your Google Contacts password and may also have to enter an authorization code that will be displayed on your screen. After authorization, your your information will be cached so that you are not prompted for it again within this Emacs session.
For finding matches within only Google Contacts, there are the commands
hyrolo-google-contacts-fgrep (string finding) and
hyrolo-google-contacts-grep (regular expression finding). They
may be bound to keys if desired.
If you ever need to disable Google Contacts usage, there is a
flag, hyrolo-google-contacts-flag, which when set to ‘nil’
disables searching of your Google Contacts.
Below are the rest of the settings available with HyRolo:
hyrolo-highlight-face
If textual highlighting is available in your emacs on your current
display type, the rolo uses the value of hyrolo-highlight-face as
the face which highlights search matches.
hyrolo-kill-buffers-after-use
HyRolo file buffers are left around after they are searched, on the
assumption that another search is likely to follow within this emacs
session. You may wish to change this behavior with the following
setting: (setq hyrolo-kill-buffers-after-use t).
hyrolo-save-buffers-after-use
After an entry is killed, the modified rolo file is automatically
saved. If you would rather always save files yourself, use this
setting: (setq hyrolo-save-buffers-after-use nil).
hyrolo-email-format
When an entry is being added from within a mail reader buffer, the
rolo extracts the sender’s name and e-mail address and prompts you
with the name as a default. If you accept the default, it will enter
the name and the email address using the format given by the
hyrolo-email-format variable. See its documentation if you want to
change its value.
hyrolo-hdr-regexp
A rolo file may begin with an optional header section which is copied
to the match display buffer whenever any matches are found during a
search. The start and end lines of this header are controlled by the
regular expression variable, hyrolo-hdr-regexp, whose default value
is "^===". This allows lines of all equal signs to visually separate
matching entries retrieved from multiple files during a single search.
hyrolo-hdr-and-entry-regexp
The rolo entry start delimiter is given by the regular expression
variable, hyrolo-hdr-and-entry-regexp, whose default value is "^\*+", i.e.
one or more asterisks at the beginning of a line.
hyrolo-display-format-function
When a rolo search is done, each matching entry is passed through the
function given by the variable, hyrolo-display-format-function,
before it is displayed. This should be a function of one argument,
namely the matching rolo entry as a string. The string that this
function returns is what is displayed in the rolo match buffer. The
default function used is identity which passes the string through
unchanged. If you use the rolo code to search other kinds of
record-oriented data, this variable can be used to format each entry
however you would like to see it displayed. With a little experience,
you can quickly write functions that use local bindings of the rolo
entry and file settings to search all kinds of record-oriented data.
There is never a need to learn a complicated query language.

This chapter explains Hyperbole’s hywconfig.el library. It lets you save and restore window configurations, i.e. the layout of windows and buffers displayed within an emacs frame. This is useful to save a particular working context and then to jump back to it at a later time during an emacs session. It is also useful during demonstrations to display many informational artifacts all at once, e.g. all of the windows for a particular subsystem. None of this information is stored between emacs sessions, so your window configurations will last through only a single session of use. Each window configuration is tied to the emacs frame in which it is created.
The hywconfig library offers two independent ways of managing window configurations. The first way associates a name with each stored window configuration. The name may then be used to retrieve the window configuration later. The second way uses a ring structure to save window configurations and then allows cycling through the ring of saved configurations, finally wrapping around to the first entry after the last entry is encountered. Simply stop when the desired configuration is displayed.
The Win/ menu entry on the Hyperbole top-level menu displays a menu of hywconfig window configuration commands:
WinConfig> AddName DeleteName RestoreName PopRing SaveRing YankRing
The operations on this menu are defined as follows.
Menu Item Command Description ===================================================================== AddName hywconfig-add-by-name Name current wconfig DeleteName hywconfig-delete-by-name Delete wconfig by name RestoreName hywconfig-restore-by-name Restore wconfig by name PopRing hywconfig-delete-pop Restore and delete wconfig SaveRing hywconfig-ring-save Store wconfig to the ring YankRing hywconfig-yank-pop Restore the next wconfig =====================================================================
The easiest method to save and restore window configurations shown here is by name, but it requires that you type the chosen name. Instead, the ring commands permit saves and restores using only the mouse. Since the ring commands are a bit more complex than their by-name counterparts, the following paragraphs explain them in more detail.
HyWconfig creates a ring structure that operates just like the Emacs
kill-ring (see Kill Ring in the GNU Emacs Manual) but its
elements are window configurations rather than text regions. You can
add an element to the ring to save the current window configuration in
the selected frame. After several elements are in the ring, you can
walk through all of them in sequence until the desired configuration
is restored.
SaveRing executes the hywconfig-ring-save command which
saves the current window configuration to the ring.
YankRing executes the hywconfig-yank-pop command. It restores
the window configuration currently pointed to within the ring. It
does not delete this configuration from the ring but it does move the
pointer to the prior ring element. Repeated calls to this command
thus restore successive window configurations until the ring pointer
wraps around. Simply stop when a desired configuration appears and
use {q} to quit from the minibuffer menu.
PopRing calls the hywconfig-delete-pop command. It is used to
restore a previously saved configuration and to delete it from the ring.
Simply stop when a desired configuration appears and use {q} to
quit from the minibuffer menu.
The maximum number of elements the ring can hold is set by the
hywconfig-ring-max variable whose default is 10. Any saves beyond
this value will delete the oldest element in the ring before a new one
is added.

This chapter is for people who wish to customize Hyperbole, to extend it, or to develop other systems using Hyperbole as a base. Most of it requires a basic level of familiarity with Emacs Lisp, though new implicit button types may be created with knowledge of only Emacs regular expressions.

Hyperbole supplies a number of hook variables that allow you to adjust its basic operations to meet your own needs, without requiring you to change the code for those operations.
We find it best to always set the value of hook variables either to
‘nil’ or to a list of function names of no arguments, each of which
will be called in sequence when the hook is triggered. If you use
the add-hook function to adjust the value of hooks, it will do
this automatically for you.
Given the name of a function, a Hyperbole hook variable triggered within that function has the same name as the function with a ‘-hook’ appended. Hyperbole includes the following hook variables:
hyperbole-init-hook
For customization at Hyperbole initialization time. Use this to load any personal Hyperbole type definitions or key bindings you might have. It is run after Hyperbole support code is loaded but before Hyperbole is initialized, i.e. prior to keyboard and mouse bindings.
action-key-depress-hook
assist-key-depress-hook
Run after an Action or Assist Mouse Key depress is detected.
action-key-release-hook
assist-key-release-hook
Run after an Action or Assist Mouse Key release is detected, before any associated action is executed.
action-act-hook
Run before each Hyperbole button activation.
The variable hbut:current contains the button to be activated when
this is run.
ebut-create-hook
Adds to the Hyperbole explicit button creation process.
ebut-delete-hook
Adds to the Hyperbole explicit button deletion process.
ebut-modify-hook
Executed when an explicit button’s attributes are modified.
hibtypes-begin-load-hook
Executed prior to loading of standard Hyperbole implicit button types. Used to load site-specific low priority implicit button types since lowest priority ibtypes are loaded first.
hibtypes-end-load-hook
Executed after loading of standard Hyperbole implicit button types. Used to load site-specific high priority implicit button types since highest priority ibtypes are loaded last.
htype-create-hook
Executed whenever a Hyperbole type (e.g. action type or implicit button type) is added to the environment.
htype-delete-hook
Executed whenever a type is deleted from the environment.
kotl-mode-hook
Executed whenever a koutline is created or read in or when kotl-mode is invoked.
hyrolo-add-hook
Executed after the addition of a new rolo entry.
hyrolo-display-hook
Executed when rolo matches are displayed.
hyrolo-edit-hook
Executed after point is successfully moved to an entry to be edited.
hyrolo-mode-hook
Executed when a rolo match buffer is created and put into hyrolo-mode.
hyrolo-yank-reformat-function
A variable whose value may be set to a function of two arguments, START and END, which give the region of the rolo entry yanked into the current buffer by the hyrolo-yank command. The function may reformat this region to meet user-specific needs.
Hyperbole also makes use of a number of standard Emacs hook variables.
find-file-hook
This is called whenever a file is read into a buffer. Hyperbole uses it to highlight any buttons within files.
write-file-hooks
This is called whenever a buffer is written to a file. Hyperbole uses it to save modified button attributes associated with any file from the same directory as the current file.
Hyperbole mail and news facilities also utilize a number of Emacs hook variables. These hide button data and highlight buttons if possible. See the Hyperbole files with ‘mail’ and ‘gnus’ in their names for specific usage of such hooks.
Next: Explicit Button Technicalities, Previous: Hook Variables, Up: Developing with Hyperbole [Contents][Index]
To define or redefine a single Hyperbole type, you may either:
(eval-defun) (only works in Emacs Lisp mode);
(eval-last-sexp) (works in most modes).
The functions from the ‘htype’ class may be applied to any Hyperbole types, if needed.
The following subsections explain the specifics of Hyperbole type definitions which are beyond standard practice for Emacs Lisp programming. See the definitions of the standard types in hactypes.el and hibtypes.el for examples.
| • Creating Action Types: | ||
| • Creating Implicit Button Types: |
Next: Creating Implicit Button Types, Previous: Creating Types, Up: Creating Types [Contents][Index]
New forms of explicit buttons may be created by adding new action types to a Hyperbole environment. The file, hactypes.el, contains many examples of working action types.
An action type is created, i.e. loaded into the Hyperbole environment,
with the (defact) function (which is an alias for
(actype:create)). The calling signature for this function is
given in its documentation; it is the same as that of (defun)
except that a documentation string is required. An interactive
calling form is also required if the action type has formal parameters
and is to be used in explicit or global button definitions. Implicit
buttons never use an action type’s interactive form; however, it is
good practice to include an interactive form since the type creator
cannot know how users may choose to apply the type.
An action type’s parameters are used differently than those of a function being called. Its interactive calling form is used to prompt for type-specific button attributes whenever an explicit button is created. The rest of its body is used when a button with this action type is activated. Then the button attributes together with the action type body are used to form an action that is executed in response to the button activation. The action’s result is returned to the action caller unless it returns ‘nil’, in which case ‘t’ is returned to the caller to ensure that it registers the performance of the action.
An action type body may perform any computation that uses Emacs Lisp and Hyperbole functions.
The interactive calling form for an action type is of the same form as
that of a regular Emacs Lisp function definition (see the
documentation for the Emacs Lisp (interactive) form
or see Code Characters for ’interactive’ in the GNU Emacs Lisp Reference Manual. It may additionally use
Hyperbole command character extensions when the form is given as a
string. Each such extension character must be preceded by a
plus sign, ‘+’, in order to be recognized, since such characters
may also have different standard interactive meanings.
The present Hyperbole extension characters are:
+IPrompts with completion for an existing Info (filename)nodename.
+KPrompts for an existing kcell identifier, either a full outline level identifier or a permanent idstamp.
+LPrompts for a klink specification. See the documentation for the function
(kcell-view:reference) for details of the format of a klink.
+MPrompts for a mail message date and the filename in which it resides. The mail parameters prompted for by this character code may change in the future.
+VPrompts for a Koutliner view specification string, with the current view spec, if any, as a default.
+XPrompts with completion for an existing Info index (filename)itemname.
Arguments are read by the functions in Hyperbole’s hargs class,
rather than the standard Lisp read functions, in order to allow
direct selection of arguments via the Action Key.
If an action type create is successful, the symbol that Hyperbole uses internally to reference the type is returned. On failure, ‘nil’ is returned so that you may test whether or not the operation succeeds.
Once you have defined an action type within your present Hyperbole environment, you can create new explicit buttons which use it. There is no explicit button type beyond its action type, so no other work is necessary.
Call (actype:delete) to remove an action type from a Hyperbole
environment. It takes a single parameter which should be the same type
symbol used in the type definition call (not the Hyperbole symbol
returned by the call).
Previous: Creating Action Types, Up: Creating Types [Contents][Index]
Implicit buttons leverage the same action types used by explicit and global buttons but each carries an additional implicit button type that defines the contexts in which it is active, e.g. major modes or surrounding text. Once an implicit button type definition is loaded into Hyperbole, the Action and Assist Keys automatically recognize all buttons of that type. The Action Key activates the buttons and the Assist Key summarizes their behavior and attributes. With a single definition, you can bring your text to life, activating implicit hyperbuttons in thousands of documents with no other effort.
There are three ways to create new implicit button types; the first two are meant to allow non-programmers to extend Hyperbole with simplified types.
The first is very simple but can create only link buttons with a specific textual form, i.e. <action-type button-text>.
The second is also limited to link buttons and requires regular expression knowledge; it allows for any string or regular expression button delimiters and regular expression or function link specifications.
The third requires ELisp programming knowledge but can create any implicit button type.
The sections below examine these three implicit button type creation techniques.

| • Implicit Button Link Types: | ||
| • Programmatic Implicit Button Types: |
Next: Implicit Button Link Types, Previous: Creating Implicit Button Types, Up: Creating Implicit Button Types [Contents][Index]
The simplest way to create a new implicit link type (from which any number of buttons can be recognized within text) is to create an action button link type.
A call to the defal macro of the form:
(defal TYPE LINK-EXPR &optional DOC)
will create a Hyperbole action button link TYPE (an unquoted symbol)
whose buttons always take the form of: <TYPE link-text> where
link-text is substituted into LINK-EXPR as grouping 1 (wherever
%s or \\1 is found) to form the link referent that is displayed for
each button. Hyperbole automatically creates a doc string for the
type but you can override this by providing an optional DOC string.
When the Action Key is pressed in a buffer between the start and end delimiters and the text in-between matches to TEXT-REGEXP, then the button is activated and does one of four things with LINK-EXPR:
For example, if you use Python and have a ‘PYTHONLIBPATH’ environment
variable, then pressing {C-x C-e} eval-last-sexp after
this expression:
(defal pylib "${PYTHONLIBPATH}/%s")
defines a new action button link type called ’pylib’ whose buttons take the form of:
<pylib PYTHON-LIBRARY-FILENAME>
and display the associated Python libraries (typically Python source files). Optional colon separated line and column numbers may be given as well.
Therefore an Action Key press on:
<pylib string.py:5:7>
would display the source for string.py (wherever it is installed on your system) from the Python standard library with point on the fifth line at the seventh character.
See Implicit Button Link Types, for more flexible regular expression-based link type creation. See Programmatic Implicit Button Types, for the most general implicit button type creation.
Next: Programmatic Implicit Button Types, Previous: Action Button Link Types, Up: Creating Implicit Button Types [Contents][Index]
If you understand Emacs regular expressions (see Syntax of Regular Expressions in the GNU Emacs Manual), you can create new implicit button types without understanding how to program in Emacs Lisp, aside from the instructions provided here.
A call to the defil macro of the form:
(defil TYPE START-DELIM END-DELIM TEXT-REGEXP LINK-EXPR
&optional START-REGEXP-FLAG END-REGEXP-FLAG DOC)
will create a new Hyperbole implicit button link TYPE (an unquoted symbol), recognized in a buffer via START-DELIM and END-DELIM (strings) and the TEXT-REGEXP pattern between the delimiters. With optional START-REGEXP-FLAG true, START-DELIM is treated as a regular expression. Similarly, a true value of END-REGEXP-FLAG treats END-DELIM as a regular expression. Hyperbole automatically creates a doc string for the type but you can override this by providing an optional DOC string.
When the Action Key is pressed in a buffer between the start and end delimiters and the text in-between matches to TEXT-REGEXP, then the button is activated and does one of four things with LINK-EXPR:
Prior to activation, for the first three kinds of LINK-EXPR, a
replace-match is done on the expression to generate the
button-specific referent to display. Thus, either the whole button
text (‘\\&’) or any numbered grouping from TEXT-REGEXP,
e.g. ‘\\1’, may be referenced in the LINK-EXPR to form the
link referent.
Here is a sample use case. Let’s create a button type whose buttons perform a grep-like function over a current repo’s git log entries. The buttons use this format: [<text to match>].
The following defines the button type called search-git-log with a
a key series action surrounded by braces:
(defil search-git-log "[<" ">]" ".*" "{M-: (hypb:fgrep-git-log \"\\&\") RET}")
or this simpler version skips the explicit text substitution (\\\\&) and instead uses the function that takes the button text as an argument:
(defil search-git-log "[<" ">]" ".*" #’hypb:fgrep-git-log)
Place point after one of the above expressions and evaluate it with
{C-x C-e} eval-last-sexp to define the implicit button
type. Then if you have cloned the Hyperbole repo and are in a
Hyperbole source buffer, an Action Key press on a button of the form:
;; [<test release>]
will display one line per commit whose change set matches ’test release’. An Action Key press on any such line will then display the commit changes.
If you don’t mind extra text for every button, you could instead use Action Buttons of the form: <hypb:fgrep-git-log "string"> to do the same thing without any special definitions.
Previous: Implicit Button Link Types, Up: Creating Implicit Button Types [Contents][Index]
An implicit button type is created or loaded via the (defib)
function (which is an alias for (ibtype:create)). The calling
signature for this function is given in its documentation; it is the
same as that of (defun), but with a number of constraints. The
parameter list should always be empty since no parameters will be used.
A documentation string is required; it is followed by the body of the
type.
The body of an implicit button type is a predicate which determines
whether or not point is within an implicit button of the type. If
not, the predicate returns ‘nil’. If the type is delimited,
Hyperbole automatically sets up to flash the button when activated.
Action invocations have the form: (hact 'actype &rest
actype-arguments) where actype is a Hyperbole action type
symbol or an Emacs Lisp function name or lambda;
actype-arguments are the arguments fed to the action invocation
when an implicit button of the type is activated.
It is imperative that all actions (non-predicate code) be invoked
through the (hact) function or your ibtypes will not work
properly. (Hyperbole first tests to see if any ibtype matches the
current context before activating any type, so it ensures that
(hact) calls are disabled during this testing.) Any action
types used in the definition of an implicit button type may be created
before or after the definition, but obviously, must be defined before
any implicit buttons of the given type are activated; an error will
result, otherwise.
If an implicit button type create is successful, the symbol that Hyperbole uses internally to reference the type is returned. On failure, ‘nil’ is returned so that you may test whether or not the operation succeeds. Implicit button type names and action type names may be the same without any conflict. In fact, such naming is encouraged when an implicit button type is the exclusive user of an action type.
Call (ibtype:delete) to remove an implicit button type from a
Hyperbole environment. It takes a single parameter which should be the
same type symbol used in the type definition call (not the Hyperbole
symbol returned by the call). This will not delete the action type used
by the implicit button; that must be done separately.
By default, a request for help on an implicit button will display the
button’s attributes in the same manner as is done for explicit
buttons. For some implicit button types, other forms of help will be
more appropriate. If an Emacs Lisp function is defined whose name is
formed from the concatenation of the type name followed by
‘:help’, e.g. my-ibtype:help, it is used as the
assist-action whenever the Assist Key is pressed, to respond to
requests for help on buttons of that type. Any such function should
take a single argument of an implicit button construct. (This is what
(ibut:at-p) returns when point is within an implicit button
context). Remember that the standard help for buttons with custom
help functions is still available with {C-h A} for the Action Key
and {C-u C-h A} for the Assist Key.
To programmatically query implicit buttons for their attributes, use the functions from the ‘hbut’ and ‘hattr’ classes. See the hib-kbd.el file for an example of a custom help function.

Next: Operational and Storage Formats, Previous: Explicit Button Technicalities, Up: Explicit Button Technicalities [Contents][Index]
Hyperbole uses a normalized form of button labels called button keys (or
label keys) for all internal operations. See the documentation for the
function (hbut:label-to-key) for details of the normalization
process. The normalized form permits Hyperbole to recognize buttons that
are the same but whose labels appear different from one another, due to
text formatting conventions. For example, all of the following would
be recognized as the same button.
<(fake button)> <( fake button)> Pam> <(fake Pam> button)> ;; <(fake ;; button)> /* <( fake */ /* button )> */
The last three examples demonstrate how Hyperbole ignores common fill
prefix patterns that happen to fall within the middle of a button label
that spans multiple lines. As long as such buttons are selected with
point at a location within the label’s first line, the button will be
recognized. The variable hbut:fill-prefix-regexps holds the list
of fill prefixes recognized when embedded within button labels. All
such prefixes are recognized (one per button label), regardless of the
setting of the Emacs variable, fill-prefix, so no user
intervention is required.
Next: Programmatic Button Creation, Previous: Button Label Normalization, Up: Explicit Button Technicalities [Contents][Index]
Hyperbole uses a terse format to store explicit buttons and a more
meaningful one to show users and to manipulate during editing. The
terse format consists solely of button attribute values whereas the edit
format includes an attribute name with each attribute value. A button
in edit format consists of a Lisp symbol together with its attribute list
which holds the attribute names and values. In this way, buttons may be
passed along from function to function simply by passing the symbol to
which the button is attached. Most functions utilize the pre-defined
hbut:current symbol by default to store and retrieve the last
encountered button in edit format.
The ‘hbdata’ class handles the terse, stored format. The ‘hbut’, ‘ebut’, and ‘ibut’ classes work with the name/value format. This separation permits the wholesale replacement of the storage manager with another, with any interface changes hidden from any Hyperbole client programming.
Previous: Operational and Storage Formats, Up: Explicit Button Technicalities [Contents][Index]
A common need when developing with Hyperbole is to create or to modify explicit buttons without user interaction. For example, an application might require the addition of an explicit summary button to a file for each new mail message a user reads that contains a set of keywords. The user could then check the summary file and jump to desired messages quickly.
The Hyperbole class ‘ebut’ supports programmatic access to explicit buttons. Examine it within the hbut.el file for full details.
The simplest way to create explicit buttons programmatically is to
call ebut:program. This generates an explicit button at point
from LABEL, ACTYPE (action type) and any optional ACTYPE ARGS.
It inserts the LABEL text at point surrounded by <( )> delimiters, adding any
necessary instance number of the button after the LABEL. ACTYPE may
be a Hyperbole action type name (from defact) or an Emacs Lisp
function, followed by a list of arguments for the actype, aside from
the button LABEL which is automatically provided as the first argument.
For interactive explicit creation, use hui:ebut-create instead.
The documentation for (ebut:create) explains the set of
attributes necessary to create an explicit button. For operations over
the whole set of buttons within the visible (non-narrowed) portion of a
buffer, use the (ebut:map) function.
Similarly, gbut:ebut-program programmatically adds global explicit
buttons at the end of the personal button file.
Next: Embedding Hyperbole, Previous: Explicit Button Technicalities, Up: Developing with Hyperbole [Contents][Index]
A powerful use of implicit button types is to provide a Hyperbole-based interface to external systems. The basic idea is to interpret patterns output by the application as implicit buttons.
See the hsys-* files for examples of how to do this. Encapsulations are provided for the following systems (the systems themselves are not included with Hyperbole):
The world-wide web system originally developed at CERN, that now spans the Internet universe. This is automatically loaded by Hyperbole so that a press of the Action Key follows a URL.
Previous: Encapsulating Systems, Up: Developing with Hyperbole [Contents][Index]
The standard Hyperbole user interface has purposely been separated from the Hyperbole backend to support the development of alternative interfaces and the embedding of Hyperbole functionality within other system prototypes. The Hyperbole backend functionality that system developers can make use of is called its Application Programming Interface (API). The API may be used to make server-based calls to Hyperbole when Emacs is run as a non-interactive (batch) process, with its input/output streams attached to another process.
The public functions and variables from the following files may be considered the present Hyperbole API:
hact.el, hargs.el, hbmap.el, hbut.el, hhist.el, hmail.el, hmoccur.el, hpath.el, htz.el, hypb.el, hyrolo.el, hyrolo-logic.el, hywconfig.el and set.el.
Note when looking at these files, that they are divided into sections that separate one data abstraction (class) from another. A line of dashes within a class separates public parts of the class from the private parts that follow the line.
This API does not include the Hyperbole Koutliner, as it has been designed for interactive use, rather than programmatic extensibility. You are welcome, however, to study its code, below the hyperbole-${hyperb:version}/kotl/ directory.
Next: Setup, Previous: Developing with Hyperbole, Up: Top [Contents][Index]
Concepts pertinent to operational usage of Hyperbole are defined here. See Glossary in the GNU Emacs Manual, if any emacs-related terms are unfamiliar to you.
Emacs extension package that labels windows with letters and allows quick keyboard selection or other operations on a specific window. Hyperbole extends this with a number of additional commands like throw a buffer to a window or replace a windows’s contents. See Keyboard Drags.
An executable behavior associated with a Hyperbole button. Links are a specific class of actions which display existing entities, such as files. See also Action Type.
An implicit button that uses a universal button syntax delimited by <angle brackets> to invoke any available Hyperbole action type or Emacs Lisp function. Alternatively, if it is an Emacs Lisp variable name, its action is to display the variable value.
See Smart Key.
Emacs Lisp commands that specify Hyperbole button behaviors. Action types contain zero or more arguments which must be given values for each button with which they are associated. An action type together with a set of values is an action. Actype is a synonym for action type.
Internally, Hyperbole defines its own namespace for action types
defined with its defact macro by prefixing them with
ibtypes::. Symbols with this prefix are regular Emacs Lisp
commands.
A request to a Hyperbole button to perform its action. Ordinarily the user presses a key which selects and activates a button.
A button-specific value fed to a Hyperbole type specification when the button is activated.
See Smart Key.
A named parameter slot associated with a category or type of Hyperbole button. An attribute value is typically specific to a particular button instance.
The Augment system, originally named NLS, was a pioneering research and production system aimed at augmenting human intellect and group knowledge processing capabilities through integrated tools and organizational development strategies. This approach led to the invention of much of interactive computing technology decades ahead of other efforts, including: the mouse, chord keyboards, screen windows, true hypertext, outline processors, groupware, and digitally signed documents. See References, which cites several Douglas Engelbart papers on the subject. The Koutliner demonstrates a few of the concepts pioneered in Augment.
An Emacs buffer is an editable or viewable text, possibly with special formatting such as an outline or table. It may also be attached to a process, receiving and updating its text as the process handles changing information.
A selectable Hyperbole construct which performs an action. A button consists of a set of attributes that includes: a textual label, a category, a type and zero or more arguments. Explicit buttons also have creator, create time, last modifier, and last modifier time attributes.
Buttons provide user gateways to information. Users see and interact with button labels; the rest of the button attributes are managed invisibly by Hyperbole and displayed only in response to user queries.
See Activation.
See Attributes.
Lists of button attribute values explicitly saved and managed by Hyperbole. One list for each button created by Hyperbole.
A per-directory file named HYPB that may be used to store any buttons that link to files within the directory. It may be displayed via a menu selection whenever a user is within the directory.
A per-user file named HYPB that stores all global buttons for the user and any other buttons used to navigate to other information spaces. It may be displayed via a menu selection at any time.
A normalized form of a button label used internally by Hyperbole.
A text string that visually indicates a Hyperbole button location and that serves as its name and unique identifier. Within a buffer, buttons with the same label are considered separate views of the same button and so behave exactly alike. Since button labels are simply text strings, they may be embedded within any text to provide non-linear information or operational access points.
The act of designating a Hyperbole button upon which to operate. Use the Action Key to select a button.
A class of Hyperbole buttons: implicit, explicit or global.
See Kcell.
The set of koutline cells which share a common parent cell and thus, are one level deeper than the parent.
A group of functions and variables with the same prefix in their names, used to provide an interface to an internal or external Hyperbole abstraction.
An Emacs extension package that provides asynchronous search and narrow wrappers around common search commands like grep, ripgrep, find and locate.
Hyperbole uses this package to provide convenience commands for line-oriented searches.
Searches Org Roam notes in org-roam-directory with consult.
Searches Org notes in org-directory with consult.
A programmatic or positional state recognized by Hyperbole. We speak of Smart Key and implicit button contexts. Both are typically defined in terms of surrounding patterns within a buffer, but may be defined by arbitrary Emacs Lisp predicates.
See Screen.
The contexts in which an implicit button type may be found, i.e. where its predicate is true.
A mouse button press in one location and following release in another location.
An Action Button that links to an explicit button. It begins with <elink: followed by an explicit button label, an optional ebut file and ends with a closing >.
See Hyperbole Environment.
A button created and managed by Hyperbole, associated with a specific action type. By default, explicit buttons are delimited like this ‘<(fake button)>’. Direct selection is used to operate upon an explicit button.
Flymake is an Emacs library that lints your code in the background.
It provides flymake-minor-mode for source buffers and
flymake-diagnostics-buffer-mode for listing the linter issues
for a given source buffer. Hyperbole extends this library with Smart
Key jump and display issue contexts as well as a key map of commands
in source buffers to support removal of flymake issues without having
to jump to the issue listing buffer.
An Emacs frame displays one or more Emacs windows and widgets (menubars, toolbars, scrollbars). Under a graphical window system, this is a single window system window. On a dumb terminal, only one frame is visible at a time as each frame generally fills the whole terminal display, providing a virtual screen capability. Emacs windows exist within a frame.
A Hyperbole button which is accessed by name rather than direct
selection. Global buttons are useful when one wants quick access to
actions such as jumping to common file locations or for performing
sequences of operations. One need not locate them since they are
always available by name, with full completion offered. All global
buttons are stored in the file returned by the function call,
(gbut:file), and may be activated with the Action Key when
editing this file. By default, this is the same as the user’s
personal button file.
An Action Button that links to a global button. It begins with <glink: followed by a global button label and then a closing >.
See Button File, personal and Global Button.
See Windows Grid.
The maximum length of a button label is limited by the variable
hbut:max-len. If 0, there is no limit and searches for button
end delimiters can go as far as the end of the buffer. Use the
function, (hbut:max-len), to read the proper value.
An Emacs extension package that provides asynchronous search and narrow
wrappers around many Emacs commands. Hyperbole optionally utilizes this
together with the org-rifle package to interactively search the
HyRolo. Use M-x hyrolo-helm-org-rifle to search your HyRolo file
list with these packages.
A variable that permits customization of an existing function’s
operation without the need to edit the function’s code. See also the
documentation for the function (run-hooks).
HyControl, the Hyperbole window and frame control manager, offers fast, single key manipulation of window and frame creation, deletion, sizing, position and face zooming (enlarging/shrinking).
The flexible, programmable information management and viewing system documented by this manual. It utilizes a button-action model and supports hypertextual linkages. Hyperbole is all things to all people.
A programmatic context within which Hyperbole operates. This includes the set of Hyperbole types defined and the set of Hyperbole code modules loaded. It does not include the set of accessible buttons. Although the entire Emacs environment is available to Hyperbole, we do not speak of this as part of the Hyperbole environment.
A text or group of texts which may be explored in a non-linear fashion through associative linkages embedded throughout the text. Instead of simply referring to other pieces of work, hypertext references when followed actually take you to the works themselves.
HyRolo, the Hyperbole record/contact manager, provides rapid lookup of multi-line, hierarchically ordered free form text records. It can also lookup records from Google/GMail Contacts and the Big Brother DataBase (BBDB) package.
An Action Button that links to another implicit button. It begins with <ilink: followed by an implicit button label, an optional ibut file and ends with a closing >.
A button recognized contextually by Hyperbole. Such buttons contain no button data but may have an optional preceding label that looks like this: ‘<[label]>’. See also implicit button type.
A specification of how to recognize and activate implicit buttons of a specific kind. Implicit button types often utilize structure internal to documents created and managed by tools other than Hyperbole, for example, programming documentation. Ibtype is a synonym for implicit button type. See also system encapsulation.
Internally, Hyperbole defines its own namespace for ibtypes defined
with its defib macro by prefixing them with ibtypes::.
Symbols with this prefix are invokable Emacs Lisp functions.
InfoDock is an older integrated productivity toolset for software engineers and knowledge workers built atop XEmacs; it is no longer maintained or updated, though many of its packages can be used with GNU Emacs. An older version from 1999 may be found at infodock.sf.net.
InfoDock has much of the power of GNU Emacs, but with an easier to use and more comprehensive menu-based user interface. Most objections people raise to using emacs have already been addressed in InfoDock. InfoDock is meant for people who prefer a complete, pre-customized environment in one package.
A colon prefaced number appended to the label of a newly created button when the button’s label duplicates the label of an existing button in the current buffer. This number makes the label unique and so allows any number of buttons with the same base label within a single buffer.
See also https://tkf.github.io/emacs-jedi/latest/.
Jedi is a Emacs package for Python completion, definition and documentation lookup.
A single sequence of keys that can invoke an Emacs command.
A series of one or more Emacs key sequences delimited by braces that Hyperbole processes when activated as an implicit button, as if the keys were typed in by the user.
A reference to a Koutline cell. Such a reference may be:
12 - a whole number representing a permanent idstamp
or any of the following string forms:
1 or 1b - relative id, augment style 1.2 - relative id, legal style 012 - permanent idstamp 1a=012 - both relative and permanent ids (in that order) separated by = |viewspec - a viewspec setting, rather than a cell reference
Optionally, any of these id forms (or the relative form) may be followed by zero or more whitespace characters, a | and some view specification characters. See View Specs.
An angle bracket, <>, delimited implicit button type that displays a koutline cell referent at the top of a window. The link may be of any of the following forms:
< pathname [, kcell-ref] > < [-!&] pathname > < @ kcell-ref >
See the above definition of Kcell Ref for kcell-ref formats.
A hierarchically ordered grouping of cells which may be stored as a file and viewed and edited as an outline.
Koutliner, the Hyperbole outliner, is a powerful autonumbering outliner with permanent hypertext anchors for easy hyperlinking and view specs for rapid outline view alteration.
Cells or kcells are elements within koutlines. Each cell may contain textual and graphical contents, a relative identifier, a permanent identifier and a set of attributes such as the user who created the cell and the time of creation. See also Koutliner.
A reference from a Hyperbole button to an existing (non-computed) entity. The referenced entity is called a referent. Links are a subset of the types of actions that Hyperbole buttons support.
See Button File, local.
The one line window at the bottom of a frame where messages and prompts are displayed.
A Hyperbole menu displayed in the minibuffer window. Each menu item within a minibuffer menu begins with a different letter that can be used to invoke the item (case doesn’t matter). Items that display other menus end with a forward slash, ‘/’.
See Smart Key.
See Augment.
See Link or Cell.
See also https://www.gnu.org/software/oo-browser.
The GNU OO-Browser is a multi-windowed, interactive object-oriented class browser similar in use to the well-known Smalltalk browsers. It runs inside Emacs. It is unique in a number of respects foremost of which is that it works well with most major object-oriented languages in use today. You can switch from browsing in one language to another in a few seconds. It provides both textual views within an editor and graphical views under the X window system and Windows. It includes support for C, C++, Common Lisp and its Object System (CLOS), Eiffel, Java, Objective-C, Python and Smalltalk.
Hyperbole provides the mouse support for the OO-Browser, providing Smart Keys that utilize the OO-Browser’s capabilities both when it is displayed on screen and when editing code.
A built-in Emacs mode for outlining, note taking and scientific publishing. Hyperbole simplifies access to a number of its features and integrates its own hypermedia capabilities with those of Org mode. Hyperbole can display the referent of any Org Id. See Smart Key - Org Mode.
An Emacs extension package that inserts ids into Org mode files and indexes them within a Sqlite database for rapid note taking and lookup by title. Hyperbole can display the referent of any Org Roam Id and provides full-text searching of Org Roam nodes utilzing the interactive grep commands from the Consult extension package.
See Koutline.
Any koutline cell which has children.
The previous same level koutline cell with the same parent.
A boolean (‘nil’ = false, non-nil = true = ‘t’) Lisp expression typically evaluated as part of a conditional expression. Implicit button types contain predicates that determine whether or not a button of that type is to be found at point.
See Link.
A file or directory on a system not shared within the local area network. The built-in Emacs library, Tramp, handles remote pathnames and Hyperbole uses it to enable viewing and editing of remote paths of the form: /<protocol>:<user>@<host>:<path> as well as web URLs. Use the Cust/Find-File-URLs menu option to enable this feature.
See HyRolo.
A koutline cell which has cells below it at lower outline levels. All such cells share the same root cell.
The total display area available to Emacs frames. This may consist of multiple physical monitors arranged into a single virtual display. Screen edges are thus the outer borders of the virtual display.
A context-sensitive key used within Hyperbole and beyond. There are two Smart Keys, the Action Key and the Assist Key. The Action Key activates Hyperbole buttons and scrolls the current buffer line to the top of the window when pressed at the end of a line.
The Assist Key shows help for Hyperbole buttons and scrolls the current line to the bottom of the window when pressed at the end of a line.
The {C-h h d s} Doc/SmartKeys menu item displays a full summary of Smart Key capabilities. See Smart Keys, for complete details.
Smart Menus are an older in-buffer menu system that work on dumb terminals and pre-dated Emacs’ own dumb terminal menu support. They are included with InfoDock (which is no longer maintained) and are not available separately. They are not a part of Hyperbole and are not necessary for its use but are still supported by the Smart Keys.
The buffer or file within which a Hyperbole button is embedded.
All of the cells in a koutline which share the same root cell, excluding the root cell.
The next same level koutline cell which follows the current cell and shares the same parent.
Use of Hyperbole to provide an improved or consistent user interface to another system. Typically, implicit button types are defined to recognize and activate button-type constructs managed by the other system.
A remote file access library built-in to Emacs. It uses secure transfer and works with many types of hosts. It allows you to use remote pathnames that are accessible via Internet protocols just like other pathnames, for example when finding a file. Hyperbole recognizes pathnames of the form, /<protocol>:<user>@<host>:<path> and web URLs.
The set of cells in a koutline that share a common root cell, including the root cell.
A Universal Resource Locator specification used on the World-Wide web to access documents and services via a multiplicity of protocols.
A perspective on some information. A view can affect the extent of the information displayed, its format, modes used to operate on it, its display location and so forth.
A terse string that specifies a particular view of a koutline or a link referent. If a view spec is active for a buffer, the view spec appears within the modeline like so, <|view spec>. See View Specs.
An Emacs window displays a single Emacs buffer within a single frame. Frames may contain many windows.
A feature of HyControl invoked with {@} which creates, lays out and populates a grid of a specified size of new Emacs windows, e.g. 4 rows by 3 columns, each displaying a different buffer chosen by a set of user specifiable filters or from a list.

Once you have Emacs set up at your site, the stable, released version of GNU Hyperbole may be installed by using the Emacs Package Manager. If you are not familiar with it, see Packages in the GNU Emacs Manual. Releases are very rare and the in-development branch may be many months and features ahead, so you may want to consider using either the Elpa In-Development or Git In-Development installation instead.
If you have Hyperbole installed and simply want to upgrade it, invoke the Emacs Package Manager with {M-x list-packages RET}, then use the {U} key followed by the {x} key to upgrade all out-of-date packages, Hyperbole among them. Then skip the text below and move on to the next section, see Invocation.
Otherwise, to download and install the Hyperbole package, you should add several lines to your personal Emacs initialization file, ~/.emacs. (For further details, see The Emacs Initialization File in the GNU Emacs Manual).

The Elpa In-Development package pulls from the latest Hyperbole development branch tip and does not require installation of any new package manager software. Since Hyperbole is a mature package, this is usually fine to use and update on a day-to-day basis. But new features are tested on this branch and once in awhile it may break for a short time before a fix is pushed. With this branch you’ll be able to submit bug reports and feature requests but will not be able to submit pull requests for changes to the developers; use the Git In-Development Package instead for that.

If you are old-school, don’t like package managers, and prefer doing everything by hand, then you can obtain Hyperbole from a tarball:
Download either:
ftp://ftp.gnu.org/gnu/hyperbole/ or http://ftpmirror.gnu.org/hyperbole/, which will find the closest mirror of the GNU ftp site and show it to you.
Then decompress and unpack the archive to a directory of your choosing. Move into the hyperbole-<version>/ directory and execute the following Posix shell command:

Major Hyperbole user options may be set from the Customize submenu below the Hyperbole menubar menu, as seen here.
Alternatively, the minibuffer-based menu, Cust/ may be used.
Generally, you should not need to change anything other than these options. However, if you like to customize your environment extensively, there are many additional Hyperbole customization options that may be changed with the Emacs customization interface, see Easy Customization Interface in the GNU Emacs Manual. When you save any changes within this interface, the changes are saved permanently to your personal Emacs initialization file and are available in future Emacs sessions.
Use Cust/All-Options {C-h h c a} to display an expandable tree of customizable Hyperbole options. Hyperbole’s customizations are further grouped into several sub-categories, one for the Koutliner, one for the HyRolo, etc. You can select either an entire category or a specific option and they will appear in another window for editing. Simply follow the instructions on screen and then press the “Apply and Save” button to make any changes permanent.
If you know the name of the option you want to edit, you can edit it at any time without going through the tree of options. Use {M-x customize-variable RET} and then type the name of the variable and press RET to edit it.
The following sections discuss the customization options most likely to be of interest to users.

Next: Internal Viewers, Previous: Customization, Up: Customization [Contents][Index]
Hyperbole lets you control where link referents are displayed. It also permits setting a specific Emacs function or external program to display them. There are four categories of referents, each with its own customizable display setting, listed in decreasing order of priority. All of these variables are defined within hpath.el.
Referent Category Variable Setting ====================================================================== Internal Image Display hpath:native-image-suffixes Internal Custom Display hpath:internal-display-alist External Display hpath:external-display-alist Internal Standard Display hpath:display-where
Continue reading the next sections for information on how referents are displayed internally and externally.
Next: External Viewers, Previous: Referent Display, Up: Customization [Contents][Index]
When given a filename to display, Hyperbole first checks if its suffix
is matched by hpath:native-image-suffixes. If so and if the
function image-mode is defined, it uses that mode together with
the value of hpath:display-where to display the image within an
Emacs buffer.
If no match is found, the hpath:internal-display-alist variable
is checked for a filename match. Its value is an association list
whose elements are (<file-name-regular-expression>
. <function-of-one-arg>) pairs. Any path whose name matches
a <file-name-regular-expression> will be displayed by calling the
associated <function-of-one-arg> with the filename as the argument.
The first regular expression that matches each filename is the one
used. This can be used to format raw data files for convenient
display.
By default, this setting handles the following types of files:
Major audio format files are played with the play-sound-file command.
Files with a .info suffix (may also be compressed) are displayed in the Info browser.
Files with an .rdb suffix are displayed as relational databases using the RDB package available with InfoDock.
Links to standard files, those which don’t match any special referent
category described earlier, are displayed in an Emacs window specified
by the hpath:display-where setting. It may be changed with the
Cust/Referents {C-h h c r} menu.
Available options are:
Display in the selected window of another existing frame
Display in the selected (current) window
Display in the selected window of another existing frame, deleting its other windows
Display in a new single window frame
Display in another, possibly new window of the selected frame (this is the default)
Display in a window of the selected frame and delete its other windows
Alternatively, you can use the Hyperbole menubar menu as shown here:
See External Viewers, for instructions on associating filenames with external, window-system specific viewers.
Next: Link Variable Substitution, Previous: Internal Viewers, Up: Customization [Contents][Index]
If you use Hyperbole under a window system,
the hpath:get-external-display-alist function in hpath.el
supports hyperlinks that open files using external, non-Emacs tools, e.g.
a pdf reader or a vector graphics viewer.
The value returned by hpath:get-external-display-alist is determined
based on the window system supported by the current frame and the version
of Emacs in use. This value is an association list whose elements are
(<file-name-regular-expression> . <viewer-program-or-list>) pairs. Any
path whose name matches a <file-name-regular-expression> will be
displayed using the corresponding viewer-program or the first
viewer-program found on the system from a list of programs. If a
<viewer-program> entry contains a ‘%s’ string, the filename to
display is substituted at that point within the string.
Otherwise, the filename is appended to the <viewer-program>
entry. Alternatively, the viewer-program may be a Lisp function that
takes a single filename argument.
The association lists used by this function are stored in variables
for each available window system: hpath:external-display-alist-macos,
hpath:external-display-alist-mswindows, and
hpath:external-display-alist-x. Examine and modify these
values to suit your needs.
Part of these values for each operating system come from the
variable, hpath:external-file-suffixes’, which holds a regular
expression of operating system independent file suffixes to open outside
Emacs.
Next: Web Search Engines, Previous: External Viewers, Up: Customization [Contents][Index]
Another option to consider modifying is hpath:variables. This
option consists of a list of Emacs Lisp variable names, each of which
may have a pathname or a list of pathnames as a value. Whenever a
Hyperbole file or directory link button is created, its pathname is
compared against the values in hpath:variables. The first
match found, if any, is selected and its associated variable name is
substituted into the link pathname, in place of its literal value.
When a link button is activated, potentially at a different site,
Hyperbole replaces each variable in the link pathname with the first
matching value from this list to recreate the literal pathname.
Environment variables and Emacs Lisp variables delimited
by \"${variable-name}\" are also replaced whenever link paths are
resolved.
This permits sharing of links over wide areas, where the variable values
differ between link creator and link activator. The entire process
is wholly transparent to the user; it is explained here simply to help
you in deciding whether or not to modify the value of hpath:variables.
Next: Using URLs with Find-File, Previous: Link Variable Substitution, Up: Customization [Contents][Index]
The Find/Web menu offers quick access to major web search engines. It is typically bound to {C-c /} or if not, then {C-h h f w} is always available. Your standard web browser will be used to return the search results.
The hyperbole-web-search-alist variable controls the items in
this menu. Elements of this alist are of the form:
(<web-service-name> . <url-with-%s-parameter-or-command>). The first
capitalized character of each <web-service-name> must be unique for
minibuffer menu selection. The second part of an element is either:
a URL with an embedded %s indicating where to substitute a search term that is interactively prompted for when the menu item is activated;
or an Emacs command symbol that interactively prompts for a URL and a search term and then displays the search results.
Advanced users can change the search engines listed in the Find/Web menu with {M-x customize-variable RET hyperbole-web-search-alist RET}. Changes are automatically reflected in the Hyperbole menus once applied. Remember each search engine name must begin with a unique letter and each URL must have a %s format field indicating where to place the web search term when a search is performed.
You can change which browser is used with {C-h h c w}, the Cust/Web-Search menu. Below is the equivalent Hyperbole menubar menu.
Next: Invisible Text Searches, Previous: Web Search Engines, Up: Customization [Contents][Index]
Hyperbole always recognizes URLs within buffers when the Action Key is
pressed on them. But sometimes it is useful to enter a URL at a prompt
and have it displayed. Hyperbole can recognize s/ftp and www URLs given to
the find-file command (or any other find-file-* commands).
But because there is added overhead with this feature, it is not enabled by
default.
To enable the feature, use the Hyperbole menu item Cust/Find-File-URLs (or Find-File-Accepts-URLs on the Hyperbole/Customize pulldown menu). Either of these toggles acceptance of URLs. When enabled the string, URLs, appears in the parenthesized minor-mode section of the modeline.
To enable this feature each time you start the editor, add the
following to your personal initialization file after initializing
Hyperbole: (hpath:find-file-urls-mode 1).
Both full URLs and abbreviated ones, like www.gnu.org, are recognized. filename completion does not work with URLs; you have to type or paste in the entire URL. This feature will work only if you have the builtin Tramp Emacs Lisp package; if you don’t have Tramp, an error message will be displayed when you try to enable find-file URLs.
The web browser used to display URLs may be set with the minibuffer menu Cust/URL-Display {C-h h c u} or with this Hyperbole menubar menu.
Next: Button Colors, Previous: Using URLs with Find-File, Up: Customization [Contents][Index]
This is largely for outline modes such as the Koutliner. By default, character-by-character interactive search on {C-s} will search through invisible/hidden text, making the text temporarily visible until point moves past that hidden part. When a search match is selected, the surrounding text remains visible.
You can temporarily disable searching of hidden text by typing {M-s i} while in an incremental search. This key sequence toggles that setting and makes searches look at only visible text (or the reverse when invoked again). The setting lasts only through the current interactive search.
Previous: Invisible Text Searches, Up: Customization [Contents][Index]
When Hyperbole is run under a window system, it automatically
highlights any explicit buttons in a buffer and makes them flash when
selected. The main setting you may want change is the selection of a
color (or style) for button highlighting and button flashing. See
the hui-*-b*.el files for lists of potential colors and the
code which supports this behavior. A call
to (hproperty:cycle-but-color) in the hsettings.el file
changes the color used to highlight and flash explicit buttons.
You may also change the length of time in fractions of a second that a
button flashes by setting hproperty:but-flash-time-seconds.
Whether or not buttons are highlighted is controlled
by hproperty:but-highlight-flag, which defaults to ‘t’.
To disable highlighting, change this setting in hsettings.el or
use Hyperbole menu item, Cust/All-Options, and select the Hyperbole
Buttons group to edit its options.
If you read in a file with explicit buttons before you load Hyperbole, these buttons won’t be highlighted. Load Hyperbole and then use {M-x hproperty:but-create RET} to highlight the buttons in the current buffer.
Additionally, if hproperty:but-emphasize-flag is set to ‘t’,
then whenever the mouse pointer moves over an explicit button, it will
be emphasized in a different color or style. This emphasis is in
addition to any non-mouse-sensitive button highlighting.

This appendix covers two topics: 1. how to bind Hyperbole minibuffer menu items to global keys and 2. summaries of all of Hyperbole’s default key bindings. User-specific Hyperbole key binding customizations override Hyperbole’s defaults.
| • Binding Minibuffer Menu Items: | ||
| • Default Hyperbole Bindings: | ||
| • Testing: |
Next: Default Hyperbole Bindings, Previous: Hyperbole Key Bindings, Up: Hyperbole Key Bindings [Contents][Index]
Use {M-x hyperbole-set-key RET} to bind any global key to any Hyperbole minibuffer menu item. This command will first prompt for the key sequence you want to use to activate the menu item. Immediately after, it will display the Hyperbole top-level minibuffer menu. Simply select the item you want to bind to your key.
Next: Testing, Previous: Binding Minibuffer Menu Items, Up: Hyperbole Key Bindings [Contents][Index]
Hyperbole’s default key bindings can be viewed and edited from either the Cust/KeyBindings minibuffer menu or from the Hyperbole menubar menu as shown here:
Below are descriptions of Hyperbole’s default keyboard key bindings.
All except {C-h h} (the global key used to enable Hyperbole and
display its minibuffer menu) are bound within Hyperbole’s minor mode
keymap, hyperbole-mode-map.
Assist Key: Invoke the Assist Key in the present context.
HyControl: Control windows, frames and buffer display. This binding is made only if the key is not bound prior to initializing Hyperbole.
Search the Web: Display a minibuffer menu of web search engines. Once an engine is selected, prompt for a search term and perform the associated search.
This binding is made only if the key is not bound prior to
initializing Hyperbole; it also defers to any major-mode
binding. When needed, the Find/Web minibuffer menu item, {C-h
h f w}, will do the same thing.
Display a grid of windows in the selected frame, sized according to the prefix argument. The left digit of the argument is the number of grid rows and the right digit is the number of grid columns. Use {C-h h h} to restore the prior frame configuration.
If the argument is 0, prompt for a major mode whose buffers should be displayed first in the grid windows, then prompt for the grid size.
If the argument is < 0, prompt for a shell glob-type file pattern and display files that match the pattern in an auto-sized windows grid.
This binding is made only if the key is not bound prior to
initializing Hyperbole; it also defers to any major-mode
binding and when outline-minor-mode is active.
For further details, see the {@} key binding description in HyControl.
Drag Operation: Keyboard emulation of the start and stop of mouse drags to invoke Smart Key actions. This binding is made only if the key is not bound prior to initializing Hyperbole and if Emacs is run under a window system. If the Ace Window package is loaded, then Ace Window commands are typically bound to {M-o} instead. Then {M-o w} may be used to quickly create an implicit link button in the selected window that links to a referent in any other window chosen via the Ace Window prompt.
Hyperbole Mini Menu: Enable Hyperbole minor mode and invoke the Hyperbole minibuffer menu, giving access to many Hyperbole commands. This is bound globally. Use {C-h h X} to close the Hyperbole minibuffer menu and disable Hyperbole minor mode.
Action Key Help: Show what the Action Key will do in the current context.
Assist Key Help: Show what the Assist Key will do in the same context.
Mark Things: Mark larger and larger syntactical units in a buffer when invoked repeatedly, showing in the minibuffer the type of unit marked each time. For example, if on an opening brace at the start of a C, Java or Javascript function, this marks the whole function.
This binding is made only if the key is not bound prior to
initializing Hyperbole; it also defers to any major-mode
binding.
Delimited Thing Jump: Jump between the start and end of a delimited thing, which may be an HTML tag pair.
This binding is made only if the key is not bound prior to
initializing Hyperbole; it also defers to any major-mode
binding. See Smart Key Thing Selection, for more information.
Delimited Thing, Koutline Cell Reference or Region Copy: While Hyperbole is
active, it sets mark-even-if-inactive to nil and overrides
{M-w} with its own command, hui-kill-ring-save, which copies the
region only when it is active/highlighted. When there is no active region,
{M-w} does one of the following:
Delimited Thing, Koutline Cell Reference or Region Save to Register: This
does the same thing as {M-w} except it copies to an Emacs register
given by a letter or number rather than the kill ring. While Hyperbole is active,
it overrides {C-x r s} with its own command, hui-copy-to-register.
which copies the region only when it is active/highlighted.
The variable, hkey-init, controls whether or not any Hyperbole
key bindings are made when hyperbole-mode is active. It is set
to ‘t’ (true) by default in hyperbole.el. This setting
means all Hyperbole key bindings will be initialized when Hyperbole is
loaded. If you want to disable these bindings permanently, simply add
(setq hkey-init nil) to your ~/.emacs file prior to the
point at which you load Hyperbole; then restart Emacs. Henceforth,
you will have to choose the Hyperbole commands that you want to use
and bind those to keys.
If you ever want to temporarily disable Hyperbole key and mouse bindings,
simply toggle Hyperbole minor mode off with the hyperbole-mode
command. There is no default key binding for this command; use {M-x
hyperbole-mode RET}. Alternatively, you may select a key and bind it
as part of any setting of hyperbole-init-hook within your
personal ~/.emacs file. For example, (add-hook
'hyperbole-init-hook (lambda () (global-set-key "\C-ct" 'hyperbole-mode))).

Hyperbole includes over 200 automated test cases in the test/
subdirectory. You can run all of them by moving to the Hyperbole home
directory in a Posix shell and run make test-all or make
test to run just non-interactive tests. If any tests fail, you can
press the Action Key to see the source of the failure. Full testing is
supported under POSIX systems only.
With Hyperbole active, you can also define implicit buttons that run individual or sets of Hyperbole tests. The file hypb-ert.el contains two action link types:
hyperbole-run-test- run a single Hyperbole test by namehyperbole-run-tests- run one more tests matching a pattern Example uses with a press of the Action Key: Run the test hbut-defal-url: <hyperbole-run-test hbut-defal-url> Run the tests specified by the test selector hbut-defal: <hyperbole-run-tests hbut-defal> Run all tests: <hyperbole-run-tests t>

This appendix summarizes the specialized key bindings available when editing a koutline with Hyperbole. Each key is shown together with its command binding and the documentation for that command. Normal emacs editing keys are modified to account for the structure within outlines. An outliner command which overloads an emacs command named cmd is named kotl-mode:cmd.
kfile:write {C-x C-w}Write the current outline to FILE.
klink:create {C-c l}Insert at point an implicit link to REFERENCE.
REFERENCE should be a cell-ref or a string containing "filename, cell-ref".
See the documentation for (kcell:ref-to-id) for valid cell-ref
formats.

kotl-mode:kill-contents {C-c k}Kill contents of cell from point to cell end. With prefix ARG, kill entire cell contents.
kotl-mode:kill-line {C-k}Kill ARG lines from point.
kotl-mode:kill-region {C-w}Kill region between START and END within a single kcell. With optional COPY-P equal to t, copy region to kill ring but don’t kill it. With COPY-P any other non-nil value, return region as a string without affecting the kill ring.
If called interactively and there is no active region, copy any
delimited selectable thing at point; see the documentation for
hui:delimited-selectable-thing.
If the buffer is read-only and COPY-P is nil, the region will not be deleted but it will be copied to the kill ring and then an error will be signaled.
If a completion is active, this aborts the completion only.
kotl-mode:kill-ring-save {M-w}Copy region between START and END within a single kcell to kill ring.
kotl-mode:kill-sentence {M-k}Kill up to prefix ARG (or 1) sentences following point within a single cell.

kotl-mode:kill-word {M-d}Kill up to prefix ARG words following point within a single cell.
kotl-mode:last-sibling {C-c >}Move point to the last sibling of the present cell. Leave point at the start of the cell or at its present position if it is already within the last sibling cell.
kotl-mode:mail-tree {C-c C-@}Mail outline tree rooted at CELL-REF. Use "0" for whole outline buffer.
kotl-mode:move-after {C-c m}Move tree rooted at FROM-CELL-REF to follow tree rooted at TO-CELL-REF. If prefix arg CHILD-P is non-nil, make FROM-CELL-REF the first child of TO-CELL-REF, otherwise make it the sibling following TO-CELL-REF. With optional COPY-P, copy tree rather than moving it.
Leave point at original location but return the tree’s new start point.
kotl-mode:move-before {C-c RET}Move tree rooted at FROM-CELL-REF to precede tree rooted at TO-CELL-REF. If prefix arg PARENT-P is non-nil, make FROM-CELL-REF the first child of TO-CELL-REF’s parent, otherwise make it the preceding sibling of TO-CELL-REF. With optional COPY-P, copy tree rather than moving it.
Leave point at original location but return the tree’s new start point.
kotl-mode:newline {RET}Insert a newline. With ARG, insert ARG newlines. In Auto Fill mode, if no numeric arg, break the preceding line if it is too long.
kotl-mode:next-cell {C-c C-n}Move to prefix ARG next cell (any level) within current view.
kotl-mode:next-line {C-n}Move point to ARGth next line and return point.
kotl-mode:open-line {C-o}Insert a newline and leave point before it. With arg N, insert N newlines.

kotl-mode:previous-line {C-p}Move point to ARGth previous line and return point.
kotl-mode:promote-tree {M-TAB} or {SHIFT-TAB}Move current tree a maximum of prefix ARG levels higher in current view.
Each cell is refilled iff its no-fill attribute is nil and
kotl-mode:refill-flag is non-nil. With prefix ARG = 0, cells are
promoted up to one level and kotl-mode:refill-flag is treated as true.
kotl-mode:scroll-down {M-v}Scroll text of current window downward ARG lines; or a windowful if no ARG.
kotl-mode:scroll-up {C-v}Scroll text of current window upward ARG lines; or a windowful if no ARG.
kotl-mode:set-cell-attribute {C-c C-i}Include ATTRIBUTE VALUE with the current cell or the cell at optional POS. Replace any existing value that ATTRIBUTE has. When called interactively, display the setting in the minibuffer as confirmation.
kotl-mode:set-fill-prefix {C-x l}Set fill prefix to line up to point. With prefix arg TURN-OFF or at begin of line, turn fill prefix off.
kotl-mode:show-all {C-c C-a}Show (expand) all cells in current view. With a prefix arg, also toggle the display of blank lines between cells.
kotl-mode:show-subtreeShow subtree, ignoring root, at optional CELL-REF (defaults to cell at point).
kotl-mode:show-tree {C-c C-s}Display fully expanded tree rooted at CELL-REF.
kotl-mode:split-cell {C-c s}Split cell into two cells and move to new cell. Cell contents after point become part of newly created cell. Default is to create new cell as sibling of current cell. With optional universal ARG, {C-u}, new cell is added as child of current cell.
kotl-mode:top-cells {C-c C-t}Collapse all level 1 cells in view and hide any deeper sublevels. With a prefix arg, also toggle the display of blank lines between cells.
kotl-mode:transpose-cells {C-c t}Exchange current and previous visible cells, leaving point after both. If no previous cell, exchange current with next cell. With prefix ARG, take current cell and move it past ARG cells. With prefix ARG = 0, interchange the cell that contains point with the cell that contains mark.
kotl-mode:transpose-chars {C-t}Interchange characters around point, moving forward one character. With prefix ARG, take character before point and drag it forward past ARG other characters (backward if ARG negative). If no prefix ARG and at end of line, the previous two characters are exchanged.
kotl-mode:transpose-lines {C-x C-t}Exchange current line and previous line, leaving point after both. If no previous line, exchange current with next line. With prefix ARG, take previous line and move it past ARG lines. With prefix ARG = 0, interchange the line that contains point with the line that contains mark.
kotl-mode:transpose-words {M-t}Interchange words around point, leaving point after both words.

killed OR yanked. Put point at end, and set mark at beginning.
With just C-u as argument, same but put point at beginning (and mark at end).
With argument N, reinsert the Nth most recently killed stretch of killed
text.
See also the command, (kotl-mode:yank-pop).
kotl-mode:yank-pop {M-y}Replace just-yanked stretch of killed text with a different stretch.
This command is allowed only immediately after a (yank) or a
(yank-pop). At such a time, the region contains a stretch of
reinserted previously-killed text. (yank-pop) deletes that text
and inserts in its place a different stretch of killed text.
With no argument, the previous kill is inserted. With argument N, insert the Nth previous kill. If N is negative, this is a more recent kill.
The sequence of kills wraps around, so that after the oldest one comes the newest one.
kotl-mode:zap-to-char {M-z}Kill up to and including prefix ARGth occurrence of CHAR. Goes backward if ARG is negative; error if CHAR not found.
kview:set-label-separator {C-c M-l}Set the LABEL-SEPARATOR (a string) between labels and cell contents for the current kview. With optional prefix arg SET-DEFAULT-P, the default separator value used for new outlines is also set to this new value.
kview:set-label-type {C-c C-l}Change kview’s label display type to NEW-TYPE, updating all displayed labels.
See documentation for the kview:default-label-type variable,

This appendix documents Hyperbole’s context-sensitive Smart Key operations. It is quite extensive and is meant for reference rather than sequential reading. See Smart Keys, for a description of the Smart Keys. That section also describes how to get context-sensitive Smart Key help, with which you can explore Smart Key operation bit by bit.
What a Smart Key does depends on the context in which it is used. Smart Key operations are context-sensitive. Contexts are defined by logic conditionals, e.g. when depressed here, if this is true, etc. Each Smart Key context is listed in the order in which it will be checked. The first matching context is always the one applied. Within each context, the actions performed by the Action and Assist Keys are given.

The contexts and actions in this section, like drags and modeline clicks, apply only if you have mouse support within Hyperbole. The Smart Key operations in Smart Keyboard Keys, apply to both mouse and keyboard Smart Key usage.
The following section documents what the Smart Mouse Keys do in each context, with the contexts listed in decreasing order of priority, i.e. the first context to match is the one that is used. If no matching mouse key context is found, then the keyboard key contexts are searched in order.
Next: Thing Selection, Previous: Smart Mouse Keys, Up: Smart Mouse Keys [Contents][Index]
When clicked within an inactive minibuffer:
ACTION KEY
The Hyperbole minibuffer menu is displayed for selection, by default.
The variable action-key-minibuffer-function controls this behavior.
ASSIST KEY
The buffer, window and frame jump menu is displayed for selection, by default.
You can jump to buffers categorized by major mode, jump to windows by buffer
name, or to frames by name. Manage your windows and frames quickly with this
menu as well. This is the same menu that a click in a blank area of the
modeline displays by default since they are typically so close together. The
variable assist-key-minibuffer-function controls this behavior.

In a programming or markup language buffer, when pressed/clicked at
the start or end of a delimited thing (including lists, comments,
strings, arrays/vectors, sets, functions and markup pair tags in a
markup language), and not at the end of a line:
ACTION KEY
Marks the thing for editing.
ASSIST KEY
Marks and kills the thing for yanking elsewhere.
Note that the press must be on the first character of the delimiter of the thing.
There are also drag actions that work on delimited things. Delimited things include parenthesized lists, single and double quoted strings, bracketed arrays/vectors, sets with braces, programming language functions and markup pair tags (e.g. <div> </div> in HTML).
If no region is selected when the Action Mouse Key is dragged from a thing delimiter to another location, it copies the delimited thing to the release point of the drag. The release location may be in the same or a different buffer but if in the same buffer it must be outside of the delimited thing itself. Similarly, the Assist Mouse Key kills (cuts) the delimited thing at its original location and yanks (pastes) it at the new location.
The start of the drag must be on the first character of the starting or ending delimiter. For strings and comments, the drag must start on the first line of the thing.
Experiment with these drag actions and you will quickly find them easy to use and indispensable.

called;
(5) dragged vertically from a modeline to within a window, the
modeline is moved to the point of the drag release, thereby
resizing its window and potentially its vertically neighboring
windows;
(6) dragged other than straight vertically from a modeline to another
window, duplicate the modeline’s window buffer to the window of
release;
(7) dragged from a bottommost modeline when the frame has a non-nil
drag-with-mode-line property, then move the frame until
release of the Action Mouse Key;
(8) otherwise, dragged from a another modeline to outside of
Emacs (MacOS only), create a new frame sized to match the
selected window with the same buffer.
ASSIST MOUSE KEY

modeline is moved to the point of the drag release, thereby
resizing its window and potentially its vertically neighboring
windows;
(6) dragged other than straight vertically from a modeline to another
window, swap buffers in the two windows;
(7) dragged from a bottommost modeline when the frame has a non-nil
drag-with-mode-line property, then move the frame until
release of the Action Mouse Key;
(8) dragged from a modeline to outside of Emacs (MacOS only),
create a new frame sized to match the selected window with
the same buffer. If there is only one window in the source
frame or if hycontrol-keep-window-flag is non-nil,
leave the original window and just clone it into the new
frame; otherwise, delete the original window.
If dragged from a window and released within a window modeline:
ACTION KEY
(1) If depress was on a buffer name in Buffer-menu/ibuffer mode or on
a file/directory in dired mode, splits the release window and displays
the item in the original release window.
(2) Otherwise, splits the release window and displays the depress window’s
buffer in the original release window.

referent in window of release.
See hmouse-drag-item-mode-forms for how to allow for draggable
items in other modes.
(2) Otherwise, creates a new link button at the drag start location,
linked to the drag end location. Action Key creates an implicit button;
Assist Key creates an explicit button.
In Hyperbole versions prior to 9, Assist Key drags between windows would
swap buffers. In version 9 and above, start or end the drag between
windows on a modeline to get this same behavior.

The flymake library comes with only a pulldown menu and no other
source buffer key bindings, forcing you to first display the list of
issues and then find the issue of interest and jump to it. Hyperbole
adds a source buffer keymap on the {C-c C-l} prefix that lets you
navigate and remediate flymake issues exclusively in the source
buffer. It also makes it more convenient to jump to the issue listing
buffer, to toggle flymake-mode on and off and to toggle whether
the movement between issue commands wrap around at the end of the
buffer or not.

By default, it just displays an error message. Set it to
hyperbole if you want it to display the Hyperbole
minibuffer menu or hyperbole-popup-menu to popup the
Hyperbole menubar menu.
ASSIST KEY
Runs the function stored in assist-key-default-function.
By default, it just displays an error message. Set it to
hkey-summarize if you want it to display a summary of
Smart Key behavior.

If you find any errors in Hyperbole’s operation or documentation, feel free to report them to <bug-hyperbole@gnu.org>. Be sure to use the {C-h h m r} Msg/Report-Hypb-Bug minibuffer menu item whenever you send a message to this address since that command will insert important system version information for you.
If you use Hyperbole mail or news support (see Buttons in Mail), a press of your Action Key on the Hyperbole mail list address will insert a description of your Hyperbole configuration information into your outgoing message, so that you do not have to type it. Otherwise, be sure to include the version numbers of your editor, Hyperbole and your window system. Your Hyperbole version number can be found in the top-level Hyperbole menu.
Below are some tips on how best to structure requests and discussion messages. If you share information about your use of Hyperbole with others, it will promote broader use and development of Hyperbole.
For example, write: “Subject: Typo in top-level Hyperbole minibuffer menu.” rather than: “Subject: Hyperbole bug”
If you have suggestions on how to improve Hyperbole, send them to <hyperbole-users@gnu.com> ({C-h h m c} minibuffer menu item Msg/Compose-Hypb-Mail). Here are some issues you might address:

This other-worldly reaction is of course an individual matter. Some people have canceled meditation trips to the Far East after discovering that pressing the Action Key in random contexts serves a similar purpose much more cheaply. We have not seen anyone’s mind turn to jelly but with the cognition Hyperbole saves you, you might just grow a second one. Eventually, you will be at peace and will understand that there is no adequate description of Hyperbole. Just let it flow through you.
Ok, joking aside, now that we have your attention, here are some serious questions and answers.
No, they offer very different capabilities when you compare them a bit more deeply. In fact, it makes sense to use them together and they are highly compatible. The only overlap we see is that Org-mode has a more limited kind of hyperlinks and offers some BBDB integration as Hyperbole does. For a list of some differences, see: https://www.emacswiki.org/emacs/Hyperbole.
Org-mode offers traditional Emacs outlining, todo list management, agenda and diary management, so it is very complementary to Hyperbole. It did not exist when Hyperbole was first developed.
Smart Key support for Org-mode is already in Hyperbole. Use the
hsys-org-enable-smart-keys customization variable to control
the Smart Keys and {M-RET} when in Org-mode with
hyperbole-mode active. t enables Smart Key support
everywhere. The symbol, buttons, is the default; it means the
Smart Keys are active only when point is within a Hyperbole button. A
nil value means no Smart Key support; Hyperbole gives Org
complete control over {M-RET} so that it behaves just as it
does normally in Org mode.
Since the Smart Mouse Keys are set up for use under many different
Emacs configurations, there is no easy way to provide user level
customization. Any mouse key binding changes require editing the
(hmouse-setup) and (hmouse-get-bindings) functions in the
hmouse-sh.el file.
To make the Smart Keys do new things in particular contexts, define new types of implicit buttons, see Implicit Buttons.
The hkey-alist and hmouse-alist variables in
hui-mouse.el and hui-window.el must be altered if you want
to change what the Smart Keys do in standard contexts. You should
then update the Smart Key summary documentation in the file,
man/hkey-help.txt, and then regenerate the readable forms of
this manual which includes that file.
Or what if someone sends a mail message with a button whose link referent I can’t access?
You receive an error that an action type is not defined or a link referent is not accessible/readable if you try to use the button. This is hardly different than trying to get through a locked door without a key; you try the doorknob, find that it is locked, and then realize that you need to take a different approach or else give up.
Like all communication, people need to coordinate, which usually requires an iterative process. If you get a mail message with a button for which you don’t have the action type, you mail the sender and request it.
Rather than typing the name for each, it is quicker to jump to the global button file and edit the buttons there as you would any explicit or implicit buttons. By default, the ButFile/PersonalFile menu item takes you to the file where global buttons are saved. Global buttons are saved near the end of this file.
When you think of a hyperspace that you depend on every day, you don’t want to have a single point of failure that can make you incapable of doing work. With Hyperbole, if some directories become unavailable for a particular time (e.g. the filesystems on which they reside are dismounted) you can still work elsewhere with minimal effect. We believe this to be a compelling factor to leave the design with distributed button attribute storage.
This design also permits the potential addition of buttons to read-only media.
Any category of button can make use of any action type. Some action types are useful as behavior definitions for a variety of button categories, so all action types are defined separately to give them independence from those types which apply them.
For implicit button types that require a lot of code, it is useful to add a module that includes the implicit button type definition, its action type definition and supporting code. Then simply load that module into your Emacs session.

This appendix is included for a number of reasons:
Without any serious interest from users, progress on these fronts will be slow. Here are some new features we have in mind, however.
There is as yet no means of transferring explicit buttons among buffers. We realize this is an important need. Users should be able to manipulate text with embedded buttons in ordinary ways. With this feature, Hyperbole would store the button attributes as text properties within the buffers so that if a button is copied, its attributes follow. When a buffer is saved, the attributes also will be saved.
This will complement the Koutliner editing mode by using simple one character keys that normally insert characters to instead modify the view of a Koutline and to move around in it, for ease of study. Switching between view and edit modes will also be simple.
Hyperbole is designed to let you rapidly navigate and manipulate large, distributed information spaces. Being able to directly manipulate entities in these spaces will accelerate understanding and production of new information. Already Hyperbole lets you drag buffers, windows, files, and directories and place them where you like. But there is much more that can be done to allow for higher-level browsing and information organization.
Trails are an extension to the basic history mechanism presently offered by Hyperbole. Trails will allow a user to capture, edit and store a specific sequence and set of views of information for later replay by other users. Conditional branching may also be supported.
The current design choice of storing buttons external to the source file was made under the assumption that people should be able to look at files that contain Hyperbole buttons with any standard editor or tool and not be bothered by the ugly button data (since they won’t be able to utilize the buttons anyway, they don’t need to see or have access to them).
In many contexts, embedding the button data within the source files may be a better choice, so a provision which would allow selection of either configuration may be added. Here are some of the PROs and CONs of both design choices:
POSITIVE NEGATIVE

need only search one file
per directory.
This will allow one to create buttons more flexibly. For example, button attributes could be given in any order. Entry of long code sequences, quick note taking and cross-referencing would also be made easier.
From the early stages of Hyperbole design, collaborative work environments have been considered. A simple facility has demonstrated broadcast of button activations to a number of workstations on a local area network, so that one user can lead others around an information space, as during an online design review. (This facility was never adapted to the current Hyperbole release, however). Nowadays you could just use a screen sharing program.
