Macros which can be used for the display of cross references.
This is used when reftex-view-crossref is called with point in an
argument of a macro. Note that crossref viewing for citations,
references (both ways) and index entries is hard-coded. This variable
is only to configure additional structures for which crossreference
viewing can be useful. Each entry has the structure
(macro-re search-re highlight).
macro-re is matched against the macro. search-re is the regexp used to search for cross references. ‘%s’ in this regexp is replaced with the macro argument at point. highlight is an integer indicating which subgroup of the match should be highlighted.
Non-nil means, initially turn automatic viewing of crossref info
on. Automatic viewing of crossref info normally uses the echo area.
Whenever point is idle for more than reftex-idle-time seconds on
the argument of a \ref or \cite macro, and no other
message is being displayed, the echo area will display information about
that cross reference. You can also set the variable to the symbol
window. In this case a small temporary window is used for the
display. This feature can be turned on and off from the menu
(Ref->Options).
Time (secs) Emacs has to be idle before automatic crossref display or toc recentering is done.
Citation format used to display citation info in the message area. See
the variable reftex-cite-format for possible percent
escapes.
Non-nil means, automatic citation display will revisit files if
necessary. When nil, citation display in echo area will only be active
for cached echo strings (see reftex-cache-cite-echo), or for
BibTeX database files which are already visited by a live associated
buffers.
Non-nil means, the information displayed in the echo area for
cite macros (see variable reftex-auto-view-crossref) is cached and
saved along with the parsing information. The cache survives document
scans. In order to clear it, use M-x reftex-reset-mode.
