Info allows you to override the default key-to-command bindings and variable settings described in this document. (The --vi-keys option rebinds many keys at once; see --vi-keys.)
On startup, GNU Info looks for a configuration file in the invoker’s
HOME directory called .infokey, i.e.,
~/.infokey.3 If it is present, then Info adopts the key bindings
and variable settings contained therein. To use an alternative
configuration file, use the --init-file option
(see --init-file).
Variables may also be set on the command line with the --variable option (see variable-assignment). Variable settings on the command line override settings from the .infokey file.
Due to the limitations of DOS filesystems,
the MS-DOS version of Info looks for a file _infokey instead. If
the HOME variable is not defined, Info additionally looks in the
current directory.
