The following variables may modify the behavior of Info-mode in Emacs; you may wish to set one or several of these variables interactively, or in your init file. See Examining and Setting Variables in The GNU Emacs Manual. The stand-alone Info reader program has its own set of variables, described in Manipulating Variables in GNU Info.
Info-directory-list ¶The list of directories to search for Info files. Each element is a
string (directory name) or nil (try default directory). If not
initialized Info uses the environment variable INFOPATH to
initialize it, or Info-default-directory-list in addition to
the value returned by the Info--default-directory-list function
if there is no INFOPATH variable in the environment.
If you wish to customize the Info directory search list for both Emacs
Info and stand-alone Info, it is best to set the INFOPATH
environment variable, since that applies to both programs.
Info-additional-directory-list ¶A list of additional directories to search for Info documentation files. These directories are not searched for merging the dir file.
Info-mode-hook ¶Hooks run when Info-mode is called. By default, it contains
the hook turn-on-font-lock which enables highlighting of Info
files. You can change how the highlighting looks by customizing the
faces info-node, info-xref, info-xref-visited,
info-header-xref, info-header-node, info-menu-header,
info-menu-star, and info-title-n (where n
is the level of the section, a number between 1 and 4). To customize
a face, type M-x customize-face RET face RET,
where face is one of the face names listed here.
Maximum size of menu to fontify if font-lock-mode is non-nil.
Info-fontify-visited-nodes ¶If non-nil, menu items and cross-references pointing to visited
nodes are displayed in the info-xref-visited face.
Info-use-header-line ¶If non-nil, Emacs puts in the Info buffer a header line showing
the ‘Next’, ‘Prev’, and ‘Up’ links. A header line does
not scroll with the rest of the buffer, making these links always
visible.
Info-hide-note-references ¶As explained in earlier sections, the Emacs version of Info normally
hides some text in menus and cross references. It also replaces the
‘*note’ prefix of each cross reference with a more grammatically
correct ‘see’. This is the effect of the default value of this
option, t. Setting this option to nil disables both
hiding and replacing of the original cross reference text, and Emacs
will then display them as they are in the Info file. If you set it to
the value hide, Emacs will do the same as with t, but
will also remove ‘*note’ without replacing it with anything.
Setting it to any other non-nil value produces an intermediate
behavior, hiding a limited amount of text, but showing all text that
could potentially be useful, including the name of the node that is
the target of the cross reference and its file if it is different from
the current file.
Info-scroll-prefer-subnodes ¶If set to a non-nil value, SPC and BACKSPACE (or
DEL, or S-SPC) keys in a menu visit subnodes of the
current node before scrolling to its end or beginning, respectively.
For example, if the node’s menu appears on the screen, the next
SPC moves to a subnode indicated by the following menu item.
Setting this option to nil results in behavior similar to the
stand-alone Info reader program, which visits the first subnode from
the menu only when you hit the end of the current node. The default
is nil.
Info-isearch-search ¶If non-nil, isearch in Info searches through multiple nodes.
Info-enable-active-nodes ¶When set to a non-nil value, allows Info to execute Lisp code
associated with nodes. The Lisp code is executed when the node is
selected. The Lisp code to be executed should follow the node
delimiter (the ‘DEL’ character) and an ‘execute: ’ tag, like
this:
^_execute: (message "This is an active node!")
