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.
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
initialize it, or
Info-default-directory-list 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
environment variable, since that applies to both programs.
A list of additional directories to search for Info documentation files. These directories are not searched for merging the dir file.
Hooks run when
Info-mode is called. By default, it contains
turn-on-font-lock which enables highlighting of Info
files. You can change how the highlighting looks by customizing the
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, menu items and cross-references pointing to visited
nodes are displayed in the
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
As explained in earlier nodes, the Emacs version of Info normally
hides some text in menus and cross-references. You can completely
disable this feature, by setting this option to
it to a value that is neither
t produces an
intermediate behavior, hiding a limited amount of text, but showing
all text that could potentially be useful.
If set to a non-
nil value, SPC and BACKSPACE (or
DEL) 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, isearch in Info searches through multiple 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
^_execute: (message "This is an active node!")
