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. The stand-alone Info reader program has its own set of variables, described in Manipulating Variables.
nil(try default directory). If not initialized Info uses the environment variable INFOPATH to initialize it, or
Info-default-directory-listif 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-modeis called. By default, it contains the hook
turn-on-font-lockwhich enables highlighting of Info files. You can change how the highlighting looks by customizing the faces
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.
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 visible.
nil. Setting it to a value that is neither
tproduces an intermediate behavior, hiding a limited amount of text, but showing all text that could potentially be useful.
nilvalue, <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
nilresults 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.
nilvalue, 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!")
