;;; Commentary:
;; Note that nowadays we expect Info files to be made using makeinfo.
;; In particular we make these assumptions:
;; - a menu item MAY contain colons but not colon-space ": "
;; - a menu item ending with ": " (but not ":: ") is an index entry
;; - a node name MAY NOT contain a colon
;; This distinction is to support indexing of computer programming
;; language terms that may contain ":" but not ": ".

"Info mode provides commands for browsing through the Info documentation tree.
1991-07-13 07:49:50 +00:00
Documentation in Info is divided into \"nodes\", each of which discusses
one topic and contains references to other nodes which discuss related
topics. Info has commands to follow the references and show you other nodes.
\\<Info-mode-map>\
1991-07-13 07:49:50 +00:00
\\[Info-help] Invoke the Info tutorial.
1998-04-28 18:13:00 +00:00
\\[Info-exit] Quit Info: reselect previously selected buffer.
1991-07-13 07:49:50 +00:00
Selecting other nodes:
1994-08-18 01:08:03 +00:00
\\[Info-mouse-follow-nearest-node]
Follow a node reference you click on.
This works with menu items, cross references, and
the \"next\", \"previous\" and \"up\", depending on where you click.
1998-04-28 18:13:00 +00:00
\\[Info-follow-nearest-node] Follow a node reference near point, like \\[Info-mouse-follow-nearest-node].
1991-07-13 07:49:50 +00:00
\\[Info-next] Move to the \"next\" node of this node.
\\[Info-prev] Move to the \"previous\" node of this node.
1991-07-13 07:49:50 +00:00
\\[Info-up] Move \"up\" from this node.
\\[Info-menu] Pick menu item specified by name (or abbreviation).
2001-12-29 18:02:49 +00:00
Picking a menu item causes another node to be selected.
1992-02-07 21:40:34 +00:00
\\[Info-directory] Go to the Info directory node.
\\[Info-top-node] Go to the Top node of this file.
\\[Info-final-node] Go to the final node in this file.
\\[Info-backward-node] Go backward one node, considering all nodes as forming one sequence.
\\[Info-forward-node] Go forward one node, considering all nodes as forming one sequence.
\\[Info-next-reference] Move cursor to next cross-reference or menu item.
\\[Info-prev-reference] Move cursor to previous cross-reference or menu item.
1991-07-13 07:49:50 +00:00
\\[Info-follow-reference] Follow a cross reference. Reads name of reference.
\\[Info-history-back] Move back in history to the last node you were at.
\\[Info-history-forward] Move forward in history to the node you returned from after using \\[Info-history-back].
\\[Info-history] Go to menu of visited nodes.
\\[Info-toc] Go to table of contents of the current Info file.
1991-07-13 07:49:50 +00:00
Moving within a node:
1997-12-22 22:28:11 +00:00
\\[Info-scroll-up] Normally, scroll forward a full screen.
2001-12-29 18:02:49 +00:00
Once you scroll far enough in a node that its menu appears on the
screen but after point, the next scroll moves into its first
subnode. When after all menu items (or if there is no menu),
move up to the parent node.
1997-12-22 22:28:11 +00:00
\\[Info-scroll-down] Normally, scroll backward. If the beginning of the buffer is
2001-12-29 18:02:49 +00:00
already visible, try to go to the previous menu entry, or up
if there is none.
\\[beginning-of-buffer] Go to beginning of node.
1991-07-13 07:49:50 +00:00
Advanced commands:
\\[Info-search] Search through this Info file for specified regexp,
2001-12-29 18:02:49 +00:00
and select the node in which the next occurrence is found.
\\[Info-search-case-sensitively] Search through this Info file for specified regexp case-sensitively.

(Info-search-case-sensitively, Info-search-next): New fun. (Info-up): Move point to the menu item of the current node. (Info-history): New fun. Add *info-history* to same-window-buffer-names. (Info-toc): New fun. Add *info-toc* to same-window-buffer-names. (Info-insert-toc): New fun. (Info-build-toc): New fun. (Info-follow-reference): Add new arg `fork'. Doc fix. Replace [ \n\t]* by [ \n\t]+ in the *Note regexp. For references with the same name prefer the reference closest to point. (Info-next-reference): Replace * by + in the *Note regexp. Add regexp for http:// and ftp://. Skip the *Note prefix. (Info-prev-reference): Replace * by + in the *Note regexp. Add regexp for http:// and ftp://. Skip the *Note prefix. (Info-follow-nearest-node): Add new arg `fork'. (Info-try-follow-nearest-node): Add new arg `fork'. Call browse-url for http:// and ftp:// references. Set Info-reference-name for index entries.

(Info-fontify-node): Add docstring. Add local vars fontify-visited-p and not-fontified-p. If not-fontified-p is t then fontify header line, titles, menu headers, http and ftp references, refill paragraphs. If not-fontified-p is t or fontify-visited-p is t then fontify cross references, menu items. Fontify menu headers. Fontify http and ftp references. Change regexp for cross references to require whitespace after *Note, add matching groups for file and node names. Remove hack for quote. Use display property for Info-hide-note-references=t. Use fifth or fourth match for help-echo. Display visited nodes in a different face. Unhide file names of external references. Unhide newlines. Display visited menu items in a different face.
