** Init file changes
-You can now put the init files .emacs and .emacs_SHELL under
-~/.emacs.d or directly under ~. Emacs will find them in either place.

** The info-search bindings on C-h C-f, C-h C-k and C-h C-i
of specifying the current directory. Normally that means to visit the
directory with Dired.
+You can get the old behavior by typing C-x C-f M-n RET, which fetches
+the actual file name into the minibuffer.
+
+++
** The completion commands TAB, SPC and ? in the minibuffer apply only
to the text before point. If there is text in the buffer after point,
it remains unchanged.
+** When Emacs prompts for file names, SPC no longer completes the file name.
+This is so filenames with embedded spaces could be input without the
+need to quote the space with a C-q. The underlying changes in the
+keymaps that are active in the minibuffer are described below under
+"New keymaps for typing file names".

** M-o now is the prefix key for setting text properties;
M-o M-o requests refontification.
* Editing Changes in Emacs 22.1
+++
-** The max size of buffers and integers has been doubled.
-On 32bit machines, it is now 256M (i.e. 268435455).
-
-+++
-** M-g is now a prefix key.
-M-g g and M-g M-g run goto-line.
-M-g n and M-g M-n run next-error (like C-x `).
-M-g p and M-g M-p run previous-error.
-
-+++
-** C-u M-g M-g switches to the most recent previous buffer,
-and goes to the specified line in that buffer.
-
-When goto-line starts to execute, if there's a number in the buffer at
-point then it acts as the default argument for the minibuffer.
-
-+++
-** The old bindings C-M-delete and C-M-backspace have been deleted,
-since there are situations where one or the other will shut down
-the operating system or your X server.
+** !MEM FULL! at the start of the mode line indicates that Emacs
+cannot get any more memory for Lisp data. This often means it could
+crash soon if you do things that use more memory. On most systems,
+killing buffers will get out of this state. If killing buffers does
+not make !MEM FULL! disappear, you should save your work and start
+a new Emacs.
+++
-** line-move-ignore-invisible now defaults to t.
-
-+++
-** When the undo information of the current command gets really large
-(beyond the value of `undo-outer-limit'), Emacs discards it and warns
-you about it.
-
-+++
-** `apply-macro-to-region-lines' now operates on all lines that begin
-in the region, rather than on all complete lines in the region.
+** The max size of buffers and integers has been doubled.
+On 32bit machines, it is now 256M (i.e. 268435455).

C-h c, C-h k, C-h w, and C-h f now handle remapped interactive commands.
-
- C-h c and C-h k report the actual command (after possible remapping)
run by the key sequence.
-
- C-h w and C-h f on a command which has been remapped now report the
command it is remapped to, and the keys which can be used to run
that command.
For example, if C-k is bound to kill-line, and kill-line is remapped
to new-kill-line, these commands now report:
-
- C-h c and C-h k C-k reports:
C-k runs the command new-kill-line
-
- C-h w and C-h f kill-line reports:
kill-line is remapped to new-kill-line which is on C-k, <deleteline>

- C-h w and C-h f new-kill-line reports:
new-kill-line is on C-k

*** The new command `describe-char' (C-u C-x =) pops up a buffer with
controls whether or not the function `make-auto-save-file-name' will
attempt to construct a unique auto-save name (e.g. for remote files).
++++
+*** The new option `write-region-inhibit-fsync' disables calls to fsync
+in `write-region'. This can be useful on laptops to avoid spinning up
+the hard drive upon each file save. Enabling this variable may result
+in data loss, use with care.

+++
*** If the user visits a file larger than `large-file-warning-threshold',
Emacs asks for confirmation.
** Minibuffer changes:
++++
+*** The new file-name-shadow-mode is turned ON by default, so that when
+entering a file name, any prefix which Emacs will ignore is dimmed.
+
+++
*** There's a new face `minibuffer-prompt'.
Emacs adds this face to the list of text properties stored in the
parts less visible than normal, so that the rest of the differing
parts is, by contrast, slightly highlighted.
+Above fontification is always done when listing completions is
+triggered at minibuffer. If you want to fontify completions whose
+listing is triggered at the other normal buffer, you have to pass

-to another, even within a frame. If you set the variable
-mouse-autoselect-window to non-nil value, moving the mouse to a
-different Emacs window will select that window (minibuffer window can

* New Modes and Packages in Emacs 22.1
+** Rcirc is now part of the Emacs distribution.
+
+Rcirc is an Internet relay chat (IRC) client. It supports
+simultaneous connections to multiple IRC servers. Each discussion
+takes place in its own buffer. For each connection you can join
+several channels (many-to-many) and participate in private
+(one-to-one) chats. Both channel and private chats are contained in
+separate buffers.

+Newsticker asynchronously retrieves headlines (RSS) from a list of news
+sites, prepares these headlines for reading, and allows for loading the
+corresponding articles in a web browser. Its documentation is in a
+separate manual.

kmacro-call-repeat-with-arg.
Keyboard macros can now be debugged and edited interactively.

** The TCL package tcl-mode.el was replaced by tcl.el.
This was actually done in Emacs-21.1, and was not documented.
+
+** The new package scroll-lock.el provides the Scroll Lock minor mode
+for pager-like scrolling. Keys which normally move point by line or
+paragraph will scroll the buffer by the respective amount of lines
+instead and point will be kept vertically fixed relative to window
+boundaries during scrolling.

* Changes in Specialized Modes and Packages in Emacs 22.1:
+** Changes in Allout
+
+*** Topic cryptography added, enabling easy gpg topic encryption and
+decryption. Per-topic basis enables interspersing encrypted-text and
+clear-text within a single file to your hearts content, using symmetric
+and/or public key modes. Time-limited key caching, user-provided
+symmetric key hinting and consistency verification, auto-encryption of
+pending topics on save, and more, make it easy to use encryption in
+powerful ways.
+
+*** many substantial fixes and refinements, including:
+
+ - repaired inhibition of inadvertent edits to concealed text
+ - repaired retention of topic body hanging indent upon topic depth shifts
+ - prevent "containment discontinuities" where a topic is shifted deeper
+ than the offspring-depth of its container
+ - easy to adopt the distinctive bullet of a topic in a topic created
+ relative to it, or select a new one, or use the common topic bullet
+ - plain bullets, by default, now alternate between only two characters
+ ('.' and ','), yielding less cluttered outlines
+ - many internal fixes
+ - version number incremented to 2.1
+
+** The variable `woman-topic-at-point' was renamed
+to `woman-use-topic-at-point' and behaves differently: if this
+variable is non-nil, the `woman' command uses the word at point
+automatically, without asking for a confirmation. Otherwise, the word
+at point is suggested as default, but not inserted at the prompt.

** Changes to cmuscheme
*** A numeric prefix argument of `info' selects an Info buffer
with the number appended to the `*info*' buffer name (e.g. "*info*<2>").
----
++++
*** isearch in Info uses Info-search and searches through multiple nodes.
Before leaving the initial Info node isearch fails once with the error
or the default isearch search function that wraps around the current
Info node.
+---
*** New search commands: `Info-search-case-sensitively' (bound to S),
`Info-search-backward', and `Info-search-next' which repeats the last
search without prompting for a new search string.
++++
*** New command `Info-history-forward' (bound to r and new toolbar icon)
moves forward in history to the node you returned from after using
`Info-history-back' (renamed from `Info-last').
+---
*** New command `Info-history' (bound to L) displays a menu of visited nodes.
+---
*** New command `Info-toc' (bound to T) creates a node with table of contents
from the tree structure of menus of the current Info file.
++++
*** New command `info-apropos' searches the indices of the known
Info files on your system for a string, and builds a menu of the
possible matches.
+---
*** New command `Info-copy-current-node-name' (bound to w) copies
the current Info node name into the kill ring. With a zero prefix
arg, puts the node name inside the `info' function call.
----
++++
*** New face `info-xref-visited' distinguishes visited nodes from unvisited
and a new option `Info-fontify-visited-nodes' to control this.
+---
*** http and ftp links in Info are now operational: they look like cross
references and following them calls `browse-url'.

+The ten most recent files can be quickly opened by using the shortcut
+keys 1 to 9, and 0, when the recent list is displayed in a buffer via
+the `recentf-open-files', or `recentf-open-more-files' commands.

The `recentf-keep' option replaces `recentf-keep-non-readable-files-p'
and provides a more general mechanism to customize which file names to
keep in the recent list.
-With the more advanced option: `recentf-filename-handler', you can

++++
+** Speedbar changes:
+
+*** Speedbar items can now be selected by clicking mouse-1, based on
+the `mouse-1-click-follows-link' mechanism.
+
+*** SPC and DEL are no longer bound to scroll up/down in the speedbar
+keymap.
+
+*** The new command `speedbar-toggle-line-expansion', bound to SPC,
+contracts or expands the line under the cursor.
+
+*** New command `speedbar-create-directory', bound to `M'.
+
+*** The new commands `speedbar-expand-line-descendants' and
+`speedbar-contract-line-descendants', bound to `[' and `]'
+respectively, expand and contract the line under cursor with all of
+its descendents.
+
+*** The new user option `speedbar-query-confirmation-method' controls
+how querying is performed for file operations. A value of 'always
+means to always query before file operations; 'none-but-delete means
+to not query before any file operations, except before a file
+deletion.
+
+*** The new user option `speedbar-select-frame-method' specifies how
+to select a frame for displaying a file opened with the speedbar. A
+value of 'attached means to use the attached frame (the frame that
+speedbar was started from.) A number such as 1 or -1 means to pass
+that number to `other-frame'.
+
+*** The new user option `speedbar-use-tool-tips-flag', if non-nil,
+means to display tool-tips for speedbar items.
+
+*** The frame management code in speedbar.el has been split into a new
+`dframe' library. Emacs Lisp code that makes use of the speedbar
+should use `dframe-attached-frame' instead of
+`speedbar-attached-frame', `dframe-timer' instead of `speedbar-timer',
+`dframe-close-frame' instead of `speedbar-close-frame', and
+`dframe-activity-change-focus-flag' instead of
+`speedbar-activity-change-focus-flag'. The variables

-** New variable `hs-set-up-overlay' allows customization of the overlay
+** Hideshow mode changes
+
+*** New variable `hs-set-up-overlay' allows customization of the overlay
used to effect hiding for hideshow minor mode. Integration with isearch
handles the overlay property `display' specially, preserving it during
temporary overlay showing in the course of an isearch operation.
+*** New variable `hs-allow-nesting' non-nil means that hiding a block does
+not discard the hidden state of any "internal" blocks; when the parent
+block is later shown, the internal blocks remain hidden. Default is nil.
+
+++
** `hide-ifdef-mode' now uses overlays rather than selective-display
to hide its text. This should be mostly transparent but slightly
** The variable `mac-keyboard-text-encoding' and the constants
`kTextEncodingMacRoman', `kTextEncodingISOLatin1', and
`kTextEncodingISOLatin2' are obsolete.

+*** New macro `eval-at-startup' specifies expressions to
+evaluate when Emacs starts up. If this is done after startup,
+it evaluates those expressions immediately.
+
+This is useful in packages that can be preloaded.
+
*** `list-faces-display' takes an optional argument, REGEXP.
If it is non-nil, the function lists only faces matching this regexp.
for compatibility, an internal variable which exists only for this
purpose.
++++
+*** The function `read-buffer' follows the convention for reading from
+the minibuffer with a default value: if DEF is non-nil, the minibuffer
+prompt provided in PROMPT is edited to show the default value provided
+in DEF before the terminal colon and space.
+
** Local variables lists:
+++
This is useful for autoloaded handlers, to prevent them from being
autoloaded when not really necessary.
++++
+*** The function `make-auto-save-file-name' is now handled by file
+name handlers. This will be exploited for remote files mainly.
+
** Input changes:

+++
** Enhancements to keymaps.
+*** New keymaps for typing file names
+
+Two new keymaps, `minibuffer-local-filename-completion-map' and
+`minibuffer-local-must-match-filename-map', apply whenever
+Emacs reads a file name in the minibuffer. These key maps override
+the usual binding of SPC to `minibuffer-complete-word' (so that file
+names with embedded spaces could be typed without the need to quote
+the spaces).
+
*** Cleaner way to enter key sequences.
You can enter a constant key sequence in a more natural format, the
If non-nil, that says to preserve the window's current margin, fringe,
and scroll-bar settings.
++++
+*** The new function `window-tree' returns a frame's window tree.
+
++++
+*** The functions `get-lru-window' and `get-largest-window' take an optional
+argument `dedicated'. If non-nil, those functions do not ignore
+dedicated windows.
+
++++
+*** The new function `adjust-window-trailing-edge' moves the right
+or bottom edge of a window. It does not move other window edges.
+
+++
** Customizable fringe bitmaps
an event is composed by combining the ID of the hot-spot with the
mouse event, e.g. [area4 mouse-1] if the hot-spot's ID is `area4'.
++++
+*** The function `find-image' now searches in etc/images/ and etc/.
+The new variable `image-load-path' is a list of locations in which to
+search for image files. The default is to search in etc/images, then
+in etc/, and finally in the directories specified by `load-path'.
+Subdirectories of etc/ and etc/images are not recursively searched; if
+you put an image file in a subdirectory, you have to specify it
+explicitly; for example, if an image is put in etc/images/foo/bar.xpm:
+
+ (defimage foo-image '((:type xpm :file "foo/bar.xpm")))

so that :inherit face lists operate identically to face lists in text
`face' properties.

+*** On terminals, faces with the :inverse-video attribute are displayed
+with swapped foreground and background colors even when one of them is
+not specified. In previous releases of Emacs, if either foreground
+or background color was unspecified, colors were not swapped. This
+was inconsistent with the face behavior under X.

*** `set-fontset-font', `fontset-info', `fontset-font' now operate on
the default fontset if the argument NAME is nil..
*** Custom support
The variables font-lock-face-attributes, font-lock-display-type and
