* Changes in Emacs 22.1
++++
** The commands copy-file, rename-file, make-symbolic-link and
add-name-to-file, when given a directory as the "new name" argument,
convert it to a file name by merging in the within-directory part of
commands cp, mv, and ln follow.) Thus, M-x copy-file RET ~/foo RET
/tmp RET copies ~/foo to /tmp/foo.
++++
** M-o now is the prefix key for setting text properties;
M-o M-o requests refontification.
++++
** M-g is now a prefix key. M-g g and M-g M-g run goto-line.
++++
** font-lock-lines-before specifies a number of lines before the
current line that should be refontified when you change the buffer.
The default value is 1.
++++
** C-u M-x goto-line now 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.
-** Emacs now responds to mouse-clicks on the mode-line, header-line
-and display margin, when run in an xterm.

+** Emacs now responds to mouse-clicks on the mode-line, header-line and
+display margin, when run in an xterm.

** M-SPC (just-one-space) when given a numeric argument N
converts whitespace around point to N spaces.
++++
** Control characters and escape glyphs are now shown in the new
escape-glyph face.
you don't want the .type-break file in your home directory or are
annoyed by the need for interaction when you kill Emacs.
+---
** display-battery has been replaced by display-battery-mode.
+---
** calculator.el now has radix grouping mode, which is available when
`calculator-output-radix' is non-nil. In this mode a separator
character is used every few digits, making it easier to see byte
(beyond the value of `undo-outer-limit'), Emacs discards it and warns
you about it.
++++
** line-move-ignore-invisible now defaults to t.
** In Outline mode, hide-body no longer hides lines at the top
will start up Emacs on an initial frame of 100x20 with red background,
irrespective of geometry or background setting on the Windows registry.
+---
** The terminal emulation code in term.el has been improved, it can
run most curses applications now.
*** The function `eval-defun' (C-M-x) called on defface reinitializes
the face to the value specified in the defface expression.
++++
*** Typing C-x C-e twice prints the value of the integer result
in additional formats (octal, hexadecimal, character) specified
by the new function `eval-expression-print-format'. The same
function also defines the result format for `eval-expression' (M-:),
`eval-print-last-sexp' (C-j) and some edebug evaluation functions.
+---
** New input method chinese-sisheng for inputting Chinese Pinyin
characters.
++++
** New command quail-show-key shows what key (or key sequence) to type
in the current input method to input a character at point.
++++
** Convenient commands to switch buffers in a cyclic order are C-x <left>
(prev-buffer) and C-x <right> (next-buffer).
+---
** Commands winner-redo and winner-undo, from winner.el, are now bound to
C-c <left> and C-c <right>, respectively. This is an incompatible change.
** New command line option -nbc or --no-blinking-cursor disables
the blinking cursor on graphical terminals.
++++
** C-h v and C-h f commands now include a hyperlink to the C source for
variables and functions defined in C (if the C source is available).
+---
** When used interactively, `format-write-file' now asks for confirmation
before overwriting an existing file, unless a prefix argument is
supplied. This behavior is analogous to `write-file'.
++++
** You can now use Auto Revert mode to `tail' a file.
If point is at the end of a file buffer before reverting, Auto Revert
mode keeps it at the end after reverting. Similarly if point is
mode Auto Revert Tail mode. The function `auto-revert-tail-mode'
toggles this mode.
++++
** Auto Revert mode is now more careful to avoid excessive reverts and
other potential problems when deciding which non-file buffers to
revert. This matters especially if Global Auto Revert mode is enabled
which it is active. If the option is nil, the default, then this info
only gets updated whenever the buffer gets reverted.
++++
** New command `Buffer-menu-toggle-files-only' toggles display of file
buffers only in the Buffer Menu. It is bound to `T' in Buffer Menu
mode.
+---
** M-x compile has become more robust and reliable
Quite a few more kinds of messages are recognized. Messages that are
** Grep has been decoupled from compilation mode setup.
+---
*** There's a new separate package grep.el.
+---
*** M-x grep has been adapted to new compile
Hits are fontified in green, and hits in binary files in orange. Grep buffers
can be saved and automatically revisited with the new Grep mode.
+---
*** Grep commands now have their own submenu and customization group.
+++
*** `grep-find' is now also available under the name `find-grep' where
people knowing `find-grep-dired' would probably expect it.
+---
*** The new variables `grep-window-height', `grep-auto-highlight', and
`grep-scroll-output' can be used to override the corresponding
compilation mode settings for grep commands.
++++
*** New option `grep-highlight-matches' highlightes matches in *grep*
buffer. It uses a special feature of some grep programs which accept
--color option to output markers around matches. When going to the next
buffer. Otherwise, if `grep-highlight-matches' is nil, the whole
source line is highlighted.
++++
*** New key bindings in grep output window:
SPC and DEL scrolls window up and down. C-n and C-p moves to next and
previous match in the grep window. RET jumps to the source line of
previous or next file in the grep output. TAB also jumps to the next
file.
++++
** New options `next-error-highlight' and `next-error-highlight-no-select'
specify the method of highlighting of the corresponding source line
in new face `next-error'.
++++
** A new minor mode `next-error-follow-minor-mode' can be used in
compilation-mode, grep-mode, occur-mode, and diff-mode (i.e. all the
modes that can use `next-error'). In this mode, cursor motion in the
matches, compilation errors, etc. This minor mode can be toggled with
C-c C-f.
++++
** M-x diff uses diff-mode instead of compilation-mode.
++++
** M-x compare-windows now can automatically skip non-matching text to
resync points in both windows.
+++
** Desktop package
++++
*** Desktop saving is now a minor mode, desktop-save-mode. Variable
desktop-enable is obsolete. Customize desktop-save-mode to enable desktop
saving.
+---
*** Buffers are saved in the desktop file in the same order as that in the
buffer list.
++++
*** The desktop package can be customized to restore only some buffers immediately,
remaining buffers are restored lazily (when Emacs is idle).
- desktop-lazy-verbose. Verbose reporting of lazily created buffers.
- desktop-lazy-idle-delay. Idle delay before starting to create buffers.
++++
*** New command line option --no-desktop
*** New hooks:
enclosed in single quotes and preceded by `info anchor' or `Info
anchor' (in addition to earlier `info node' and `Info node').
++++
** The max size of buffers and integers has been doubled.
On 32bit machines, it is now 256M (i.e. 268435455).
** Enhancements to apropos commands:
++++
*** The apropos commands now accept a list of words to match.
When more than one word is specified, at least two of those words must
be present for an item to match. Regular expression matching is still
When enabled, it makes all invisible text visible. When disabled, it
restores the previous value of `buffer-invisibility-spec'.
+---
** New command `kill-whole-line' kills an entire line at once.
By default, it is bound to C-S-<backspace>.
** New commands to operate on pairs of open and close characters:
`insert-pair', `delete-pair', `raise-sexp'.
++++
** A prefix argument of C-M-q in Emacs Lisp mode pretty-printifies the
list starting after point.
** Dired mode:
+---
*** New faces dired-header, dired-mark, dired-marked, dired-flagged,
dired-ignored, dired-directory, dired-symlink, dired-warning
introduced for Dired mode instead of font-lock faces.
doublequotes make no difference in the shell, but they prevent
special treatment in `dired-do-shell-command'.
++++
*** In Dired, the w command now copies the current line's file name
into the kill ring. With a zero prefix arg, copies absolute file names.
** Info mode:
++++
*** 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
message [initial node], and with subsequent C-s/C-r continues through
---
*** Info-index offers completion.
+---
** Support for the SQLite interpreter has been added to sql.el by calling
'sql-sqlite'.
*** The new command bibtex-copy-summary-as-kill pushes summary
of BibTeX entry to kill ring (bound to C-c C-t).
++++
** When display margins are present in a window, the fringes are now
displayed between the margins and the buffer's text area, rather than
at the edges of the window.
++++
** A window may now have individual fringe and scroll-bar settings,
in addition to the individual display margin settings.
These functions return the current locations of the vertical and
horizontal scroll bars in a frame or window.
----
++++
** Emacs now supports drag and drop for X. Dropping a file on a window
opens it, dropping text inserts the text. Dropping a file on a dired
buffer copies or moves the file to that directory.
++++
** Under X, mouse-wheel-mode is turned on by default.
** The X resource useXIM can be used to turn off use of XIM, which may
If the configure option `--without-xim' was used to turn off use of
XIM by default, the X resource useXIM can be used to turn it on.
++++
** `undo-only' does an undo which does not redo any previous undo.
** `uniquify-strip-common-suffix' tells uniquify to prefer
`file|dir1' and `file|dir2' to `file|dir1/subdir' and `file|dir2/subdir'.
++++
** If the user visits a file larger than `large-file-warning-threshold',
Emacs prompts her for confirmation.
+---
** A UTF-7 coding system is available in the library `utf-7'.
+---
** GUD mode has its own tool bar for controlling execution of the inferior
and other common debugger commands.
`recentf-menu-append-commands-p'. The old names remain available as
aliases, but have been marked obsolete.
++++
** The default for the paper size (variable ps-paper-type) is taken
from the locale.
++++
** 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.
+---
** partial-completion-mode now does partial completion on directory names.
** skeleton.el now supports using - to mark the skeleton-point without
`--display' which tell Emacs respectively to evaluate the given elisp
expression and to use the given display when visiting files.
++++
** User option `server-mode' can be used to start a server process.
+++
When the file is maintained under version control, that information
appears between the position information and the major mode.
++++
** C-x s (save-some-buffers) now offers an option `d' to diff a buffer
against its file, so you can see what changes you would be saving.

** The new command `revert-buffer-with-coding-system' (C-x RET r)
revisits the current file using a coding system that you specify.
specified for that character, the commands by default customize those
faces.

** New language environments: French, Ukrainian, Tajik,
Bulgarian, Belarusian, Ukrainian, UTF-8, Windows-1255, Welsh, Latin-6,
Latin-7, Lithuanian, Latvian, Swedish, Slovenian, Croatian, Georgian,
Italian, Russian, Malayalam, Tamil, Russian, Chinese-EUC-TW. (Set up
automatically according to the locale.)
+---
** Indian support has been updated.
The in-is13194 coding system is now Unicode-based. CDAC fonts are
assumed. There is a framework for supporting various

latter is used by GNU locales.
+---
** The utf-8/16 coding systems have been enhanced.
By default, untranslatable utf-8 sequences are simply composed into
single quasi-characters. User option `utf-translate-cjk-mode' (it is
one-dimensional internal charsets, specifically the ISO-8859 ones.
The utf-16 coding system is affected similarly.

+---
** iso-10646-1 (`Unicode') fonts can be used to display any range of
characters encodable by the utf-8 coding system. Just specify the
fontset appropriately.

** New command `ucs-insert' inserts a character specified by its
unicode.
mule-unicode-0100-24ff charsets) on decoding. Note that this mode
will often effectively clobber data with an iso-2022 encoding.
+---
** There is support for decoding Greek and Cyrillic characters into
either Unicode (the mule-unicode charsets) or the iso-8859 charsets,
when possible. The latter are more space-efficient. This is
`auto-hscroll-mode'. The old name is still available as an alias.
** TeX modes:
+
*** C-c C-c prompts for a command to run, and tries to offer a good default.
+
+++
*** The user option `tex-start-options-string' has been replaced
by two new user options: `tex-start-options', which should hold
command-line options to feed to TeX, and `tex-start-commands' which should hold
TeX commands to use at startup.
+
*** verbatim environments are now highlighted in courier by font-lock
and super/sub-scripts are made into super/sub-scripts.
`query-replace' and related functions simply ignore
a match if part of it has a read-only property.
++++
** When used interactively, the commands `query-replace-regexp' and
`replace-regexp' allow \,expr to be used in a replacement string,
where expr is an arbitrary Lisp expression evaluated at replacement

can be edited for each replacement.
++++
** query-replace uses isearch lazy highlighting when the new user option
`query-replace-lazy-highlight' is non-nil.
+---
** The current match in query-replace is highlighted in new face
`query-replace' which by default inherits from isearch face.
You can go back to that backup value by selecting "Use Backup Value"
under the "[State]" button.
+---
** The new customization type `float' specifies numbers with floating
point (no integers are allowed).
previous mark, i.e. C-u C-SPC C-SPC C-SPC ... cycles through the
mark ring. Use C-u C-u C-SPC to set the mark immediately after a jump.
++++
** Movement commands `beginning-of-buffer', `end-of-buffer',
`beginning-of-defun', `end-of-defun' do not set the mark if the mark
is already active in Transient Mark mode.
** mouse-wheels can now scroll a specific fraction of the window
(rather than a fixed number of lines) and the scrolling is `progressive'.
+---
** Unexpected yanking of text due to accidental clicking on the mouse
wheel button (typically mouse-2) during wheel scrolling is now avoided.
This behavior can be customized via the mouse-wheel-click-event and
of `cursor-in-non-selected-windows' in the buffer that the cursor
appears in.
++++
** The variable `cursor-in-non-selected-windows' can now be set to any
of the recognized cursor types.
`appt-display-format' controls how reminders are displayed, replacing
appt-issue-message, appt-visible, and appt-msg-window.
++++
** The new functions `diary-from-outlook', `diary-from-outlook-gnus',
and `diary-from-outlook-rmail' can be used to import diary entries
from Outlook-format appointments in mail messages. The variable
allows you to specify a compression level using the "-z#" option for
CVS.
++++
*** New backends for Subversion and Meta-CVS.
** EDiff changes.
The function c-toggle-syntactic-indentation can be used to toggle
syntactic indentation.
++++
** The command line option --no-windows has been changed to
--no-window-system. The old one still works, but is deprecated.
Adapt this to match the format of any compiler directives you use.
Lines that match are never indented, and are given distinctive font-locking.

** F90 mode has new navigation commands `f90-end-of-block',
`f90-beginning-of-block', `f90-next-block', `f90-previous-block'.
