windows版本的emacs

versions of emacs to make the mode-line stand out, is now deprecated.
However, setting it to nil will cause the `mode-line' face to be
ignored, and mode-lines to be drawn using the default text face.

** Mouse-sensitive mode line.

Different parts of the mode line have been made mouse-sensitive on all
systems which support the mouse.  Moving the mouse to a
mouse-sensitive part in the mode line changes the appearance of the
mouse pointer to an arrow, and help about available mouse actions is
displayed either in the echo area, or in the tooltip window if you
have enabled one.

Currently, the following actions have been defined:

- Mouse-1 on the buffer name in the mode line goes to the next buffer.

- Mouse-3 on the buffer-name goes to the previous buffer.

- Mouse-2 on the read-only or modified status in the mode line (`%' or
`*') toggles the status.

- Mouse-3 on the mode name displays a minor-mode menu.

** Hourglass pointer

Emacs can optionally display an hourglass pointer under X.  You can
turn the display on or off by customizing group `cursor'.

** Blinking cursor

M-x blink-cursor-mode toggles a blinking cursor under X and on
terminals having terminal capabilities `vi', `vs', and `ve'.  Blinking
and related parameters like frequency and delay can be customized in
the group `cursor'.

** New font-lock support mode `jit-lock-mode'.

This support mode is roughly equivalent to `lazy-lock' but is
generally faster.  It supports stealth and deferred fontification.
See the documentation of the function `jit-lock-mode' for more
details.

Font-lock uses jit-lock-mode as default support mode, so you don't
have to do anything to activate it.

** The default binding of the Delete key has changed.

The new user-option `normal-erase-is-backspace' can be set to
determine the effect of the Delete and Backspace function keys.

On window systems, the default value of this option is chosen
according to the keyboard used.  If the keyboard has both a Backspace
key and a Delete key, and both are mapped to their usual meanings, the
option's default value is set to t, so that Backspace can be used to
delete backward, and Delete can be used to delete forward.  On
keyboards which either have only one key (usually labeled DEL), or two
keys DEL and BS which produce the same effect, the option's value is
set to nil, and these keys delete backward.

If not running under a window system, setting this option accomplishes
a similar effect by mapping C-h, which is usually generated by the
Backspace key, to DEL, and by mapping DEL to C-d via
`keyboard-translate'.  The former functionality of C-h is available on
the F1 key.  You should probably not use this setting on a text-only
terminal if you don't have both Backspace, Delete and F1 keys.

Programmatically, you can call function normal-erase-is-backspace-mode
to toggle the behavior of the Delete and Backspace keys.

** The default for user-option `next-line-add-newlines' has been
changed to nil, i.e. C-n will no longer add newlines at the end of a
buffer by default.

** The <home> and <end> keys now move to the beginning or end of the
current line, respectively.  C-<home> and C-<end> move to the
beginning and end of the buffer.

** Emacs now checks for recursive loads of Lisp files.  If the
recursion depth exceeds `recursive-load-depth-limit', an error is
signaled.

** When an error is signaled during the loading of the user's init
file, Emacs now pops up the *Messages* buffer.

** Emacs now refuses to load compiled Lisp files which weren't
compiled with Emacs.  Set `load-dangerous-libraries' to t to change
this behavior.

The reason for this change is an incompatible change in XEmacs's byte
compiler.  Files compiled with XEmacs can contain byte codes that let
Emacs dump core.

** Toggle buttons and radio buttons in menus.

When compiled with LessTif (or Motif) support, Emacs uses toolkit
widgets for radio and toggle buttons in menus.  When configured for
Lucid, Emacs draws radio buttons and toggle buttons similar to Motif.

** The menu bar configuration has changed.  The new configuration is
more CUA-compliant.  The most significant change is that Options is
now a separate menu-bar item, with Mule and Customize as its submenus.

** Item Save Options on the Options menu allows saving options set
using that menu.

** Highlighting of trailing whitespace.

When `show-trailing-whitespace' is non-nil, Emacs displays trailing
whitespace in the face `trailing-whitespace'.  Trailing whitespace is
defined as spaces or tabs at the end of a line.  To avoid busy
highlighting when entering new text, trailing whitespace is not
displayed if point is at the end of the line containing the
whitespace.

** C-x 5 1 runs the new command delete-other-frames which deletes
all frames except the selected one.

** The new user-option `confirm-kill-emacs' can be customized to
let Emacs ask for confirmation before exiting.

** The header line in an Info buffer is now displayed as an emacs
header-line (which is like a mode-line, but at the top of the window),
so that it remains visible even when the buffer has been scrolled.
This behavior may be disabled by customizing the option
`Info-use-header-line'.

** Polish, Czech, German, and French translations of Emacs' reference card
have been added.  They are named `pl-refcard.tex', `cs-refcard.tex',
`de-refcard.tex' and `fr-refcard.tex'.  Postscript files are included.

** An `Emacs Survival Guide', etc/survival.tex, is available.

** A reference card for Dired has been added.  Its name is
`dired-ref.tex'.  A French translation is available in
`fr-drdref.tex'.

** C-down-mouse-3 is bound differently.  Now if the menu bar is not
displayed it pops up a menu containing the items which would be on the
menu bar.  If the menu bar is displayed, it pops up the major mode
menu or the Edit menu if there is no major mode menu.

** Variable `load-path' is no longer customizable through Customize.

You can no longer use `M-x customize-variable' to customize `load-path'
because it now contains a version-dependent component.  You can still
use `add-to-list' and `setq' to customize this variable in your
`~/.emacs' init file or to modify it from any Lisp program in general.

** C-u C-x = provides detailed information about the character at
point in a pop-up window.

** Emacs can now support 'wheeled' mice (such as the MS IntelliMouse)
under XFree86.  To enable this, use the `mouse-wheel-mode' command, or
customize the variable `mouse-wheel-mode'.

The variables `mouse-wheel-follow-mouse' and `mouse-wheel-scroll-amount'
determine where and by how much buffers are scrolled.

** Emacs' auto-save list files are now by default stored in a
sub-directory `.emacs.d/auto-save-list/' of the user's home directory.
(On MS-DOS, this subdirectory's name is `_emacs.d/auto-save.list/'.)
You can customize `auto-save-list-file-prefix' to change this location.

** The function `getenv' is now callable interactively.

** The new user-option `even-window-heights' can be set to nil
to prevent `display-buffer' from evening out window heights.

** The new command M-x delete-trailing-whitespace RET will delete the
trailing whitespace within the current restriction.  You can also add
this function to `write-file-hooks' or `local-write-file-hooks'.

** When visiting a file with M-x find-file-literally, no newlines will
be added to the end of the buffer even if `require-final-newline' is
non-nil.

** The new user-option `find-file-suppress-same-file-warnings' can be
set to suppress warnings ``X and Y are the same file'' when visiting a
file that is already visited under a different name.

** The new user-option `electric-help-shrink-window' can be set to
nil to prevent adjusting the help window size to the buffer size.

** New command M-x describe-character-set reads a character set name
and displays information about that.

** The new variable `auto-mode-interpreter-regexp' contains a regular
expression matching interpreters, for file mode determination.

This regular expression is matched against the first line of a file to
determine the file's mode in `set-auto-mode' when Emacs can't deduce a
mode from the file's name.  If it matches, the file is assumed to be
interpreted by the interpreter matched by the second group of the
regular expression.  The mode is then determined as the mode
associated with that interpreter in `interpreter-mode-alist'.

** New function executable-make-buffer-file-executable-if-script-p is
suitable as an after-save-hook as an alternative to `executable-chmod'.

** The most preferred coding-system is now used to save a buffer if
buffer-file-coding-system is `undecided' and it is safe for the buffer
contents.  (The most preferred is set by set-language-environment or
by M-x prefer-coding-system.)  Thus if you visit an ASCII file and
insert a non-ASCII character from your current language environment,
the file will be saved silently with the appropriate coding.
Previously you would be prompted for a safe coding system.

** The many obsolete language `setup-...-environment' commands have
been removed -- use `set-language-environment'.

** The new Custom option `keyboard-coding-system' specifies a coding
system for keyboard input.

** New variable `inhibit-iso-escape-detection' determines if Emacs'
coding system detection algorithm should pay attention to ISO2022's
escape sequences.  If this variable is non-nil, the algorithm ignores
such escape sequences.  The default value is nil, and it is
recommended not to change it except for the special case that you
always want to read any escape code verbatim.  If you just want to
read a specific file without decoding escape codes, use C-x RET c
(`universal-coding-system-argument').  For instance, C-x RET c latin-1
RET C-x C-f filename RET.

** Variable `default-korean-keyboard' is initialized properly from the
environment variable `HANGUL_KEYBOARD_TYPE'.

** New command M-x list-charset-chars reads a character set name and
displays all characters in that character set.

** M-x set-terminal-coding-system (C-x RET t) now allows CCL-based
coding systems such as cpXXX and cyrillic-koi8.

** Emacs now attempts to determine the initial language environment
and preferred and locale coding systems systematically from the
LC_ALL, LC_CTYPE, and LANG environment variables during startup.

** New language environments `Polish', `Latin-8' and `Latin-9'.
Latin-8 and Latin-9 correspond respectively to the ISO character sets
8859-14 (Celtic) and 8859-15 (updated Latin-1, with the Euro sign).
GNU Intlfonts doesn't support these yet but recent X releases have
8859-15.  See etc/INSTALL for information on obtaining extra fonts.
There are new Leim input methods for Latin-8 and Latin-9 prefix (only)
and Polish `slash'.

** New language environments `Dutch' and `Spanish'.
These new environments mainly select appropriate translations
of the tutorial.

** In Ethiopic language environment, special key bindings for
function keys are changed as follows.  This is to conform to "Emacs
Lisp Coding Convention".

    new  command                            old-binding
    ---  -------                            -----------
    f3   ethio-fidel-to-sera-buffer         f5
    S-f3 ethio-fidel-to-sera-region         f5
    C-f3 ethio-fidel-to-sera-mail-or-marker f5

    f4   ethio-sera-to-fidel-buffer         unchanged
    S-f4 ethio-sera-to-fidel-region         unchanged
    C-f4 ethio-sera-to-fidel-mail-or-marker unchanged

    S-f5 ethio-toggle-punctuation           f3
    S-f6 ethio-modify-vowel                 f6
    S-f7 ethio-replace-space                f7
    S-f8 ethio-input-special-character      f8
    S-f9 ethio-replace-space                unchanged
    C-f9 ethio-toggle-space                 f2

** There are new Leim input methods.
New input methods "turkish-postfix", "turkish-alt-postfix",
"greek-mizuochi", "TeX", and "greek-babel" are now part of the Leim
package.

** The rule of input method "slovak" is slightly changed.  Now the
rules for translating "q" and "Q" to "`" (backquote) are deleted, thus
typing them inserts "q" and "Q" respectively.  Rules for translating
"=q", "+q", "=Q", and "+Q" to "`" are also deleted.  Now, to input
"`", you must type "=q".

** If your terminal can't display characters from some of the ISO
8859 character sets but can display Latin-1, you can display
more-or-less mnemonic sequences of ASCII/Latin-1 characters instead of
empty boxes (under a window system) or question marks (not under a
window system).  Customize the option `latin1-display' to turn this
on.

** M-; now calls comment-dwim which tries to do something clever based
on the context.  M-x kill-comment is now an alias to comment-kill,
defined in newcomment.el.  You can choose different styles of region
commenting with the variable `comment-style'.

** New user options `display-time-mail-face' and
`display-time-use-mail-icon' control the appearance of mode-line mail
indicator used by the display-time package.  On a suitable display the
indicator can be an icon and is mouse-sensitive.

** On window-systems, additional space can be put between text lines
on the display using several methods

- By setting frame parameter `line-spacing' to PIXELS.  PIXELS must be
a positive integer, and specifies that PIXELS number of pixels should
be put below text lines on the affected frame or frames.

- By setting X resource `lineSpacing', class `LineSpacing'.  This is
equivalent to specifying the frame parameter.

- By specifying `--line-spacing=N' or `-lsp N' on the command line.

- By setting buffer-local variable `line-spacing'.  The meaning is
the same, but applies to the a particular buffer only.
