8 For those users who live backwards in time, here is information about
9 downgrading to Emacs version 21.4. We hope you will enjoy the greater
10 simplicity that results from the absence of many Emacs 22 features.
15 The buffer position and line number are now displayed at the end of
16 the mode line, where they can be more easily seen.
19 The mode line of the selected window is no longer displayed with a
20 special face. All mode lines are created equal.
23 Clicking on a link with the left mouse button (@kbd{mouse-1}) will
24 always set point at the position clicked, instead of following the
25 link. If you want to follow the link, use the middle mouse button
29 Emacs is tired of X droppings. If you drop a file or a piece of text
30 onto an Emacs window, nothing will happen.
33 On an xterm, Emacs provides a more convincing simulation of a text
34 terminal by not responding to mouse-clicks on the mode-line,
35 header-line, or display margin.
38 For simplicity, windows always have fringes. We wouldn't want to
39 in-fringe anyone's windows. Likewise, horizontal scrolling always
40 works in the same automatic way.
43 The horizontal-bar cursor shape has been removed.
46 If command line arguments are given, Emacs will not display a splash
47 screen, so that you can immediately get on with your editing. The
48 command-line option @samp{--no-splash} is therefore obsolete, and has
52 The command line options @samp{--color}, @samp{--fullwidth},
53 @samp{--fullheight}, @samp{--fullscreen}, @samp{--no-blinking-cursor},
54 @samp{--no-desktop}, and @samp{-Q} have also been removed.
57 The @samp{--geometry} option applies only to the initial frame, and
58 the @samp{-f} option will not read arguments for interactive
62 Emacs now looks for @file{.emacs} and @file{.emacs_SHELL} in one
63 standard location---your home directory. Don't put these files in
64 @file{~/.emacs.d}; they won't be found.
67 Emacs will not read @file{~/.abbrev_defs} automatically. If you want
68 to load abbrev definitions from a file, you must always do so
72 When you are logged in as root, all files now give you writable
73 buffers, reflecting the fact that you can write any files.
76 The maximum size of buffers and integer variables has been halved. On
77 32-bit machines, the maximum buffer size is now 128 megabytes.
80 An unquoted @samp{$} in a file name is now an error, if the following
81 name is not recognized as an environment variable. Thus,
82 the file name @file{foo$bar} would probably be an error. Meanwhile,
83 the @code{setenv} command does not expand @samp{$} at all.
86 Emacs will not query you if a command accumulates too much undo
87 information. If Emacs runs out of memory as a result, it will handle
91 Many commands have been removed from the menus or rearranged.
94 The @kbd{C-h} (help) subcommands have been rearranged---especially
95 those that display specific files. Type @kbd{C-h C-h} to see a list
96 of these commands; that will show you what is different.
99 The @kbd{C-h v} and @kbd{C-h f} commands no longer show a hyperlink to
100 the C source code, even if it is available. If you want to find the
101 source code, grep for it.
104 The apropos commands will not accept a list of words to match, in
105 order to encourage users to be more specific. Also, the user option
106 @code{apropos-sort-by-scores} has been removed.
109 The minibuffer prompt is now displayed using the default face.
110 The colon is enough to show you what part is the prompt.
113 Minibuffer completion commands always complete the entire minibuffer
114 contents, just as if you had typed them at the end of the minibuffer,
115 no matter where point is actually located.
118 The command @code{backward-kill-sexp} is now bound to @kbd{C-M-delete}
119 and @kbd{C-M-backspace}. Be careful when using these key sequences!
120 It may shut down your X server, or reboot your operating system.
123 Commands to set the mark at a place away from point, including
124 @kbd{M-@@}, @kbd{M-h}, etc., don't do anything special when you repeat
125 them. In most cases, typing these commands multiple times is
126 equivalent to typing them once. @kbd{M-h} ignores numeric arguments.
129 If you want to repeat a jump to a previous mark, you should supply the
130 prefix argument explicitly. So, instead of typing @kbd{C-u C-SPC
131 C-SPC C-SPC}, type @kbd{C-u C-SPC C-u C-SPC C-u C-SPC}.
134 @kbd{C-@key{SPC} C-@key{SPC}} has no special meaning--it just sets the
135 mark twice. Neither does @kbd{C-u C-x C-x}, which simply exchanges
136 point and mark like @kbd{C-x C-x}.
139 The function @code{sentence-end} has been eliminated in favor of a
140 more straightforward approach: directly setting the variable
141 @code{sentence-end}. For example, to end each sentence with a single
145 (setq sentence-end "[.?!][]\"')@}]*\\($\\|[ \t]\\)[ \t\n]*")
149 The variable @code{fill-nobreak-predicate} is no longer customizable,
150 and it can only hold a single function.
153 Non-breaking spaces and hyphens are displayed just like normal
154 characters. The user option @code{show-nonbreak-escape} is therefore
155 obsolete, and has been removed.
158 @kbd{C-w} in an incremental search always grabs an entire word
159 into the search string. More precisely, it grabs text through
160 the next end of a word.
163 Yanking now preserves all text properties that were in the killed
164 text. The variable @code{yank-excluded-properties} has been removed.
167 Occur mode, Info mode, and Comint-derived modes now control
168 fontification in their own way, and @kbd{M-x font-lock-mode} has
169 nothing to do with it. To control fontification in Info mode, use the
170 variable @code{Info-fontify}.
173 The Grep package has been merged with Compilation mode. Many
174 grep-specific commands and user options have thus been eliminated.
175 Also, @kbd{M-x grep} never tries the GNU grep @samp{-H} option,
176 and instead silently appends @file{/dev/null} to the command line.
179 In Dired's @kbd{!} command, @samp{*} and @samp{?} now
180 cause substitution of the file names wherever they appear---not
181 only when they are surrounded by whitespace.
184 When a file is managed with version control, the command @kbd{C-x C-q}
185 (whose general meaning is to make a buffer read-only or writable) now
186 does so by checking the file in or out. Checking the file out makes
187 the buffer writable; checking it in makes the buffer read-only.
189 You can still use @kbd{C-x v v} to do these operations if you wish;
190 its meaning is unchanged. If you want to control the buffer's
191 read-only flag without performing any version control operation,
192 use @kbd{M-x toggle-read-only}.
195 SGML mode does not handle XML syntax, and does not have indentation
199 Many Info mode commands have been removed. Incremental search in Info
200 searches only the current node.
203 Many @code{etags} features for customizing parsing using regexps
207 The Emacs server now runs a small C program called @file{emacsserver},
208 rather than trying to handle everything in Emacs Lisp. Now there can
209 only be one Emacs server running at a time. The @code{server-mode}
210 command and @code{server-name} user option have been eliminated.
213 The @file{emacsclient} program no longer accepts the @samp{--eval} and
214 @samp{--display} command line options.
217 The command @code{quail-show-key}, for showing how to input a
218 character, has been removed.
221 The default value of @code{keyboard-coding-system} is always
222 @code{nil}, regardless of your locale settings. If you want some
223 other value, set it yourself.
226 Unicode support and unification between Latin-@var{n} character sets
227 have been removed. Cutting and pasting X selections does not support
228 ``extended segments'', so there are certain coding systems it cannot
232 The input methods for Emacs are included in a separate distribution
233 called ``Leim''. To use this, you must extract the Leim tar file on
234 top of the Emacs distribution, into the same directory, before you
238 The following input methods have been eliminated: belarusian,
239 bulgarian-bds, bulgarian-phonetic, chinese-sisheng, croatian, dutch,
240 georgian, latin-alt-postfix, latin-postfix, latin-prefix,
241 latvian-keyboard, lithuanian-numeric, lithuanian-keyboard,
242 malayalam-inscript, rfc1345, russian-computer, sgml, slovenian,
243 tamil-inscript ucs, ukrainian-computer, vietnamese-telex, and welsh.
246 The following language environments have been eliminated: Belarusian,
247 Bulgarian, Chinese-EUC-TW, Croatian, French, Georgian, Italian,
248 Latin-6, Latin-7, Latvian, Lithuanian, Malayalam, Russian, Russian,
249 Slovenian, Swedish, Tajik, Tamil, UTF-8, Ukrainian, Ukrainian, Welsh,
253 The @code{code-pages} library, which contained various 8-bit coding
254 systems, has been removed.
257 The Kmacro package has been replaced with a simple and elegant
258 keyboard macro system. Use @kbd{C-x (} to start a new keyboard macro,
259 @kbd{C-x )} to end the macro, and @kbd{C-x e} to execute the last
263 The Calc, CUA, GDB-UI, Ibuffer, Ido, Password, Printing, Reveal,
264 Ruler-mode, SES, Table, Tramp, and URL packages have been removed.
265 The Benchmark, Cfengine, Conf, Dns, Flymake, Python, Thumbs, and
266 Wdired modes have also been removed.
269 The Emacs Lisp Reference Manual and the Introduction to Programming in
270 Emacs Lisp are now distributed separately, not in the Emacs
274 On MS Windows, there is no longer any support for tooltips, images,
275 sound, different mouse pointer shapes, or pointing devices with more
276 than 3 buttons. If you want these features, consider switching to
277 another operating system. But even if you don't want these features,
278 you should still switch---for freedom's sake.
281 Emacs will not use Unicode for clipboard operations on MS Windows.
284 To keep up with decreasing computer memory capacity and disk space, many
285 other functions and files have been eliminated in Emacs 21.4.
