33 | ** New font code. |
34 | Fonts are handled by new code capable of dealing with multiple font | |
de9efca0 | 35 | backends. This uses the freetype and fontconfig libraries. |
50e54fba | 36 | +++ |
09e18d03 CY |
37 | *** Emacs now accepts font names supplied in the fontconfig format |
38 | (e.g. "monospace-12:bold") and GTK format (e.g. "Monospace Bold 12"). | |

1e9b0fb2 | 61 | OS X (via the Cocoa libraries). |
043023ca CY |
62 | |
63 | Specify --with-ns to configure for this. By default, a self-contained | |
64 | app will be built (containing all lisp). To install/share lisp with | |
65 | other emacsen (e.g. X11 build) use --disable-ns-self-contained. See | |
66 | nextstep/README and nextstep/INSTALL in the Emacs source directory. | |
006a2cde CY |

85 | emacs-devel@gnu.org to inform the Emacs developers. | |
006a2cde | 86 | |
9bc072cc | 87 | *** Old GNU/Linux systems based on libc version 5. |
006a2cde | 88 | |

92 | *** Solaris versions 2.6 and below. | |
93 | ||
32847230 CY |
94 | *** Solaris on IBM RS6000 machines. |

98 | *** Unixware on non-x86 machines. |
99 | ||
32847230 CY |

104 | ** The configure options `--with-gcc', `--without-gcc' have been removed. |
105 | Configure will use gcc by default. Set the CC environment variable if | |
106 | you need control over which C compiler is used. | |

09e18d03 | 121 | ** Improved X Window System support |
c409d2f3 | 122 | +++ |
09e18d03 CY |
123 | *** Emacs now supports using both X displays and ttys in one session. |
124 | With an Emacs server active (M-x server-start), `emacsclient -t' | |
125 | creates a tty frame connected to the running emacs server. You can | |
126 | use any number of different ttys. `emacsclient -c' creates a new X11 | |
127 | frame on the current $DISPLAY (or a tty frame if $DISPLAY is not set). | |
780d7bb9 RS |
128 | |
129 | You can test for the presence of this feature in your Lisp code by | |
130 | testing for the `multi-tty' feature. | |
c409d2f3 | 131 | +++ |
eab2ee89 DN |
132 | *** Emacs can now start in background, as a daemon when using the |
133 | --daemon command line argument. It disconnects from the terminal and | |
134 | starts the server. Clients can connect and create graphical or | |
135 | terminal frames using emacsclient. | |
136 | ||
c569485c | 137 | **** emacsclient starts emacs in daemon mode and connects to it when |
82d0a250 DN |
138 | --alternate-editor="" is used (or when the evironment variable |
139 | ALTERNATE_EDITOR is set to "") and emacsclient cannot connect to an | |
c569485c DN |
140 | emacs server. |
141 | ||
09e18d03 | 142 | *** The new command close-display-connection closes a connection to a |
717c97e5 | 143 | remote display. There are some bugs for Gtk+. See etc/PROBLEMS. |
d82c3d44 | 144 | |
09e18d03 CY |
145 | *** Emacs now supports the XEmbed specification. |
146 | You can embed Emacs in another application on X11. The new command line | |
147 | option --parent-id is used to pass the parent window id to Emacs. See | |
7b476dbe JD |
148 | http://standards.freedesktop.org/xembed-spec/xembed-spec-latest.html |
149 | for details about XEmbed. | |
7b2b8557 | 150 | +++ |
09e18d03 CY |
151 | *** Emacs can now set the frame opacity. |
152 | The opacity of a frame can be controlled by setting the `alpha' frame | |
153 | parameter. This only takes effect on a compositing window manager for | |
920ab46c SZ |
154 | the X Window System, such as Compiz, Beryl and Compiz Fusion, on Mac |
155 | OS X, or on Windows 2000 and later versions of Windows. | |
55f9bad5 GM |
156 | |
157 | The alpha parameter should be an integer between 0 (transparent) and | |
09e18d03 CY |
158 | 100 (opaque), or a float number between 0.0 and 1.0. It can also be a |
159 | cons cell (ACTIVE . INACTIVE), where ACTIVE is the opacity of an | |
160 | active frame and INACTIVE is the opactity of non-active frames. | |
55f9bad5 | 161 | |
09e18d03 CY |
162 | The variable `frame-alpha-lower-limit' defines a lower bound for the |
163 | opacity; the default is 20. | |
55f9bad5 | 164 | |
09e18d03 | 165 | ** Internationalization changes |
fec8ef06 | 166 | |
09e18d03 CY |
167 | *** The Emacs character set is now a superset of Unicode. |
168 | (It has about four times the code space, which should be plenty). | |
0a963185 | 169 | |
09e18d03 CY |
170 | The internal encoding used for buffers and strings is now |
171 | Unicode-based and called `utf-8-emacs'. This encoding is backwards | |
172 | compatible with Unicode's UTF-8 encoding. The internal encoding | |
173 | previously used by Emacs, `emacs-mule', is still available. | |
6dadd99f | 174 | |
09e18d03 CY |
175 | During byte-compilation, Emacs 23 uses `utf-8-emacs' to write files. |
176 | As a result, byte-compiled files containing non-ASCII characters can't | |
177 | be read by earlier versions of Emacs. Files compiled by Emacs 20, 21, | |
178 | or 22 are loaded correctly as emacs-mule (whether or not they contain | |
179 | multibyte characters). This takes somewhat more time, so it may be | |
180 | worth recompiling existing .elc files which don't need to be shared | |
181 | with older Emacsen. | |
3ae459e5 | 182 | |
09e18d03 | 183 | *** There are new coding systems/aliases; see M-x list-coding-systems. |
c2e8590b | 184 | |
09e18d03 CY |
185 | *** There is a new charset implementation with many new charsets. |
186 | See M-x list-character-sets. New charsets can be defined conveniently | |
187 | as tables of unicodes. | |
1abe3a1e | 188 | |
09e18d03 CY |
189 | **** The dimension of a charset is now 1, 2, 3, or 4, and the size of |
190 | each dimension is no longer limited to 94 or 96. | |
eb28688c | 191 | |
09e18d03 CY |
192 | **** A dynamic charset priority list is used to infer the charset of |
193 | characters for display. | |
6c5d503f | 194 | |
09e18d03 CY |
195 | *** There are new language environments for Chinese-GBK, |
196 | Chinese-GB18030, Khmer, Bengali, Punjabi, Gujarati, Oriya, Telugu, | |
197 | Sinhala, and TaiViet. | |
c9447ae1 | 198 | |
09e18d03 CY |
199 | *** The minor modes unify-8859-on-encoding-mode and |
200 | unify-8859-on-decoding-mode are obsolete. | |
d466e9fc | 201 | |
e94d0645 JL |
202 | *** `ucs-insert' is bound to `C-x 8 RET' and in addition to hex numbers |
203 | accepts numbers in hash notation (e.g. #o21430 for octal, or #10r8984 for | |
204 | decimal). It also accepts Unicode character names with completion. | |
205 | ||
6d496c76 TZ |
206 | *** The `cyrillic-translit' input method supports many new characters. |
207 | Common typographical characters available from Unicode were added to | |
208 | `cyrillic-translit': punctuation marks, accented characters, fractions, | |
209 | and others. | |
210 | ||
09e18d03 | 211 | ** Emacs now supports serial port access on GNU/Linux, Unix, and |
81efacf9 CY |
212 | Windows. The new command `serial-term' starts an interactive terminal |
213 | on a serial port. The serial port can be configured at runtime with | |
214 | the mode-line mouse menu. | |
6c5d503f | 215 | |
09e18d03 | 216 | ** Menu Bar changes |
81efacf9 | 217 | --- |
09e18d03 CY |
218 | *** In the Options menu, the "Set Default Font" item applies the |
219 | selected font to the `default' face on all frames, not just the | |
220 | current frame. Furthermore, if Emacs is compiled with both GTK and | |
221 | Fontconfig support, the "Set Default Font" item uses the GTK font | |
222 | selection dialog instead of an Emacs pop-up menu. | |
81efacf9 | 223 | --- |
09e18d03 CY |
224 | *** The font setting chosen by "Set Default Font" is saved if the |
225 | "Save Options" item is used. | |
1b21ee06 | 226 | |
b350bdf2 CY |
227 | *** The Tools menu contains a new Encryption/Decryption submenu. |
228 | This contains commands provided by EasyPG, the newly-included | |
229 | interface to GnuPG (see New Modes and Packages). | |
81efacf9 CY |
230 | --- |
231 | *** In the Options menu, the "Truncate Long Lines in the Buffer" entry | |
232 | has been replaced with a submenu offering three different ways to | |
233 | handle long lines: truncation, continuation at the window edge, and | |
697f6b43 | 234 | the new word wrapping behavior (see Editing Changes, below). |
c37fd4ed | 235 | --- |
c1337511 DN |
236 | *** Improvements to menus for major and minor modes |
237 | More major and minor modes now have a mode specific menu, and existing | |
238 | mode menus have been improved to include more functionality. | |
239 | ||
09e18d03 | 240 | ** Mode-line changes |
a6b85944 | 241 | +++ |
09e18d03 CY |
242 | *** The mode-line displays a `@', instead of `-', if the |
243 | default-directory for the current buffer is on a remote machine. | |
6c8ad8f7 | 244 | --- |
09e18d03 CY |
245 | *** The mode-line displays a mode menu when mouse-1 is clicked on a |
246 | minor mode, in the same way as it already did for major modes. | |
c37fd4ed | 247 | --- |
09e18d03 CY |
248 | *** The `mode-line-emphasis' face is used to highlight certain |
249 | mode-line information (e.g. waiting for a VC command to finish). | |
6c8ad8f7 | 250 | --- |
c1337511 | 251 | *** The mode-line tooltips have been improved to provide more details. |
04e6cfff | 252 | +++ |
c1337511 DN |
253 | *** The VC, line/colum number and minor mode indicators on the mode |
254 | line are now interactive: mouse-1 can be used on them to pop up a menu. | |

257 | ** File deletion can make use of the Recycle Bin or system Trash folder. |
258 | Set `delete-by-moving-to-trash' non-nil to use this. Deleted files | |
0956be4f | 259 | and directories will then be sent to the Recycle Bin on Windows, and |
b798e26a GM |

d91c8dd8 | 262 | +++ |
09e18d03 | 263 | ** Directory-local variables can now be defined. |
fc0318c6 JL |
264 | By default, Emacs looks in .dir-locals.el for directory-local |
265 | variables. For more information, see `dir-locals-set-directory-class' | |
266 | and `dir-locals-set-class-variables'. | |
307f3501 | 267 | |
b798e26a GM |
268 | ** Emacs can now use `auth-source' for authentication. |
269 | `smtpmail' and `url' (Tramp and Gnus also) use `auth-source' to obtain | |
270 | login names and passwords. The match, if found, is reported | |
271 | in *Messages* with the password blanked out. | |

3063e326 JL |
279 | ** The option `inhibit-startup-screen' (with aliases to old names |
280 | `inhibit-splash-screen' and `inhibit-startup-message') doesn't inhibit | |
281 | display of the initial message in the *scratch* buffer. If you don't | |
282 | want to display the initial message in the *scratch* buffer at startup, | |

697f6b43 | 354 | +++ |
0c8b58e9 CY |
355 | ** The C-n and C-p line-motion commands now move by screen lines, |
356 | taking continued lines and variable-width characters into account. | |
357 | Setting `line-move-visual' to nil reverts this to the previous | |
358 | behavior (motion by logical lines based on buffer contents alone). | |
359 | ||
1d3b3736 | 360 | +++ |
09e18d03 CY |
361 | ** C-x C-c now invokes `save-buffers-kill-terminal', and C-z now |
362 | invokes `suspend-frame'. This change is for compatibility with the | |
363 | new multi-tty support (see `Improved X Window System support' above). | |
3ae459e5 | 364 | |
09e18d03 | 365 | ** Mark changes |
59b5d020 | 366 | +++ |
3ae459e5 | 367 | *** Transient Mark mode is now on by default. |
3ae459e5 CY |
368 | +++ |
369 | *** mark-even-if-inactive now defaults to t | |
3ae459e5 | 370 | +++ |
b350bdf2 CY |
371 | *** When Transient Mark mode is on, C-SPC C-SPC pushes a mark without |
372 | activating it. | |
1ac03a31 | 373 | +++ |
3ae459e5 CY |
374 | *** When Transient Mark mode is on, M-q now fills the region if the |
375 | region is active. Otherwise, it fills the current paragraph. | |
ecde850a | 376 | +++ |
3ae459e5 CY |
377 | *** When Transient Mark mode is on, M-$ now checks spelling of the |
378 | region if the region is active. Otherwise, it checks spelling of the | |
dc868f13 | 379 | word at point. |
46875066 | 380 | +++ |
3ae459e5 CY |
381 | *** When Transient Mark mode is on, TAB now indents the region if the |
382 | region is active. | |
c417ddc2 | 383 | +++ |
3ae459e5 CY |
384 | *** `use-empty-active-region' controls whether an empty active region |
385 | in Transient Mark mode should make commands operate on that empty | |
386 | region. | |
387 | ||
388 | ** Temporarily active regions | |
4502d15f | 389 | +++ |
3ae459e5 CY |
390 | *** The new variable shift-select-mode, non-nil by default, controls |
391 | shift-selection. When Shift Select mode is on, shift-translated | |
392 | motion keys (e.g. S-left and S-down) activate and extend a temporary | |
393 | region, similar to mouse-selection. | |
4502d15f | 394 | +++ |
3ae459e5 CY |
395 | *** Temporarily active regions, created using shift-selection or |
396 | mouse-selection, are not necessarily deactivated in the next command. | |
397 | They are only deactivated after point motion commands that are not | |
398 | shift-translated, or after commands that would ordinarily deactivate | |
399 | the mark in Transient Mark mode (e.g., any command that modifies the | |
400 | buffer). | |
401 | ||
3307af6c | 402 | ** Minibuffer and completion changes |
0ca1ad68 | 403 | +++ |
206faa92 CY |
404 | *** Emacs may ask for confirmation before opening a non-existent file |
405 | or buffer. By default, Emacs requests confirmation if you type RET | |
406 | immediately after TAB, and the resulting input is not an existing file | |
407 | or buffer; this usually happens when the minibuffer input did not | |
408 | complete far enough and you entered RET by mistake. In that case, | |
409 | Emacs puts the message "[Confirm]" in the minibuffer; type RET again | |
410 | to create the file or buffer. | |
411 | ||
412 | The new variable confirm-nonexistent-file-or-buffer determines whether | |
413 | Emacs asks for confirmation. The default value is `after-completion'. | |
414 | If you change it to t, Emacs always asks for confirmation; if you | |
415 | change it to nil, Emacs never asks for confirmation. | |
416 | +++ | |
d47a29c1 JL |
417 | *** When M-n in the minibuffer reaches the end of the list of defaults, |
418 | it adds the completion list to the end, so next M-n continues putting | |
419 | completion items to the minibuffer. The same principle applies to | |
420 | incremental search commands as well: C-s or C-M-s starts searching | |
421 | the default values and after the end of defaults they continue | |
422 | searching minibuffer completion items. | |
3c241617 | 423 | --- |
09e18d03 | 424 | *** Minibuffer input of shell commands now comes with completion. |
0999a3f4 | 425 | +++ |
09e18d03 CY |
426 | *** In the `C-x d' (Dired) prompt, typing M-n gives the visited file |
427 | name of the current buffer. | |
dc2f6c05 | 428 | |
09e18d03 CY |
429 | *** In the M-! (shell-command) prompt, M-n provides some default commands. |
430 | These are guessed using the file extension of the current file, based | |
431 | on the file-handlers specified in the operating system's `mailcap' | |
432 | file. The ! command in Dired (dired-do-shell-command) works | |
433 | similarly, using the file displayed on the current line. | |
117907d4 JL |
434 | |
435 | *** A list of regexp default values is available via M-n for `occur', | |
436 | `keep-lines', `flush-lines' and `how-many'. This list includes the active | |
4f75e082 JL |
437 | region in transient-mark-mode, the word under the cursor, the last Isearch |
438 | regexp, the last Isearch string and the last replacement regexp. | |
c4e606b6 | 439 | --- |
3353f870 CY |
440 | *** When enable-recursive-minibuffers is non-nil, operations which use |
441 | switch-to-buffer (such as C-x b and C-x C-f) do not fail any more when | |
442 | used in a minibuffer or a dedicated window. Instead, they fallback on | |
443 | using pop-to-buffer, which will use some other window. This change | |
444 | has no effect when enable-recursive-minibuffers is nil (the default). | |
3c241617 | 445 | +++ |
4f75e082 JL |
446 | *** Isearch started in the minibuffer searches in the minibuffer history. |
447 | Reverse Isearch commands (C-r, C-M-r) search in previous minibuffer | |
448 | history elements, and forward Isearch commands (C-s, C-M-s) search in | |
297b8ccd JL |
449 | next history elements. When the reverse search reaches the first history |
450 | element, it wraps to the last history element, and the forward search | |
451 | wraps to the first history element. When the search is terminated, the | |
452 | history element containing the search string becomes the current. | |
453 | ||
6c897494 CY |
454 | *** The variable read-file-name-completion-ignore-case overrides |
455 | completion-ignore-case for file name completion. | |
456 | ||
457 | *** The variable read-buffer-completion-ignore-case overrides | |
458 | completion-ignore-case for buffer name completion. | |
3307af6c CY |
459 | --- |
460 | *** `completion-styles' can be customized to choose your favorite | |
461 | completion style. | |
462 | --- | |
463 | *** The default completion styles include a form of partial-completion. | |
464 | --- | |
465 | *** The new command `minibuffer-force-complete' chooses one of the | |
466 | possible completions, rather than stopping at the common prefix. | |
467 | +++ | |
468 | *** If `completion-auto-help' is `lazy', Emacs shows the completions | |
469 | buffer only on the second attempt to complete. This was already | |
470 | supported in `partial-completion-mode'. | |
6c897494 | 471 | |
505d8756 | 472 | ** Face changes |
6c8ad8f7 | 473 | +++ |
b350bdf2 CY |
474 | *** S-down-mouse-1 now pops up a menu for changing the font and text |
475 | size of the default face in the current buffer. The face is changed | |
133c4dc5 | 476 | via face remapping (see Lisp changes, below). |
5f9e21a9 CY |
477 | +++ |
478 | *** New commands to change the default face size in the current buffer. | |
479 | To increase it, type `C-x C-+' or `C-x C-='. To decrease it, type | |
480 | `C-x C--'. To restore the default (global) face size, type `C-x C-0'. | |
d59f7c45 CY |
481 | These work via Text Scale mode, a new minor mode. |
482 | ||
483 | The final key in the above commands may be repeated without the | |
484 | leading `C-x', e.g. `C-x C-= C-= C-=' increases the face height by | |
485 | three steps. Each step scales the height of the default face by the | |
486 | value of the variable `text-scale-mode-step'. | |
487 | ||
488 | *** The command `buffer-face-mode' prompts for a face name, and remaps | |
489 | the default face in the current buffer to that specified face. The | |
490 | command `variable-pitch-mode' turns on Buffer Face mode for the | |
491 | `variable-pitch' face. | |
f20186fd | 492 | |
09e18d03 | 493 | ** Primary selection changes |
ac40fadb | 494 | +++ |
09e18d03 CY |
495 | *** If `select-active-regions' is t, setting the mark automatically |
496 | makes the new region into the primary selection (for interaction with | |
497 | other window applications). If you enable this, you might want to | |
498 | bind `mouse-yank-primary' to Mouse-2. | |
ac40fadb | 499 | +++ |
b350bdf2 CY |
500 | *** You can disable kill ring commands from accessing the primary |
501 | selection by setting `x-select-enable-primary' to nil. | |
2e282009 | 502 | |
e6fda206 | 503 | --- |
697f6b43 CY |
504 | ** Continuation lines can now be wrapped at word boundaries |
505 | (word-wrapping). This is controlled by the new per-buffer variable | |
506 | `word-wrap'. Word wrapping does not take place if continuation lines | |
507 | are not shown, e.g. if truncate-lines is non-nil. The most convenient | |
508 | way to enable word-wrapping is using the new minor mode Visual Line | |
509 | mode; in addition to setting `word-wrap' to t, this rebinds some | |
510 | editing commands to work on screen lines rather than text lines. See | |
511 | New Modes and Packages, below. | |
85b1de32 | 512 | |
463c6766 | 513 | ** Window management changes |
b684436f | 514 | +++ |
463c6766 CY |
515 | *** truncate-partial-width-windows now accepts integer values, which |
516 | specify a minimum window width for partial-width windows, below which | |
7d09b7a6 | 517 | lines are truncated. The default has been changed to 50. |
463c6766 CY |
518 | |
519 | *** The new command balance-windows-area balances windows both | |
520 | vertically and horizontally. | |
e6fda206 | 521 | --- |
8f5cee6a MR |
522 | *** pop-to-buffer now always sets input focus when the popped-to window |
523 | is on a different frame. | |
524 | ||
09e18d03 | 525 | ** Miscellaneous changes: |
97431b7f | 526 | +++ |
09e18d03 CY |
527 | *** C-l is bound to the new command recenter-top-bottom, rather than recenter. |
528 | This moves the current line to window center, top and bottom on | |
529 | successive invokations. | |
5c6e52b0 | 530 | +++ |
09e18d03 | 531 | *** scroll-preserve-screen-position also preserves the column position. |
3a8de8dc | 532 | +++ |
09e18d03 CY |
533 | *** If `yank-pop-change-selection' is t, rotating the kill ring also |
534 | updates the selection or clipboard to the current yank, just as M-w | |
535 | would do so with the text it copies to the kill ring. | |
09e18d03 CY |
536 | +++ |
537 | *** C-M-% now shows replacement as it would look in the buffer, with | |
538 | `\N' and `\&' substituted according to the match. Old behavior can be | |
539 | restored by customizing `query-replace-show-replacement'. | |
540 | ||
541 | *** The command shell prompts for the default directory, when it is | |
542 | called with a prefix and the default directory is a remote file name. | |
543 | This is because some file name handlers (like ange-ftp) are not able to | |
544 | run processes remotely. | |
dd4c0a92 | 545 | +++ |
09e18d03 CY |
546 | *** The new command kill-matching-buffers kills buffers whose name |
547 | matches a regexp. | |
548 | ||
b350bdf2 CY |
549 | *** The new commands `pp-macroexpand-expression' and |
550 | `pp-macroexpand-last-sexp' pretty-print macro expansions. | |
f4bd91be | 551 | +++ |
018a960d EZ |
552 | *** The new command `set-file-modes' allows to set file's mode bits. |
553 | The mode bits can be specified in symbolic notation, like with GNU | |
e6979067 DN |
554 | Coreutils, in addition to an octal number. `chmod' is a new |
555 | convenience alias for this function. | |
d334fa1e | 556 | |
d2c52e26 EZ |
557 | *** `next-error-recenter' specifies how next-error should recenter the |
558 | visited source file. Its value can be a number (for example, 0 for | |
559 | top line, -1 for bottom line), or nil for no recentering. | |
c594dbfa CY |
560 | +++ |
561 | *** When typing in a password in the echo area, C-y yanks the current | |
562 | kill into the password. | |
53374291 DN |
563 | |
564 | *** `mkdir' is a new convenience alias for `make-directory'. | |

617 | ** nXML Mode |
618 | This is a new mode for editing XML documents. It allows a schema to | |
619 | be associated with the XML document being edited, using Relax NG as | |
620 | the schema language. The schema is used to provide two key features: | |
621 | ||
622 | *** Continuous validation. nXML validates as you type, highlighting | |
623 | any invalid parts of your document. | |
624 | ||
625 | *** Completion. nXML can assist you in entering an element name, | |

1107 | ** Case is now considered significant in completion on MS-Windows. |
1108 | The default value of `completion-ignore-case' is now nil on | |
1109 | MS-Windows, the same as it is for other operating systems. The | |
1110 | variable doesn't apply to reading a file name -- in that case Emacs | |
1111 | heeds `read-file-name-completion-ignore-case' instead. | |

1114 | ** IPv6 is supported on MS-Windows. | |
1115 | Emacs now supports IPv6 on Windows XP and later, and earlier versions | |
2660a9da | 1116 | of Windows with third party IPv6 stacks installed. In Emacs 22, IPv6 was |
672f99b6 JR |
1117 | supported on other platforms, but not on Windows due to using the winsock |
1118 | 1.1 header file, even though Emacs was linking to the winsock 2 library. | |

1123 | In Emacs 22 only X supported the busy cursor. |

1126 | ** Battery status is available on MS-Windows | |
1127 | Emacs can now display the battery status in the mode-line when enabled with | |
1128 | display-battery-mode or from the Options menu. More verbose battery | |
1129 | information is also available with the command `battery'. In Emacs 22 | |
1130 | battery status was supported only on GNU/Linux and Mac. | |
6e344060 | 1131 | |

1132 | ** More keys available on MS-Windows. |
1133 | Keys normally associated with IMEs, and some exotic keys not normally found | |
1134 | on standard keyboards have been given names so they can be bound to functions | |
1135 | inside Emacs. If there are keys on your keyboard that have not been exposed | |
1136 | to Emacs in the past, try C-h k to see if they are available now. | |
1137 | ||
1138 | Emacs can now bind functions to the extra buttons for media player and | |
1139 | browser control present on some keyboards. These buttons are disabled | |
1140 | by default, since enabling them prevents their system-wide use when | |
1141 | Emacs has focus. To enable them, set the variable | |
0caa490b | 1142 | w32-pass-multimedia-buttons to nil. See the doc string of that variable |
3280c5c5 | 1143 | for the list of extra keys that are available. |

1145 | ** BDF fonts no longer supported on MS-Windows. |
1146 | The font backend was completely rewritten for this release. The focus | |
1147 | on Windows has been getting acceptable performance and full unicode | |
1148 | support, including complex script shaping for native Windows fonts. A | |
1149 | rewrite of the BDF font support has not happened due to lack of time | |
1150 | and developers. If demand still exists for such a backend even with | |
1151 | the improved language support for native Windows fonts, future | |
1152 | development in this direction will most likely be based on the | |
1153 | freetype library, giving access to a wider range of font formats. | |
