M-x means - press the `x' key while holding down the Meta key. M-C-x means press the - `x' key while holding down both the Control key and the Meta key. C-M-a - is a synonym for M-C-a. RET, LFD, DEL, ESC, and TAB respectively refer to - pressing the Return, Linefeed (aka Newline), Delete, Escape, and Tab keys - and are equivalent to C-m, C-j, C-?, C-[, and C-i. SPC means press the - Space bar. - - I put any key sequence that is longer than one key (and some single-key - sequences) inside double quotes or on a line by itself. Any real spaces - in such a key sequence should be ignored; only SPC really means press the - space key. - + + C-x means press the `x' key while holding down the Control key. M-x + means press the `x' key while holding down the Meta key. M-C-x means + press the `x' key while holding down both the Control key and the Meta + key. C-M-a is a synonym for M-C-a. RET, LFD, DEL, ESC, and TAB + respectively refer to pressing the Return, Linefeed (aka Newline), + Delete, Escape, and Tab keys and are equivalent to C-m, C-j, C-?, C-[, + and C-i. SPC means press the Space bar. + + Key sequences longer than one key (and some single-key sequences) are + inside double quotes or on lines by themselves. Any real spaces in such + a key sequence should be ignored; only SPC really means press the space + key. + The ASCII code sent by C-x (except for C-?) is the value that would be sent by pressing just `x' minus 96 (or 64 for uppercase `X') and will be from 0 to 31. The ASCII code sent by M-x is the sum of 128 and the ASCII code that would be sent by pressing just the `x' key. Essentially, the Control key turns off bits 5 and 6 and the Meta key turns on bit 7. - - For further information, see `Characters' and `Keys' in the online manual. - - NOTE: C-?

It is a misnomer to call C-? a "control" key, since 127 has both bits 5 and 6 turned ON. Also, on very few keyboards does Control-? generate ASCII code 127. - + 2: What does "M-x command" mean? - + "M-x command" means type M-x, then type the name of the command, then type RET. - + M-x (by default) invokes the command `execute-extended-command'. This command allows you to run any Emacs command if you can remember the command's name. If you can't remember the command's name, you can type - TAB and SPC for completion, and "?" for a list of possibilities. An Emacs - "command" is any "interactive" Emacs function. - + TAB and SPC for completion, "?" for a list of possibilities, and M-p and + M-n to see previous commands entered. An Emacs "command" is any + "interactive" Emacs function. + NOTE: Your system administrator may have bound other key sequences to invoke execute-extended-command.

Status of Emacs 23: Where does the name "Emacs" come from? - + Emacs originally was an acronym for Editor MACroS. RMS says he "picked the name `Emacs' because `E' was not in use as an abbreviation on ITS at - the time.". The first Emacs was a set of macros written in 1976 at MIT by - RMS for the editor TECO (Text Editor and COrrector (originally Tape Editor - and COrrector)) under ITS on a PDP-10.

Fixes from 18.57 include better - mail address parsing, an X visual bell speedup, a call-process - enhancement, a regexp matching change, the ability to apply a numeric - argument to a self-inserting digit, getting X resource values from the - RESOURCE_MANAGER property, more reliable shell mode job control, and a - change to copy-keymap.

Its is GNU Emacs 19. I still can't say exactly when ! - public release is going to be, but we are about to start testing at a ! - number of sites. ! - ! - GNU Emacs 19 will support a broad spectrum of machines, like Emacs ! - 18.

See question 121. - - Work has begun on features for Emacs 20. - -26: What is different about GNU Emacs 19? - - From the January 1992 GNU's Bulletin: - - Version 19 will enter beta test late this year. Among its new features - are: before and after change hooks, source-level debugging of Emacs Lisp - programs, X selection processing (including clipboard selections), - scrollbars, support for European character sets, floating point numbers, - per-buffer mouse commands, X resource manager interfacing, - mouse-tracking, Lisp-level binding of function keys, multiple X windows - (`screens' to Emacs), a new input system, and buffer allocation, which - uses a new mechanism capable of returning storage to the system when a - buffer is killed. - - The input stream is now a sequence of Lisp objects, instead of a - sequence of characters. This allows a reasonable representation for - mouse clicks, function keys, menu selections, etc. - - Thanks go to Alan Carroll and the people who worked on Epoch for - generating initial feedback to a multi-windowed Emacs, and to Eric - Raymond for help in polishing the Emacs 19 Lisp libraries. - - The June 1991 GNU's bulletin had this to say about future plans for Emacs: - - Features being considered for later releases of Emacs include: - associating property lists with regions of text in a buffer; multiple - fonts, color, and pixmaps defined by those properties; different - visibility conditions for the regions, and for various windows showing - one buffer; hooks to be run if point or mouse moves outside a certain - range; incrementally saving undo history in a file; static menu bars; - and better pop-up menus. - - Mention of this feature disappeared in the January 1992 GNU's bulletin: - - Emacs 19 supports two styles of multiple windows, one with a separate - screen for the minibuffer, and another with a minibuffer attached to - each screen. - - Mention of these two proposed features disappeared in the January 1991 - GNU's bulletin: - - * Incremental syntax analysis for various programming languages (Leif). - * A more sophisticated emacsclient/server model, which would provide - network transparent Emacs widget functionality. - -27: What variants of GNU Emacs exist? - - * Nemacs (Nihongo Emacs), which can handle Japanese text, is derived from - GNU Emacs 18.55.

(This assumes the value of - search-quote-char is 17 (ie., C-q).) Searching for ALL unprintable - characters is best done with a "regexp" search. The easiest regexp to use - for the unprintable chars is the complement of the regexp for the + example, `\237', you can type "C-s C-q 2 3 7". (This assumes the value + of search-quote-char is 17 (i.e., C-q).) Searching for ALL unprintable + characters is best done with a "regexp" search. The easiest regexp to + use for the unprintable chars is the complement of the regexp for the printable chars. - + Regexp for the printable chars: [\t\n\r\f -~] - + Regexp for the unprintable chars: [^\t\n\r\f -~] - + To type some of these special characters in an interactive argument to isearch-forward-regexp or re-search-forward, you need to use C-q. (`\t', `\n', `\r', and `\f' stand respectively for TAB, LFD, RET, and C-l.) So, to search for unprintable characters using re-search-forward: - + M-x re-search-forward RET [^ TAB C-q LFD C-q RET C-q C-l SPC -~] RET - + Using isearch-forward-regexp: - + M-C-s [^ TAB RET C-q RET C-q C-l SPC -~] - - To delete all unprintable characters, simply use a replace-regexp: - + + To delete all unprintable characters, simply use replace-regexp: + M-x replace-regexp RET [^ TAB C-q LFD C-q RET C-q C-l SPC -~] RET RET - - Replacing is similar to the above. {I need to write the text for this - part of the answer!} - - Notes: - - * With isearch, you can type RET to get a quoted LFD (not a quoted RET). - - * You don't need to quote TAB with either isearch or typing something in - the minibuffer. - - Here are the Emacs Lisp forms of the above regexps: - - ;; regexp matching all printable characters: - "[\t\n\r\f -~]" - - ;; regexp matching all unprintable characters: - "[^\t\n\r\f -~]" - -35: How can I highlight a region of text in Emacs? - - There are ways to get highlighting (reverse video, inverse video) in GNU - Emacs 18.59, but either they require patching the C code of Emacs and - rebuilding, or they are slow and the highlighting disappears if you scroll - or redraw the screen and it can not follow the point. Howard Gayle's - patches for 8-bit output appear to allow highlighting (see question - ^8-bit-output). Another patch for highlighting is by Kenichi Handa - <handa@etl.go.jp>. There is a patch for use with X by Andy Norman - <ange@hplb.hpl.hp.com> (and modified for 18.57 by Matthieu Herrb - <matthieu@laas.fr>), which is available for FTP: - - /laas.laas.fr:pub/emacs/patch-X11-18.55 - /laas.laas.fr:pub/emacs/patch-X11-18.57 - - You can highlight regions in a variety of ways in Epoch and Lucid Emacs. - GNU Emacs 19 may not be able to just temporarily highlight a region. - - Similar comments apply to displaying text in different fonts, except that - it is even harder. - -36: How do I control Emacs's case-sensitivity when searching/replacing? - + + Replacing is similar to the above. To replace all unprintable characters + with a colon, use: + + M-x replace-regexp RET [^ TAB C-q LFD C-q RET C-q C-l SPC -~] RET : RET + + NOTE: * You don't need to quote TAB with either isearch or typing + something in the minibuffer. + +33: How can I highlight a region of text in Emacs? + + If you are using a windowing system such as X, you can cause the region + to be highlighted when the mark is active by including + + (transient-mark-mode t) + + in your .emacs. There are also the following packages for content- based + highlighting: + + hilit19.el + font-lock.el + +34: How do I control Emacs's case-sensitivity when searching/replacing? + For searching, the value of the variable case-fold-search determines whether they are case sensitive: - + (setq case-fold-search nil) ; make searches case sensitive (setq case-fold-search t) ; make searches case insensitive - + Similarly, for replacing the variable case-replace determines whether replacements preserve case. - + To change the case sensitivity just for one major mode, use the major mode's hook. For example: - - (setq XXX-mode-hook + + (add-hook 'XXX-mode-hook (function - (lambda () - (setq case-fold-search nil)))) - -37: How do I make Emacs wrap words for me? - - M-x auto-fill-mode. The default maximum line width is 74, determined by - the variable fill-column. To find how to turn this on automatically see - question 32. - -38: Where can I get a better spelling checker for Emacs? - - Use Ispell.

In the TeX distribution, there are several - different programs named `detex', all with incompatible options, and a - very old pair of programs named `detex' and `delatex', which should - probably be avoided. The most useful one for Ispell is `detex' by Daniel - Trinkle.

You - need to put the X11R4 server into X11R3 bug compatibility mode for Emacs's - Xmenu code to work. You can do this with the command `xset bc'. - -79: Why doesn't display-time show the load average in the mode line - anymore? - - In GNU Emacs 18.56, a change was made in the display-time code. - Formerly, in version 18.55, Emacs used a program named `loadst' to - notify Emacs of the change in time every minute. loadst also sent Emacs - the system load average if it was installed with sufficient privilege to - get that information (or was on a system where no such privilege was - needed). Emacs then displayed this information in the mode line. - - In version 18.56, this code was changed to use a program named `wakeup'. - wakeup doesn't send Emacs any information, it's only purpose is to send - Emacs *something* every minute, thus invoking the filter function in - Emacs once a minute. The filter function in Emacs does all the work of - finding the time, date, and load average. However, getting the load - average requires the privilege to read kernel memory on most systems. - Since giving Emacs this privilege would destroy any security a system - might have, for almost everyone this is not an option. In addition, - Emacs does not have the code built into it to get this information on - the systems which have special system calls for this purpose, even - though loadst had code for this. - - The solution I use is to get the files lisp/display-time.el and - etc/loadst.c from version 18.55 and use those with 18.58. (I have heard - a rumor that loadst disappeared because of the legal action Unipress - threatened against IBM.) - - WARNING: Do not install Emacs setgid kmem unless you wish to destroy - any security your system might have!!!!!!!!!! - - If you are using Emacs 18.55 or earlier, or already using the solution I - describe above, read further: - - The most likely cause of the problem is that `loadst' can't read the - special file /dev/kmem. To properly install loadst, it should be either - setuid to the owner of /dev/kmem, or is should be setgid to the group to - which /dev/kmem belongs. In either case, /dev/kmem should be readable by - its owner or its group, respectively. Assuming the existence of a group - named `kmem', here is an example of how to do this: - - chgrp kmem /dev/kmem - chmod g+r /dev/kmem - chgrp kmem /usr/local/emacs/etc/loadst - chmod g+s /usr/local/emacs/etc/loadst - - Another possibility is that your version of Unix doesn't have the load - average data available in /dev/kmem. Your version of Unix might have a - special system call to retrieve this information (eg., inq_stats under - UMAX), and loadst might not have been enhanced to cope with this. - -80: Why does ispell sometimes ignore the local dictionary? - - You need to update the version of Ispell to 2.0.02.

Emacs 19 will have amazing mouse and window support. Right - now, there are Epoch which is derived from GNU Emacs 18.58 and Lucid GNU - Emacs which is derived from an early unreleased version of GNU Emacs 19, - both of which have greatly improved mouse and window support. See - questions 120 and 121. - - The HP unofficial GNU Emacs also has nice mouse support. See question - 95. - - There are numerous Emacs Lisp packages that have been written to extend - Emacs 18's mouse handling capabilities. Some of these packages also have - patches to the C code to provide enhanced capabilities. Look up `mouse' - in the Lisp Code Directory (see question 88). - - There is a package called BAM (Born Again Menus) which provides menus for - GNU Emacs via an external C program. It does not provide mouse support in - the Emacs window such as scrollbars, cut-and-paste, etc. - - NOTE: Epoch only works with the X Window System; it works on ordinary - terminals by invoking regular GNU Emacs. Lucid Emacs does not currently - work on ordinary terminals, although there are plans to fix this. - -93: What is the difference between GNU Emacs and Epoch? - - Marc Andreessen <marca@ncsa.uiuc.edu> writes: - - Epoch is GNU Emacs on steroids: an adaptation of GNU Emacs with lots of - additional support for features made possible by the X11 windowing - system. These features include multiple editing windows, arbitrary - colors and fonts (fixed-width and proportional), selectable zones per - buffer with arbitrary display styles (font, color, underline, stipple, - pixmap), an optional separate minibuffer window, improved keyboard and - mouse handling, full 8-bit character set support, and more. - -94: What is the difference between GNU Emacs and Lucid GNU Emacs? - - This information is condensed from the release notice: - - Lucid GNU Emacs is based on an early version of GNU Emacs version 19 - with many enhancements. It currently requires X Windows to run. For - information on where to get Lucid GNU Emacs see 121. X Windows support - is greatly enhanced over GNU Emacs version 18, including support for - multiple X Windows (a.k.a. screens in Emacs), Zmacs/Lispm style region - highlighting, a customizable, Motif-like menubar, more powerful keymap - support (allowing different actions to be associated with Backspace, - Control-h, etc.), flexible text attribute (e.g. font, color) support on - regional and screen-local basis through X resources and/or lisp, and - support for the X11 selection mechanism. Some other features include - run-time computation of the load-path, support for floating point - numbers, native timer support, and sound file support on Sun - SPARCstations. To build Lucid GNU Emacs, an ANSI C compiler (e.g. gcc) - is required. - -95: Where can I get the "unofficial HP GNU Emacs"? - - The unofficial HP GNU Emacs is available via anonymous FTP: - - /ee.utah.edu:HUGE/ (PLEASE FTP DURING NON-WORK HOURS!!!) - - and takes about 35 megabytes of disk space to build. It is useful for - non-HP machines, but some of the added features will only work under - HP-UX. - - You will need to get patches to work with HP-UX 8.0 or on 700 series - machines via e-mail from Darryl Okahata <darrylo@sr.hp.com>. - -96: Where can I get Emacs for my PC running MS-DOS? - - * Demacs - - For 386 or 486 PCs running MS-DOS, there is a version of GNU Emacs - called Demacs. To get Demacs see question 122. - - From the announcement message: - - Demacs is almost a full set of GNU Emacs but does not support some - features: asynchronous process, locking a file, etc. - - Demacs provides following DOS specific features: - - * File type: text or binary file translation. - * "8-bit clean" display mode. - * 8086 software interrupt call by int86 lisp function. - * Machine specific features such as function key support. - * File name completion with drive name. - * Child process (suspend-emacs, call-process). - * Enhanced dired mode which can work without 'ls.exe'. - - To our regret `shell-mode' does not work, but `compile' command works - properly. - - Demacs was developed using an MS-DOS version of gcc called djgpp by - D. J. Delorie <dj@ctron.com> which can compile and run large programs - under MS-DOS, but not under MS Windows. Demacs was derived from Nemacs - rather than straight from GNU Emacs. - - There are a variety of other Emacses for MS-DOS including among them the - following. - - * Freemacs - - Russ Nelson <nelson@sun.soe.clarkson.edu>, the author, describes - Freemacs: - - * Freemacs is free, and it was designed from the start to be - programmable. - * Freemacs is the only IBM-PC editor that tries to be like GNU Emacs. - * Freemacs can only edit files less than 64K in length. - * Freemacs doesn't have undo. - - Carl Witty <cwitty@cs.stanford.edu> reviews Freemacs: - - Better is Freemacs, which follows the tradition of ITS and GNU Emacs - by having an full, turing-complete extension language which is - incompatible with everything else. In fact, it's even closer to ITS - Emacs than GNU Emacs is, because Mint (Freemacs' extension language) - is absolutely illegible without weeks of study, much like TECO. - - To get Freemacs see question 123. - - * MicroEmacs - - MicroEmacs is a descendant of Microemacs {originally by Dave Conroy?}. - It is programmable in a BASIC-like language. Many of the keybindings - are different from GNU Emacs. The author is Daniel Lawrence - - <dan@mdbs.uucp, mdbs!dan@ee.ecn.purdue.edu>. The latest version is 3.12 ! - and it is available via anonymous FTP: - - /midas.mgmt.purdue.edu:dist/uemacs312/ (outside business hours) ! - ! - Version 3.12 includes Windows and Windows NT versions and a DOS ! - protected mode (DMPI) version. ! + except that files larger than one megabyte are split into multiple parts. + If you have trouble transferring large files, you should try here.

It is currently being merged + into XEmacs (formerly "Lucid Emacs"), and the Epoch redisplay, now + being rewritten, is slated to be merged into Emacs when the rewrite is done. + +82: What is the difference between Emacs and XEmacs (formerly "Lucid + Emacs")? + + XEmacs is a modified version of GNU Emacs. + + A comparison between the two versions, written by the XEmacs + maintainers, had been included here. Richard Stallman removed it + from this copy of the FAQ because it was unfair. It was (1) + one-sided, listing only advantages of XEmacs and not advantages of + the principal version of Emacs, (2) biased, involving opinions the + FSF doesn't share, and (3) out of date, listing as advantages of + XEmacs features which in fact both versions have. + +83: Where can I get Emacs for my PC running MS-DOS? + + Recent releases of GNU Emacs 19 should compile right out of the box on + PCs with a 386 or better, running MS-DOS 3.0 or later. You will need the + following: + + Compiler: djgpp version 1,11 maint 4 or later. You can get the latest + version by grabbing everything in the following directory + (using anonymous ftp): + + oak.oakland.edu:pub/msdos/djdpp + + Tar: One DOS version of tar is available via anonymous ftp from + + ftp.urc.tue.nl:pub/unixtools/dos + + However, not all DOS versions of tar work equally well, so you + might have to try others if this one gives you trouble. + + Utilities: chmod, make, mv, sed, rm. + + All of these utilities are available via anonymous ftp from + the site + + ftp.iro.umontreal.ca:pub/Internet/gnuish + + You should grab the files futil4ax.zoo (contains chmod.exe, + mv.exe, and rm.exe), sed106ax.zoo (contains sed.exe), and + gzip07ax.zoo (contains gzip.exe). + + The file etc/MSDOS contains some information on the differences between + the Unix and MS-DOS versions of GNU Emacs. + + If you would prefer not to compile Emacs by yourself, you can get + binaries for Emacs 19.24 via anonymous ftp from the following two sites: + + ftp.demon.co.uk:pub/ibmpc/editors/emacs19.24 + ftp.imada.ou.dk:pub/mirrors/msdos/emacs-19.24 + + You might also be interested in Demacs, which runs under MS-DOS (*not* + Microsoft Windows; see question 84) on 386- and 486-based PCs.

To interactively bind keys for all modes, + type `M-x global-set-key RET KEY CMD RET'; for the current major mode + only, type `M-x local-set-key RET KEY CMD RET' (see the Emacs on-line + documentation for further details). -A `+' in the 78th column means something was inserted on the line. A `-' means -something was deleted and a `!' means some combination of insertions and -deletions occurred. + To bind keys on starting Emacs or on starting any given mode, you can use + the following "trick." First bind the key interactively, then + immediately afterwards type `C-x ESC ESC C-a C-k C-g'. Now, the command + needed to bind the key is in the kill ring and can be yanked into the + .emacs file. If the key binding is global, no changes to the command are + required. For example, -Full instructions for getting the latest FAQ are in question 22. Also see the -`Introduction to news.answers' posting in the `news.answers' newsgroup, or send -e-mail to `mail-server@rtfm.mit.edu' with `help' on a body line, or use FTP, -WAIS, or Prospero to rtfm.mit.edu. + (global-set-key (quote [f1]) (quote help-for-help)) + can be place directly into the .emacs file. If the key binding is local, + the command is used in conjunction with the `add-hook' command. For + example, in tex-mode, a local binding might be + (add-hook 'tex-mode-hook + (function (lambda () + (local-set-key (quote [f1]) (quote help-for-help)))) -Changing Key Bindings and Handling Key Binding Problems + NOTE: * Control characters in key sequence position of the form yanked + from the kill ring are given in their graphic form - i.e. CTRL is + shown as `^', TAB as a set of spaces (usually 8), etc. You may + want to convert these into their vector or string forms. + + * If some prefix key of the character sequence to be bound is + already bound as a complete key, then you must unbind it before + the new binding. For example, if `ESC {' is previously bound: + + (global-unset-key [?\e ?{]) ;; or + (local-unset-key [?\e ?{]) + + * Aside from commands and "lambda lists," a vector or string also + can be bound to a key and thus treated as a macro. For example: + + (global-set-key [f10] [?\C-x?\e?\e?\C-a?\C-k?\C-g]) ;; or + (global-set-key [f10] "\C-x\e\e\C-a\C-k\C-g") + + See `Key Bindings' in the Emacs on-line documentation for further + details. + +105: Why does Emacs say `Key sequence XXX uses invalid prefix characters'? + + Usually one of two things has happened. In one case, the control + character in the key sequence has been misspecified (e.g. `C-f' used + instead of `\C-f' within a Lisp expression). In the other case, a + "prefix key" in the keystroke sequence you were trying to bind was + already bound as a "complete key." Historically, the `ESC [' prefix was + usually the problem, in which case you should evaluate either of these + forms before attempting to bind the key sequence: + + (global-unset-key [?\e ?[]) ;; or + (global-unset-key "\e[") + +106: Why doesn't this [terminal or window-system setup] code work in my + .emacs file, but it works just fine after Emacs starts up? + + During startup, Emacs initializes itself according to a given code/file + order. If some of the code executed in your .emacs file needs to be + postponed until the initial terminal or window-system setup code has been + executed but is not, then you will experience this problem (this + code/file execution order is not enforced after startup). + + To postpone the execution of Emacs Lisp code until after terminal or + window-system setup, treat the code as a "lambda list" and set the value + of either the `term-setup-hook' or `window-setup-hook' variable to this + "lambda function." For example, -125: How do I bind keys (including function keys) to commands? - - 1. Find out what character sequence is generated by the keystroke sequence - you wish to bind to a command. See question 129 for how to do this. - Keep in mind that the character sequences generated by a keystroke - sequence varies from one terminal to another. You may also get - different results depending on what type of machine you are running on - (see question 128). For example, these keystrokes may generate these - character sequences: - - F1 ---> ESC [ 2 2 4 z - Shift-R10 ---> ESC O t - L7 ---> ESC [ 3 1 ~ - Remove ---> C-@ - - 2. Figure out what the Emacs Lisp syntax is for this character sequence. - Inside an Emacs Lisp string, RET, LFD, DEL, ESC, SPC, and TAB are - specified with `\r', `\n', `\C-?', `\e', ` ', and `\t'. C-x is - specified by `\C-x'. M-x is specified the same was as "ESC x". - (Control characters may also be specified as themselves, but I don't - recommend it.) An Emacs Lisp string begins and ends with the double - quote character, `"'. Here are some examples: - - ESC [ D ---> "\e[D" - ESC [ 2 2 7 z ---> "\e[227z" - ESC [ 1 8 ~ ---> "\e[18~" - C-M-r ---> "\e\C-r" - - 3. If some prefix of the character sequence is already bound, you must - unbind it by binding it to `nil'. For example: - - (global-set-key "\e[" nil) - - 4. Pick a command to bind your key sequence to. A command can be a - "symbol" with a function definition, or a "lambda list", or a string - (which is treated as a macro). For example: - - (global-set-key "\e[D" 'backward-char) - (global-set-key "\e[227~" "\exgoto-line\r") ; macro - - See `Key Bindings' and `Rebinding' in the online manual. - - In Emacs 19 (including Lucid Emacs), you can bind function key F24 like - this: - - (global-set-key 'f24 'some-command) - -126: Why does Emacs say `Key sequence XXX uses invalid prefix characters'? - - A prefix of the character sequence you were trying to bind was already - bound. Usually, the sequence is "ESC [", in which case you should - evaluate this form first: - - (define-key esc-map "[" nil) - - NOTE: By default, "ESC [" is bound to backward-paragraph, and if you do - this you will lose this key binding. For most people, this is not a - problem. - - See question 125. - -127: Why doesn't this [terminal or window-system setup] code work in my - .emacs file, but it works just fine after Emacs starts up? - - This is because you're trying to do something in your .emacs file that - needs to be postponed until after the terminal/window-system setup code - is loaded. This is a result of the order in which things are done - during the startup of Emacs. For more details see question 135. - - In order to postpone the execution of Emacs Lisp code until after the - terminal/window-system setup, set the value of the variable - term-setup-hook or window-setup-hook to be a function which does what - you want. - - See etc/OPTIONS for a complete explanation of what Emacs does every time - it is started. - - Here is a simple example of how to set term-setup-hook: - (setq term-setup-hook - (function - (lambda () - (cond ((string-match "\\`vt220" (or (getenv "TERM") "")) - ;; Make vt220's "Do" key behave like M-x: - (define-key CSI-map "29~" 'execute-extended-command)) - )))) - -128: How do I use function keys under X Windows? - - This depends on whether you are running Emacs inside a terminal emulator - window, or whether you are allowing Emacs to create its own X window. - You can tell which you are doing by noticing whether Emacs creates a new - window when you start it. - - If you are running Emacs inside a terminal emulator window, then it - behaves exactly as it does on any other tty. In this case, for function - keys to be useful, they must generate character sequences that are sent - to the programs running inside the window as input. The `xterm' program - has two different sets of character sequences that it generates when - function keys are pressed, depending on the sunFunctionKeys X resource - and the -sf and +sf command line options. (To find out what these key - sequences are, see question 129.) In addition, with xterm, - you can override what key sequence a specific function key (or any other - key) will generate with the `translations' resource. This, for example: - - XTerm.VT100.Translations: #override \ - <KeyPress>F1: string(0x1b) string("[xyzzy") - - makes the function key F1 generate the character sequence "ESC [xyzzy". - - On the other hand, if Emacs is managing its own X window, the following - description applies. Emacs receives `KeyPress' events from the X server - when a key is pressed while the keyboard focus is in its window. The - KeyPress event contains an X "keysym" code, which is simply an arbitrary - number corresponding to the name of the keysym, and information on which - "modifiers" such as `control' and `shift' are active. For example, the - `Tab' keysym is 0xff09. (Generally, a key on the keyboard will generate a - keysym whose name is the same as the label on the key, ie. the `Tab' key - will normally generate the `Tab' keysym. This can be changed with the - xmodmap program.) Emacs recognizes all the keysyms that correspond to - standard ASCII characters and internally uses the ASCII character instead. - - (WARNING: I am about to describe a gross, disgusting hack to you, have - your barf bag ready.) - - When Emacs receives the X keysym of one of the arrow keys, it behaves - the same as if it had received a letter key with the control modifier - down as follows (this is hard-coded): - - Up becomes C-p - Down becomes C-n - Right becomes C-f - Left becomes C-b - - The way Emacs treats other keysyms depends on what kind of machine it was - compiled on. The type of the display machine is irrelevant! Function - keys are mapped internally to escape sequences, while other keys are - completely ignored. - - 1. If compiled on a Sun, Emacs recognizes these X keysyms that - are normally on a Sun keyboard: - - F1 through F9 - L1 through L10 (same as F11 through F20) - R1 through R15 (same as F21 through F35) - (The keys labelled R8, R10, R12, and R14 usually are mapped to the - X keysyms Up, Left, Right, and Down.) - Break (the `Alternate' key is given this keysym) - - These keys work like Sun function keys. When Emacs receives the - keysym, it will internally use character sequences that look like "ESC - [ ### z", where ### is replaced by a number. The character sequences - are identical to those generated by Sun's keyboard under SunView. Any - function key not listed above generates "ESC [ - 1 z". - - In order to use these key sequences, they should be bound to commands - using the standard key binding methods, just as if Emacs were running - on a regular terminal. - - WARNING: F11 and L1 are the same keysym in X, as are F12 and L2, etc. - {Yes, this is stupid. Complain to the X consortium.} - - 2. If not compiled on a Sun, the function keys will appear to Emacs in a - way remarkably similar to the keys of a DEC LK201 keyboard (used on - some VT series terminals). These X keysyms will be recognized: - - F1 through F20 - Help (treated same as F15) - Menu (treated same as F16, is the LK201 `Do' key) - Find - Insert (LK201 `Insert Here' key) - Select - Prior (LK201 `Prev Screen' key *** ONLY IN 18.58 AND LATER ***) - Next (LK201 `Next Screen' key *** ONLY IN 18.58 AND LATER ***) - - And finally, the LK201 key labelled `Remove' (or `Delete') is often - mapped to the Delete keysym which generates the DEL character (C-?) - instead of the key sequence given by the LK201 `Remove' key. It may - also be mapped to some other keysym, such as `_Remove', in which case - you can't use it from within Emacs at all. - - Each function key will be internally converted to a character sequence - that looks like "ESC [ ## ~", where ## is replaced by a number. The - character sequences are identical to those generated by a LK201 - keyboard. Any function key not listed above generates "ESC [ - 1 ~". - - For the complete list of the numbers which are generated by the function - keys, look in the file src/x11term.c at the definitions of the function - stringFuncVal. - - If you are running Emacs on a Sun machine, even if your X display is - running on a non-Sun machine (eg., an X terminal), you get the setup - described above for Suns. The determining factor is what type of - machine Emacs is running (was compiled) on, not what type of machine - your X display is on. - - If you have function keys not listed above on your keyboard, you can use - `xmodmap' to change their keysym assignments to get keys that Emacs will - recognize, but that may screw up other programs. - - X resources are not used by Emacs to affect the key sequences generated. - In particular, there are no X key "translations" for Emacs. - - If you have function keys not listed above and you don't want to use - xmodmap to change their names, you might want to make a modification to - your Emacs. Johan Vromans <jv@mh.nl> has made available a patch for Emacs - that adds the x-rebind-key function of Epoch to Emacs 18.58. This allows - another layer of key rebinding before Emacs even sees the keys, and in - this layer you can rebind all of the keys and modifier combinations as - well. - - Anonymous FTP: - /ftp.eu.net:gnu/emacs/FP-Xfun.Z - /ftp.urc.tue.nl:pub/tex/emacs/FP-Xfun - - Johan Vromans explains what this buys for you: - - After implementing this, all keyboard keys can be configured to send - user definable sequences, eg., - - (x-rebind-key "KP_F1" 0 "\033OP") - - This will have the keypad key PF1 send the sequence "ESC O P", just like - an ordinary VT series terminal. - -129: How do I tell what characters my function or arrow keys emit? - - Use this function by Randal L.

During the process of - starting up, Emacs will load a terminal-specific initialization file for - your terminal type (as determined by the environment variable TERM), if - one exists. This file has the responsibility for enabling the arrow keys. - - There are several things that can go wrong: - - 1. There is no initialization file for your terminal. - - You can determine this by looking in the lisp/term directory. If your - terminal type (as determined by the TERM environment variable) is - xxx-yy-z, then the first of these files in the lisp/term directory will - be loaded as the terminal-specific initialization file: xxx-yy-z.el, - xxx-yy.el, or xxx.el. - - There are two major cases of this problem: - - * Your terminal type is very similar to one that has an init file. - - In this case, there are several techniques suggested by Colin Jensen - <cjensen@ampex.com>, Ben Liblit <Liblit@cs.psu.edu>, and Marc - Auslander <marc@watson.ibm.com>: - - A. Add a symbolic link in lisp/term for your terminal type that - points to the similar type. For example, you could make VT102 - terminals work with this command: - - ln -s vt100.el vt102.el - - This fixes things for everyone on the system who uses the terminal - type. - - B. If you can't do the solution in part A, you can add code to your - term-setup-hook that loads the correct file like this: - - (setq term-setup-hook - (function - (lambda () - (cond ((equal "vt102" (or (getenv "TERM") "")) - (load (concat term-file-prefix "vt100"))) - (;; Code for other terminal types goes here ... - ))))) - - C. If you use `tset' to set your TERM environment variable when you - login, you can use the `-m' switch to tell tset to use a terminal - type known by Emacs instead of another similar one. For example, - specifying this: - - tset ... -m 'dec-vt220:vt220' ... - - will make tset say you are on a `vt220' instead of a `dec-vt220'. - - D. Interactively, you can type "M-x load-library RET term/vt100" to - load the terminal-specific initialization files for VT100 - terminals. - - * Your terminal type is not similar to one that has an init file. - - One can be made for your terminal, or you can just add code to your - own .emacs to handle this problem for yourself. For example, if your - terminal's arrow keys send these character sequences: - - Up: ESC [ A - Down: ESC [ B - Right: ESC [ C - Left: ESC [ D - - then you can bind these keys to the appropriate commands with code in - your .emacs like this: - - (setq term-setup-hook - (function - (lambda () - (cond ((string-match "\\`xyzzy" (or (getenv "TERM") "")) - ;; First, must unmap the binding for left bracket - (or (keymapp (lookup-key global-map "\e\[")) - (define-key global-map "\e\[" nil)) - ;; Enable terminal type xyzzy's arrow keys: - (define-key global-map "\e\[A" 'previous-line) - (define-key global-map "\e\[B" 'next-line) - (define-key global-map "\e\[C" 'forward-char) - (define-key global-map "\e\[D" 'backward-char)) - ((string-match "\\`abcde" (or (getenv "TERM") "")) - ;; Do something different for terminal type abcde - ;; ..... - ))))) - - NOTE: You may have to restart Emacs to get changes to take effect. - - NOTE: Your arrow keys may send sequences beginning with "ESC O" when - Emacs is running, even if they send sequences beginning with "ESC [" at - all other times. This is because Emacs uses any command there may be - in your terminal's termcap entry for putting the terminal into - "Application Keypad Mode". Just map these sequences the same way as - above. - - The next two cases are problems even if there is a initialization file for - your terminal type. - - 2. The initialization file for your terminal doesn't bind arrow keys. - - If your terminal type is `xterm', you will have to bind the arrow keys - as in part 1 above, since the xterm.el file doesn't do anything useful. - There may be other terminal types with the same problem. - - 3. Your terminal's arrow keys send individual control characters. - - For example, the arrow keys on an ADM-3 send C-h, C-j, C-k, and C-l. - - There is not much Emacs can do in this situation, since all the control - characters except for C-^ and C-\ are already used as Emacs commands. - It may be possible to convince the terminal to send something else when - you press the arrow keys; it is worth investigating. - - You have to make the hard choices of how to rebind keys to commands to - make things work the way you want. Another alternative is to start - learning the standard Emacs keybindings for moving point around: C-b, - C-f, C-p, and C-n. Personally, I no longer use the arrow keys when - editing because I have switched keyboards so many times. - - 4. Your terminal's arrow keys send sequences beginning with "ESC [". - - Due to an extremely poor design decision (ie., these sequences are ANSI - standard), none of the the terminal-specific initialization files that - are distributed with Emacs will bind these character sequences to the - appropriate commands by default. (This also applies to any other - function keys which generate character sequences starting with "ESC - [".) This is because it was deemed far more important to preserve the - binding of M-[ to the backward-paragraph command. It appears that this - will change in Emacs 19. - - Some of the terminal-specific initialization files that come with Emacs - provide a command enable-arrow-keys that will fix this problem.

After arranging for this Lisp to be - evaluated by Emacs, you can evaluate `(swap-keys ?A ?B)' to swap A and B. - - (defun swap-keys (key1 key2) - "Swap keys KEY1 and KEY2 using map-key." - (map-key key1 key2) - (map-key key2 key1)) - - (defun map-key (from to) - "Make key FROM behave as though key TO was typed instead." - (setq keyboard-translate-table - (concat keyboard-translate-table - (let* ((i (length keyboard-translate-table)) - (j from) - (k i) - (str (make-string (max 0 (- j (1- i))) ?X))) - (while (<= k j) - (aset str (- k i) k) - (setq k (1+ k))) - str))) - (aset keyboard-translate-table from to) - (let ((i (1- (length keyboard-translate-table)))) - (while (and (>= i 0) (eq (aref keyboard-translate-table i) i)) - (setq i (1- i))) - (setq keyboard-translate-table - (if (eq i -1) - nil - (substring keyboard-translate-table 0 (1+ i)))))) - - NOTE: You must evaluate the definition of these functions before calling - them! For example, list the function definitions before their use in your - .emacs file. - - NOTE: These functions take two numbers as arguments. The example above, - `(swap-keys ?A ?B)' is actually `(swap-keys 65 66)', because `?A' is - merely notation for 65, the ASCII value of `A'. - - NOTE: These functions only work for single characters. You cannot swap - two multi-character sequences. - -137: How do I produce C-XXX with my keyboard? - - For C-@ and C-^, often you can just type Control-2 and Control-6. For - C-_, you may have to hold down the shift key, typing Control-Shift-Hyphen. - C-@ can often be generated by typing Control-Space. C-@ is often called - the NUL character, and has ASCII value 0. C-_ can often be generated by - typing Control-7 or Control-/. C-? (aka DEL) may be generated by typing - Shift-BackSpace or Control-BackSpace or a key labelled Delete or Del. - - Try Control with all of the digits on your keyboard to see what gets - generated. - -138: What if I don't have a Meta key? - - Instead of typing M-a, you can type "ESC a" instead. In fact, Emacs - converts M-a internally into "ESC a" anyway (depending on the value of - meta-prefix-char). - -139: What if I don't have an Escape key? - - Type C-[ instead. This should send ASCII code 27 just like an Escape - key would. Try also C-;. - -140: How do I type DEL on PC terminal emulators? - - Some IBM PC compatibles do not have a key labeled `Del' or `Delete' {is - this true?}. Those that do generally have it in an inconvenient location. - (Also, in some terminal emulators, the `Del' key does not transmit DEL.) - The result is the standard "BackSpace invoking help" problem (see question - 133). - - The usual solution, suggested by Michael Covington - <mcovingt@aisun1.ai.uga.edu>, is to somehow tell the terminal emulator - program that BackSpace should transmit DEL. Read the program's manual. - Shift-BackSpace or Control-BackSpace may send DEL. The `Del' key may only - send DEL if the NumLock key hasn't been pressed. - -141: Can I make my `Compose Character' key behave like a Meta key? - + +114: How do I "swap" two keys? + + In Emacs 19, you can swap two keys (or key sequences) by using the + `keyboard-translate' function. For example, to turn `C-h' into DEL and + DEL to `C-h', use + + (keyboard-translate ?\C-h ?\C-?) ; translate `C-h' to DEL + (keyboard-translate ?\C-? ?\C-h) ; translate DEL to `C-h'. + + The first key sequence of the pair after the function identifies what is + produced by the keyboard; the second, what is matched for in the keymaps. + + Keyboard translations are not the same as key bindings in keymaps. Emacs + contains numerous keymaps that apply in different situations, but there + is only one set of keyboard translations, and it applies to every + character that Emacs reads from the terminal. Keyboard translations take + place at the lowest level of input processing; the keys that are looked + up in keymaps contain the characters that result from keyboard + translation. + + Also see `Keyboard Translations' in the on-line manual. + +115: How do I produce C-XXX with my keyboard? + + On terminals (but not under X), some common "aliases" are: + + CTRL-2 or CTRL-SPC for C-@ + CTRL-6 for C-^ + CTRL-7 or CTRL-SHIFT-- for C-_ + CTRL-4 for C-\ + CTRL-5 for C-] + CTRL-/ for C-? + + Often other aliases exist; use the `C-h c' command and try `CTRL' with + all of the digits on your keyboard to see what gets generated. You can + also try the `C-h w' command if you know the name of the command. + +116: What if I don't have a Meta key? + + Instead of typing "M-a", you can type "ESC a". In fact, Emacs converts + M-a internally into "ESC a" anyway (depending on the value of + meta-prefix-char). Note that you press "Meta" and "a" together, while + you press "ESC", release it, and then press "a". + +117: What if I don't have an Escape key? + + Type "C-[" instead. This should send ASCII code 27 just like an Escape + key would. "C-3" may also work on some terminal (but not under X). For + many terminals (notably DEC terminals) "F11" generates the "ESC" key. If + not, the following form can be used bind it: + + (define-key function-key-map [f11] [?\e]) ; F11 is the documented ESC + ; replacement on DEC terminals. + +118: Can I make my `Compose Character' key behave like a Meta key? + On a dumb terminal such as a VT220, no. It is rumored that certain VT220 clones could have their Compose key configured this way. If you're using - X, you might be able to do this with the `xmodmap' program (this is - what I do). - -142: How do I bind a combination of modifier key and function key? - - Unless you're using Emacs under emacstool (or xvetool?), have a working - version of x-rebind-key (see question 128), or are using Emacs 19 (Lucid - Emacs), you can't do this with Emacs alone. - - If you are using emacstool, Emacs sees different character sequences for - the combination of a modifier and a function key from what it sees for the - function key alone. See etc/emacstool.1 for more information. Since - Emacs sees different character sequences, you can bind these different - sequences to different commands. - - If you are running Emacs inside a terminal emulator window like xterm, you - can modify its translation tables to make it generate different character - sequences for the combination of a modifier and a function key. For - example, this X resource setting: - - XTerm.VT100.Translations: #override \ - Shift<KeyPress>F1: string(0x1b) string("[xyzzy") - - makes Shift-F1 generate the character sequence "ESC [ xyzzy". You can - bind these character sequences in Emacs as normal. Nick Ruprecht - <ruprecht@informatik.uni-freiburg.de> has written an extensive X - translation mapping for xterm that does this. {Does this have an FTP - site?} - - If you have x-rebind-key, you can have any arbitrary combination of - modifiers with a key replaced by any sequence of "normal" characters. For - example, this makes Shift-Return behave as though you had typed "C-x C-e" - (example from Jerry Graves): - - (x-rebind-key "Return" 'shift "\C-x\C-e") - - In Emacs 19 (Lucid Emacs), you can bind Meta-Left-Arrow like this (example - from Jamie Zawinski): - - (global-set-key '(meta left) 'backward-word) - - With the last two methods, use `xmodmap' and `xev' to discover the keysym - and modifier names. - -143: Why doesn't my Meta key work in an xterm window? - + X, you might be able to do this with the `xmodmap' program. + +119: How do I bind a combination of modifier key and function key? + + With Emacs 19 you can indicate modified function keys in vector format + through multi-prefixing the function key symbol. For example (from the + Emacs on-line documentation): + + (global-set-key [?\C-x right] 'forward-page) + + where "?\C-x" is the Lisp character constant for the character "C-x". + + You can use the modifier keys CTRL, META, HYPER, SUPER, ALT and SHIFT + with function keys. To represent these modifiers, prepend the strings + "C-", "M-", "H-", "s-", "A-" and "S-" to the symbol name. Thus, here is + how to make "Hyper-Meta-RIGHT" move forward a word: + + (global-set-key [H-M-right] 'forward-word) + + NOTE: * Not all modifiers are permitted in all situations. HYPER, SUPER, + and ALT are available only under X (provided there are such + keys). Non-ASCII keys and mouse events (e.g. "C-=" and + "mouse-1") also fall under this category. + + See question 104 for general key binding instructions. + +120: Why doesn't my Meta key work in an xterm window? + Try all of these methods before asking for further help: - + * You may have big problems using `mwm' as your window manager. {Does anyone know a good generic solution to allow the use of the Meta key in Emacs with mwm?} - - * For X11R4: Make sure it really is a Meta key.

If it shows `cs7' instead, use `stty cs8 -istrip' (or `stty pass8') to fix it. - + * If there is an rlogin connection between the xterm and the Emacs, the - `-8' argument may need to be given to rlogin to make it pass all 8 - bits of every character. - + `-8' argument may need to be given to rlogin to make it pass all 8 bits + of every character. + * If the Emacs is running under Ultrix, it is reported that evaluating (set-input-mode t nil) helps. - + * If all else fails, you can make xterm generate "ESC W" when you type M-W, which is the same conversion Emacs would make if it got the M-W anyway. In X11R4, the following resource specification will do this: - + XTerm.VT100.EightBitInput: false - + (This changes the behavior of the insert-eight-bit action.) - + With older xterms, you can specify this behavior with a translation: - + XTerm.VT100.Translations: #override \ Meta<KeyPress>: string(0x1b) insert() - + You might have to replace `Meta' with `Alt'. - -144: Why doesn't my ExtendChar key work as a Meta key under HP-UX 8.0? - + +121: Why doesn't my ExtendChar key work as a Meta key under HP-UX 8.0? + This is a result of an internationalization extension in X11R4 and the fact that HP is now using this extension.

There is - support for displaying 8-bit characters, as well as for entering such - characters from the keyboard. In addition, upcase/lowcase translation - is supported, accented characters are recognized as "letters" (important - when doing 'forward-word', for example), and text with 8-bit characters - can be sorted correctly. - - A Meta-shift key can still be used, provided that you run in an - environment where it is possible to distinguish between a character - entered using the Meta-shift key and one entered directly. The diffs - include patches to make this work under SunView (with emacstool) as - well as under X. If you can't use a Meta-shift key, you have to enter - Meta-commands with the ESC-prefix. - - The most comprehensive patches for 8-bit output are by Howard Gayle - (originally for Emacs 18.55.

Here is an + excerpt from the `European Display' page of the on-line manual: + + Some European languages use accented letters and other special symbols. + The ISO 8859 Latin-1 character set defines character codes for many + European languages in the range 160 to 255. + + Emacs can display those characters according to Latin-1, provided the + terminal or font in use supports them. The `M-x + standard-display-european' command toggles European character display + mode. With a numeric argument, `M-x standard-display-european' enables + European character display if and only if the argument is positive. + + Some operating systems let you specify the language you are using by + setting a locale. Emacs handles one common special case of this: if + your locale name for character types contains the string `8859-1' or + `88591', Emacs automatically enables European character display mode + when it starts up. + +125: How do I input 8-bit characters? + + Again, from the `European Display' page of the on-line manual: + + If you enter non-ASCII ISO Latin-1 characters often, you might find ISO + Accents mode convenient. When this minor mode is enabled, the + characters ``', `'', `"', `^', `/' and `~' modify the following letter + by adding the corresponding diacritical mark to it, if possible. To + enable or disable ISO Accents mode, use the command `M-x + iso-accents-mode'. This command affects only the current buffer. + + To enter one of those six special characters, type the character, + followed by a space. Some of those characters have a corresponding + "dead key" accent character in the ISO Latin-1 character set; to enter + that character, type the corresponding ASCII character twice.

On these systems, movemail must write lock files, or you risk losing mail. You simply must arrange to let movemail write them. - + Other systems use the flock system call to interlock access. On these systems, you should configure movemail to use flock. - -158: How do I recover my mail files after RMAIL munges their format? - - Users who just want to try RMAIL out to see how it works end up trapped - using it because saved mail in their `mbox' file has been converted into - an incompatible format (BABYL) that only RMAIL understands. RMAIL - provides no obvious way to reverse this transformation. Kyle Jones has - aptly named this "the great Emacs Mail Eating Monster". To convert a mail - file back to standard Unix format, there are several methods: - - * Use the rmail-output ("C-o") command within RMAIL on each message in the - file. First use M-x rmail or M-x rmail-input to visit the RMAIL file in - Rmail mode. Type "1 j" to go to the first message. Use the C-o command - to output the message to a Unix format file. Type "n" to go to the next - message. Repeat. - - * If the file contains hundreds of messages, you may not want to repeat - this for all of them. Instead of the above, after getting to the first - message type this (where "mbox" is the file you want to put the messages - in): - - C-x ( C-o mbox RET M-s ^From: RET M-0 C-x ) - - (The rmail-search command ("M-s") is used instead of just "n" because it - is the only command which will cause an error when it reaches the last - message in the file, which is necessary to terminate the keyboard macro. - This will fail if there are messages in the file that don't have a - `From:' header. This assumes rmail-delete-after-output is nil.) - - It is wise to save a copy of the RMAIL file first, in case you make a - mistake. - - * There are software packages available for converting files or even - entire directories of BABYL files to standard Unix format. These are - helpful in this situation, but are intended mainly for people who have - used RMAIL for a long time and are converting to some other mail reader. - Lookup `rmail', `vm', and `babyl' in the Emacs Lisp Archive (see - question 89). - - You may wish to disable RMAIL to avoid accidentally destroying your mbox - file (I have this in my .emacs): - - (put 'rmail 'disabled t) ; avoid mbox destruction - -159: How do I make Emacs automatically start my mail/news reader? - - Example: - + +135: How do I recover my mail files after Rmail munges their format? + + If you have just done rmail-input on a file and you don't want to save it + in Rmail's format (called BABYL), just kill the buffer (with C-x k). + + If you typed M-x rmail and it read some messages out of your inbox and + you want to put them in a Unix mail file, use C-o on each message. + + If you want to convert an existing file from BABYL format to Unix mail + format, use the command M-x unrmail: it will prompt you for the input and + output file names. + +136: How do I make Emacs automatically start my mail/news reader? + + To start Emacs in Gnus: + emacs -f gnus - - Also: - + + in Rmail: + + emacs -f rmail + + A more convenient way to start with Gnus: + alias gnus 'emacs -f gnus' - - It is probably unwise to automatically start your mail or news reader from - your .emacs file.

GNUS and Gnews come separately. rnews will - be replaced by GNUS in Emacs 19. - - rnews works only with a local news spool directory. Both GNUS and Gnews - handle reading news remotely via NNTP in addition to reading from a local - news spool. GNUS supports reading mail stored in MH folders or articles - saved by GNUS. - - Gnews is styled after `rn' and seems to work like RMAIL. GNUS feels more - like VM. People have complained that GNUS uses a lot of CPU time (it - does). Some people have complained that Gnews is slower than GNUS. - - For more information about GNUS, see question 108. - - Gnews was written by Matthew P. Wiener <weemba@libra.wistar.upenn.edu>. - The latest version seems to be 2.0, posted October 3, 1988. Matthew - posted some fixes on October 26, 1988. Gnews does not appear to have been - supported after this date. In particular, it has been reported that Gnews - does not work with Emacs 18.57. There is a newsgroup for Gnews called - gnu.emacs.gnews. - -161: Why does `rnews' say "No News is good news" when there is news? - - rnews doesn't speak NNTP.

(I have forgotten who originally gave me the idea for this.)) - -167: Why is GNUS so slow to start up? - - GNUS does several things that take quadratic time of the number of - newsgroups that are listed in .newsrc. The quick fix for this is to - remove all the newsgroups in which you have no interest from your .newrc - file by using GNUS's C-k command in the `*Newsgroup*' buffer after - displaying all newsgroups with the L command. If you were to directly - edit your .newsrc to remove the newsgroups, GNUS would add them back. - - GNUS uses a quadratic algorithm to check for duplicates when the .newsrc - file is newer than the .newsrc.el file (ie., you edited your .newsrc). - GNUS uses a quadratic algorithm to check for new newsgroups every time it - connects to the news server. {There may be other quadratic algorithms - that I am not aware of.} - - You can speed up GNUS by using the C-k command in the *Newsgroup* buffer - to remove newsgroups from your .newsrc file. - - Of course, GNUS will run faster if you make sure it is byte-compiled. - - Felix Lee wrote some enhancements called `gnus-speedups.el' that fix some - of the problems.
