+
+Term Mode
+---------
+
+ Term uses Term mode, which has two input modes: In line mode, Term
+basically acts like Shell mode. *Note Shell Mode::. In Char mode,
+each character is sent directly to the inferior subshell, except for
+the Term escape character, normally `C-c'.
+
+ To switch between line and char mode, use these commands:
+ findex term-char-mode
+
+`C-c C-k'
+ Switch to line mode. Do nothing if already in line mode.
+
+`C-c C-j'
+ Switch to char mode. Do nothing if already in char mode.
+
+ The following commands are only available in Char mode:
+`C-c C-c'
+ Send a literal <C-c> to the sub-shell.
+
+`C-c C-x'
+ A prefix command to conveniently access the global <C-x> commands.
+ For example, `C-c C-x o' invokes the global binding of `C-x o',
+ which is normally `other-window'.
+

+
+Paging in the terminal emulator
+-------------------------------
+
+ Term mode has a pager feature. When the pager is enabled, term mode
+will pause at the end of each screenful.
+
+`C-c C-q'
+ Toggles the pager feature: Disables the pager if it is enabled,
+ and vice versa. This works in both line and char modes. If the
+ pager enabled, the mode-line contains the word `page'.
+
+ If the pager is enabled, and Term receives more than a screenful of
+output since your last input, Term will enter More break mode. This is
+indicated by `**MORE**' in the mode-line. Type a `Space' to display
+the next screenful of output. Type `?' to see your other options. The
+interface is similar to the Unix `more' program.

+
+Narrowing
+=========
+
+ "Narrowing" means focusing in on some portion of the buffer, making
+the rest temporarily invisible and inaccessible. Cancelling the
+narrowing and making the entire buffer once again visible is called
+"widening". The amount of narrowing in effect in a buffer at any time
+is called the buffer's "restriction".
+
+`C-x n n'
+ Narrow down to between point and mark (`narrow-to-region').
+
+`C-x n w'
+ Widen to make the entire buffer visible again (`widen').
+
+ Narrowing sometimes makes it easier to concentrate on a single
+subroutine or paragraph by eliminating clutter. It can also be used to
+restrict the range of operation of a replace command or repeating
+keyboard macro. The word `Narrow' appears in the mode line whenever
+narrowing is in effect. When you have narrowed to a part of the
+buffer, that part appears to be all there is. You can't see the rest,
+can't move into it (motion commands won't go outside the visible part),
+and can't change it in any way. However, the invisible text is not
+gone; if you save the file, it will be saved.
+
+ The primary narrowing command is `C-x n n' (`narrow-to-region'). It
+sets the current buffer's restrictions so that the text in the current
+region remains visible but all text before the region or after the
+region is invisible. Point and mark do not change.
+
+ Because narrowing can easily confuse users who do not understand it,
+`narrow-to-region' is normally a disabled command. Attempting to use
+this command asks for confirmation and gives you the option of enabling
+it; once you enable the command, confirmation will no longer be
+required. *Note Disabling::.
+
+ To undo narrowing, use `C-x n w' (`widen'). This makes all text in
+the buffer accessible again.
+
+ Use the `C-x =' command to get information on what part of the
+buffer you narrowed down. *Note Position Info::.

+
+Hardcopy Output
+===============
+
+ The XEmacs commands for making hardcopy derive their names from the
+Unix commands `print' and `lpr'.
+
+`M-x print-buffer'
+ Print hardcopy of current buffer using Unix command `print'
+ (`lpr -p'). This command adds page headings containing the file
+ name and page number.
+
+`M-x lpr-buffer'
+ Print hardcopy of current buffer using Unix command `lpr'. This
+ command does not add page headings.
+
+`M-x print-region'
+ Like `print-buffer', but prints only the current region.
+
+`M-x lpr-region'
+ Like `lpr-buffer', but prints only the current region.
+
+ All the hardcopy commands pass extra switches to the `lpr' program
+based on the value of the variable `lpr-switches'. Its value should be
+a list of strings, each string a switch starting with `-'. For
+example, the value could be `("-Pfoo")' to print on printer `foo'.

+
+Recursive Editing Levels
+========================
+
+ A "recursive edit" is a situation in which you are using XEmacs
+commands to perform arbitrary editing while in the middle of another
+XEmacs command. For example, when you type `C-r' inside a
+`query-replace', you enter a recursive edit in which you can change the
+current buffer. When you exit from the recursive edit, you go back to
+the `query-replace'.
+
+ "Exiting" a recursive edit means returning to the unfinished
+command, which continues execution. For example, exiting the recursive
+edit requested by `C-r' in `query-replace' causes query replacing to
+resume. Exiting is done with `C-M-c' (`exit-recursive-edit').
+
+ You can also "abort" a recursive edit. This is like exiting, but
+also quits the unfinished command immediately. Use the command `C-]'
+(`abort-recursive-edit') for this. *Note Quitting::.
+
+ The mode line shows you when you are in a recursive edit by
+displaying square brackets around the parentheses that always surround
+the major and minor mode names. Every window's mode line shows the
+square brackets, since XEmacs as a whole, rather than any particular
+buffer, is in a recursive edit.
+
+ It is possible to be in recursive edits within recursive edits. For
+example, after typing `C-r' in a `query-replace', you might type a
+command that entered the debugger. In such a case, two or more sets of
+square brackets appear in the mode line(s). Exiting the inner
+recursive edit (here with the debugger `c' command) resumes the
+query-replace command where it called the debugger. After the end of
+the query-replace command, you would be able to exit the first
+recursive edit. Aborting exits only one level of recursive edit; it
+returns to the command level of the previous recursive edit. You can
+then abort that one as well.
+
+ The command `M-x top-level' aborts all levels of recursive edits,
+returning immediately to the top level command reader.
+
+ The text you edit inside the recursive edit need not be the same text
+that you were editing at top level. If the command that invokes the
+recursive edit selects a different buffer first, that is the buffer you
+will edit recursively. You can switch buffers within the recursive edit
+in the normal manner (as long as the buffer-switching keys have not been
+rebound). While you could theoretically do the rest of your editing
+inside the recursive edit, including visiting files, this could have
+surprising effects (such as stack overflow) from time to time. It is
+best if you always exit or abort a recursive edit when you no longer
+need it.
+
+ In general, XEmacs tries to avoid using recursive edits. It is
+usually preferable to allow users to switch among the possible editing
+modes in any order they like. With recursive edits, the only way to get
+to another state is to go "back" to the state that the recursive edit
+was invoked from.

+
+Dissociated Press
+=================
+
+ `M-x dissociated-press' is a command for scrambling a file of text
+either word by word or character by character. Starting from a buffer
+of straight English, it produces extremely amusing output. The input
+comes from the current XEmacs buffer. Dissociated Press writes its
+output in a buffer named `*Dissociation*', and redisplays that buffer
+after every couple of lines (approximately) to facilitate reading it.
+
+ `dissociated-press' asks every so often whether to continue
+operating. Answer `n' to stop it. You can also stop at any time by
+typing `C-g'. The dissociation output remains in the `*Dissociation*'
+buffer for you to copy elsewhere if you wish.
+
+ Dissociated Press operates by jumping at random from one point in the
+buffer to another. In order to produce plausible output rather than
+gibberish, it insists on a certain amount of overlap between the end of
+one run of consecutive words or characters and the start of the next.
+That is, if it has just printed out `president' and then decides to
+jump to a different point in the file, it might spot the `ent' in
+`pentagon' and continue from there, producing `presidentagon'. Long
+sample texts produce the best results.
+
+ A positive argument to `M-x dissociated-press' tells it to operate
+character by character, and specifies the number of overlap characters.
+A negative argument tells it to operate word by word and specifies the
+number of overlap words. In this mode, whole words are treated as the
+elements to be permuted, rather than characters. No argument is
+equivalent to an argument of two. For your againformation, the output
+goes only into the buffer `*Dissociation*'. The buffer you start with
+is not changed.
+
+ Dissociated Press produces nearly the same results as a Markov chain
+based on a frequency table constructed from the sample text. It is,
+however, an independent, ignoriginal invention. Dissociated Press
+techniquitously copies several consecutive characters from the sample
+between random choices, whereas a Markov chain would choose randomly for
+each word or character. This makes for more plausible sounding results
+and runs faster.
+
+ It is a mustatement that too much use of Dissociated Press can be a
+developediment to your real work. Sometimes to the point of outragedy.
+And keep dissociwords out of your documentation, if you want it to be
+well userenced and properbose. Have fun. Your buggestions are welcome.

+
+ Besides producing a file of scrambled text with Dissociated Press,
+you can generate random sentences by using CONX.

+
+`M-x conx-load'
+ Load a `conx' database that has been previously saved with `M-x

+
+`M-x conx-region'
+ Absorb the text in the current buffer into the `conx' database.
+

+ Save the current `conx' database to a file for future retrieval.
+
+ Copy text from a buffer using `M-x conx-buffer' or `M-x conx-region'
+and then type `M-x conx'. Output is continuously generated until you
+type <^G>. You can save the `conx' database to a file with `M-x

+database, use `M-x conx-init'.

+File: xemacs.info, Node: Emulation, Next: Customization, Prev: Amusements, Up: Top
+
+Emulation
+=========
+
+ XEmacs can be programmed to emulate (more or less) most other
+editors. Standard facilities can emulate these:
+
+Viper (a vi emulator)
+ In XEmacs, Viper is the preferred emulation of vi within XEmacs.
+ Viper is designed to allow you to take advantage of the best
+ features of XEmacs while still doing your basic editing in a
+ familiar, vi-like fashion. Viper provides various different
+ levels of vi emulation, from a quite complete emulation that
+ allows almost no access to native XEmacs commands, to an "expert"
+ mode that combines the most useful vi commands with the most
+ useful XEmacs commands.
+
+ To start Viper, put the command
+
+ (viper-mode)
+
+ in your init file. *Note Init File::.
+
+ Viper comes with a separate manual that is provided standard with
+ the XEmacs distribution.
+
+EDT (DEC VMS editor)
+ Turn on EDT emulation with `M-x edt-emulation-on'. `M-x
+ edt-emulation-off' restores normal Emacs command bindings.
+
+ Most of the EDT emulation commands are keypad keys, and most
+ standard Emacs key bindings are still available. The EDT
+ emulation rebindings are done in the global keymap, so there is no
+ problem switching buffers or major modes while in EDT emulation.
+
+Gosling Emacs
+ Turn on emulation of Gosling Emacs (aka Unipress Emacs) with `M-x
+ set-gosmacs-bindings'. This redefines many keys, mostly on the
+ `C-x' and `ESC' prefixes, to work as they do in Gosmacs. `M-x
+ set-gnu-bindings' returns to normal XEmacs by rebinding the same
+ keys to the definitions they had at the time `M-x
+ set-gosmacs-bindings' was done.
+
+ It is also possible to run Mocklisp code written for Gosling Emacs.

+Customization
+*************
+
+ This chapter talks about various topics relevant to adapting the
+behavior of Emacs in minor ways.
+
+ All kinds of customization affect only the particular Emacs job that
+you do them in. They are completely lost when you kill the Emacs job,
+and have no effect on other Emacs jobs you may run at the same time or
+later. The only way an Emacs job can affect anything outside of it is
+by writing a file; in particular, the only way to make a customization
+`permanent' is to put something in your init file or other appropriate
+file to do the customization in each session. *Note Init File::.
+
+* Menu:
+
+* Minor Modes:: Each minor mode is one feature you can turn on
+ independently of any others.
+* Variables:: Many Emacs commands examine Emacs variables
+ to decide what to do; by setting variables,
+ you can control their functioning.
+* Keyboard Macros:: A keyboard macro records a sequence of keystrokes
+ to be replayed with a single command.
+* Key Bindings:: The keymaps say what command each key runs.
+ By changing them, you can "redefine keys".
+* Syntax:: The syntax table controls how words and expressions
+ are parsed.
+* Init File:: How to write common customizations in the init file.
+* Audible Bell:: Changing how Emacs sounds the bell.
+* Faces:: Changing the fonts and colors of a region of text.

+File::). Don't try to use a local variable list that would impose your
+taste on everyone working with the file.
XEmacs allows you to specify local variables in the first line of a
file, in addition to specifying them in the `Local Variables' section
XEmacs uses the information between them to determine what the major
mode and variable settings should be. For example, these are all legal:
- ;;; -*- mode: emacs-lisp -*-
- ;;; -*- mode: postscript; version-control: never -*-
- ;;; -*- tags-file-name: "/foo/bar/TAGS" -*-
+ ;;; -*- mode: emacs-lisp -*-
+ ;;; -*- mode: postscript; version-control: never -*-
+ ;;; -*- tags-file-name: "/foo/bar/TAGS" -*-
For historical reasons, the syntax ``-*- modename -*-'' is allowed
as well; for example, you can use:
- ;;; -*- emacs-lisp -*-
+ ;;; -*- emacs-lisp -*-
The variable `enable-local-variables' controls the use of local
variables lists in files you visit. The value can be `t', `nil', or
so far. As a consequence it re-executes the macro as previously
defined.

-Naming and Saving Keyboard Macros
----------------------------------
-
- To save a keyboard macro for longer than until you define the next
-one, you must give it a name using `M-x name-last-kbd-macro'. This
-reads a name as an argument using the minibuffer and defines that name
-to execute the macro. The macro name is a Lisp symbol, and defining it
-in this way makes it a valid command name for calling with `M-x' or for
-binding a key to with `global-set-key' (*note Keymaps::.). If you
-specify a name that has a prior definition other than another keyboard
-macro, Emacs prints an error message and nothing is changed.
-
- Once a macro has a command name, you can save its definition in a
-file. You can then use it in another editing session. First visit the
-file you want to save the definition in. Then use the command:
-
- M-x insert-kbd-macro <RET> MACRONAME <RET>
-
-This inserts some Lisp code that, when executed later, will define the
-same macro with the same definition it has now. You need not
-understand Lisp code to do this, because `insert-kbd-macro' writes the
-Lisp code for you. Then save the file. You can load the file with
-`load-file' (*note Lisp Libraries::.). If the file you save in is your
-initialization file `~/.emacs' (*note Init File::.), then the macro
-will be defined each time you run Emacs.
-
- If you give `insert-kbd-macro' a prefix argument, it creates
-additional Lisp code to record the keys (if any) that you have bound to
-the keyboard macro, so that the macro is reassigned the same keys when
-you load the file.
-
-\1f
-File: xemacs.info, Node: Kbd Macro Query, Prev: Save Kbd Macro, Up: Keyboard Macros
-
-Executing Macros With Variations
---------------------------------
-
- You can use `C-x q' (`kbd-macro-query'), to get an effect similar to
-that of `query-replace'. The macro asks you each time whether to make
-a change. When you are defining the macro, type `C-x q' at the point
-where you want the query to occur. During macro definition, the `C-x
-q' does nothing, but when you invoke the macro, `C-x q' reads a
-character from the terminal to decide whether to continue.
-
- The special answers to a `C-x q' query are <SPC>, <DEL>, `C-d',
-`C-l', and `C-r'. Any other character terminates execution of the
-keyboard macro and is then read as a command. <SPC> means to continue.
-<DEL> means to skip the remainder of this repetition of the macro,
-starting again from the beginning in the next repetition. `C-d' means
-to skip the remainder of this repetition and cancel further repetition.
-`C-l' redraws the frame and asks you again for a character to specify
-what to do. `C-r' enters a recursive editing level, in which you can
-perform editing that is not part of the macro. When you exit the
-recursive edit using `C-M-c', you are asked again how to continue with
-the keyboard macro. If you type a <SPC> at this time, the rest of the
-macro definition is executed. It is up to you to leave point and the
-text in a state such that the rest of the macro will do what you want.
-
- `C-u C-x q', which is `C-x q' with a numeric argument, performs a
-different function. It enters a recursive edit reading input from the
-keyboard, both when you type it during the definition of the macro and
-when it is executed from the macro. During definition, the editing you
-do inside the recursive edit does not become part of the macro. During
-macro execution, the recursive edit gives you a chance to do some
-particularized editing. *Note Recursive Edit::.

-
-Keymaps
--------
-
- The bindings between characters and command functions are recorded in
-data structures called "keymaps". Emacs has many of these. One, the
-"global" keymap, defines the meanings of the single-character keys that
-are defined regardless of major mode. It is the value of the variable
-`global-map'.
-
- Each major mode has another keymap, its "local keymap", which
-contains overriding definitions for the single-character keys that are
-redefined in that mode. Each buffer records which local keymap is
-installed for it at any time, and the current buffer's local keymap is
-the only one that directly affects command execution. The local keymaps
-for Lisp mode, C mode, and many other major modes always exist even when
-not in use. They are the values of the variables `lisp-mode-map',
-`c-mode-map', and so on. For less frequently used major modes, the
-local keymap is sometimes constructed only when the mode is used for the
-first time in a session, to save space.
-
- There are local keymaps for the minibuffer, too; they contain various
-completion and exit commands.
-
- * `minibuffer-local-map' is used for ordinary input (no completion).
-
- * `minibuffer-local-ns-map' is similar, except that <SPC> exits just
- like <RET>. This is used mainly for Mocklisp compatibility.
-
- * `minibuffer-local-completion-map' is for permissive completion.
-
- * `minibuffer-local-must-match-map' is for strict completion and for
- cautious completion.
-
- * `repeat-complex-command-map' is for use in `C-x <ESC>'.
-
- * `isearch-mode-map' contains the bindings of the special keys which
- are bound in the pseudo-mode entered with `C-s' and `C-r'.
-
- Finally, each prefix key has a keymap which defines the key sequences
-that start with it. For example, `ctl-x-map' is the keymap used for
-characters following a `C-x'.
-
- * `ctl-x-map' is the variable name for the map used for characters
- that follow `C-x'.
-
- * `help-map' is used for characters that follow `C-h'.
-
- * `esc-map' is for characters that follow <ESC>. All Meta characters
- are actually defined by this map.
-
- * `ctl-x-4-map' is for characters that follow `C-x 4'.
-
- * `mode-specific-map' is for characters that follow `C-c'.
-
- The definition of a prefix key is the keymap to use for looking up
-the following character. Sometimes the definition is actually a Lisp
-symbol whose function definition is the following character keymap. The
-effect is the same, but it provides a command name for the prefix key
-that you can use as a description of what the prefix key is for. Thus
-the binding of `C-x' is the symbol `Ctl-X-Prefix', whose function
-definition is the keymap for `C-x' commands, the value of `ctl-x-map'.
-
- Prefix key definitions can appear in either the global map or a
-local map. The definitions of `C-c', `C-x', `C-h', and <ESC> as prefix
-keys appear in the global map, so these prefix keys are always
-available. Major modes can locally redefine a key as a prefix by
-putting a prefix key definition for it in the local map.
-
- A mode can also put a prefix definition of a global prefix character
-such as `C-x' into its local map. This is how major modes override the
-definitions of certain keys that start with `C-x'. This case is
-special, because the local definition does not entirely replace the
-global one. When both the global and local definitions of a key are
-other keymaps, the next character is looked up in both keymaps, with
-the local definition overriding the global one. The character after the
-`C-x' is looked up in both the major mode's own keymap for redefined
-`C-x' commands and in `ctl-x-map'. If the major mode's own keymap for
-`C-x' commands contains `nil', the definition from the global keymap
-for `C-x' commands is used.

-Changing Key Bindings
----------------------
-
- You can redefine an Emacs key by changing its entry in a keymap.
-You can change the global keymap, in which case the change is effective
-in all major modes except those that have their own overriding local
-definitions for the same key. Or you can change the current buffer's
-local map, which affects all buffers using the same major mode.

-...................................
-
-`M-x global-set-key <RET> KEY CMD <RET>'
- Defines KEY globally to run CMD.
-
-`M-x local-set-key <RET> KEYS CMD <RET>'
- Defines KEY locally (in the major mode now in effect) to run CMD.
-
-`M-x local-unset-key <RET> KEYS <RET>'
- Removes the local binding of KEY.
-
- CMD is a symbol naming an interactively-callable function.
-
- When called interactively, KEY is the next complete key sequence
-that you type. When called as a function, KEY is a string, a vector of
-events, or a vector of key-description lists as described in the
-`define-key' function description. The binding goes in the current
-buffer's local map, which is shared with other buffers in the same
-major mode.
-
- The following example:
-
- M-x global-set-key <RET> C-f next-line <RET>
-
-redefines `C-f' to move down a line. The fact that CMD is read second
-makes it serve as a kind of confirmation for KEY.
-
- These functions offer no way to specify a particular prefix keymap as
-the one to redefine in, but that is not necessary, as you can include
-prefixes in KEY. KEY is read by reading characters one by one until
-they amount to a complete key (that is, not a prefix key). Thus, if
-you type `C-f' for KEY, Emacs enters the minibuffer immediately to read
-CMD. But if you type `C-x', another character is read; if that
-character is `4', another character is read, and so on. For example,
-
- M-x global-set-key <RET> C-x 4 $ spell-other-window <RET>
-
-redefines `C-x 4 $' to run the (fictitious) command
-`spell-other-window'.
-
- The most general way to modify a keymap is the function
-`define-key', used in Lisp code (such as your `.emacs' file).
-`define-key' takes three arguments: the keymap, the key to modify in
-it, and the new definition. *Note Init File::, for an example.
-`substitute-key-definition' is used similarly; it takes three
-arguments, an old definition, a new definition, and a keymap, and
-redefines in that keymap all keys that were previously defined with the
-old definition to have the new definition instead.

-Changing Key Bindings Programmatically
-......................................
-
- You can use the functions `global-set-key' and `define-key' to
-rebind keys under program control.
-
-``(global-set-key KEYS CMD)''
- Defines KEYS globally to run CMD.
-
-``(define-key KEYMAP KEYS DEF)''
- Defines KEYS to run DEF in the keymap KEYMAP.
-
- KEYMAP is a keymap object.
-
- KEYS is the sequence of keystrokes to bind.
-
- DEF is anything that can be a key's definition:
-
- * `nil', meaning key is undefined in this keymap
-
- * A command, that is, a Lisp function suitable for interactive
- calling
-
- * A string or key sequence vector, which is treated as a keyboard
- macro
-
- * A keymap to define a prefix key
-
- * A symbol so that when the key is looked up, the symbol stands for
- its function definition, which should at that time be one of the
- above, or another symbol whose function definition is used, and so
- on
-
- * A cons, `(string . defn)', meaning that DEFN is the definition
- (DEFN should be a valid definition in its own right)
-
- * A cons, `(keymap . char)', meaning use the definition of CHAR in
- map KEYMAP
-
- For backward compatibility, XEmacs allows you to specify key
-sequences as strings. However, the preferred method is to use the
-representations of key sequences as vectors of keystrokes. *Note
-Keystrokes::, for more information about the rules for constructing key
-sequences.
-
- Emacs allows you to abbreviate representations for key sequences in
-most places where there is no ambiguity. Here are some rules for
-abbreviation:
-
- * The keysym by itself is equivalent to a list of just that keysym,
- i.e., `f1' is equivalent to `(f1)'.
-
- * A keystroke by itself is equivalent to a vector containing just
- that keystroke, i.e., `(control a)' is equivalent to `[(control
- a)]'.
-
- * You can use ASCII codes for keysyms that have them. i.e., `65' is
- equivalent to `A'. (This is not so much an abbreviation as an
- alternate representation.)
-
- Here are some examples of programmatically binding keys:
-
-
- ;;; Bind `my-command' to <f1>
- (global-set-key 'f1 'my-command)
-
- ;;; Bind `my-command' to Shift-f1
- (global-set-key '(shift f1) 'my-command)
-
- ;;; Bind `my-command' to C-c Shift-f1
- (global-set-key '[(control c) (shift f1)] 'my-command)
-
- ;;; Bind `my-command' to the middle mouse button.
- (global-set-key 'button2 'my-command)
-
- ;;; Bind `my-command' to <META> <CTL> <Right Mouse Button>
- ;;; in the keymap that is in force when you are running `dired'.
- (define-key dired-mode-map '(meta control button3) 'my-command)

-Using Strings for Changing Key Bindings
-.......................................
-
- For backward compatibility, you can still use strings to represent
-key sequences. Thus you can use commands like the following:
-
- ;;; Bind `end-of-line' to C-f
- (global-set-key "\C-f" 'end-of-line)
-
- Note, however, that in some cases you may be binding more than one
-key sequence by using a single command. This situation can arise
-because in ASCII, `C-i' and <TAB> have the same representation.
-Therefore, when Emacs sees:
-
- (global-set-key "\C-i" 'end-of-line)
-
- it is unclear whether the user intended to bind `C-i' or <TAB>. The
-solution XEmacs adopts is to bind both of these key sequences.
-
- After binding a command to two key sequences with a form like:
-
- (define-key global-map "\^X\^I" 'command-1)
-
- it is possible to redefine only one of those sequences like so:
-
- (define-key global-map [(control x) (control i)] 'command-2)
- (define-key global-map [(control x) tab] 'command-3)
-
- This applies only when running under a window system. If you are
-talking to Emacs through an ASCII-only channel, you do not get any of
-these features.
-
- Here is a table of pairs of key sequences that behave in a similar
-fashion:
-
- control h backspace
- control l clear
- control i tab
- control m return
- control j linefeed
- control [ escape
- control @ control space
