40.SH DESCRIPTION
41.LP
42.B readline
43will read a line from the terminal
44and return it, using
45.B prompt
46as a prompt. If
47.B prompt
48is null, no prompt is issued. The line returned is allocated with
49.IR malloc (3),
50so the caller must free it when finished. The line returned
51has the final newline removed, so only the text of the line
52remains.
53.LP
54.B readline
55offers editing capabilities while the user is entering the
56line.
57By default, the line editing commands
58are similar to those of emacs.
59A vi\-style line editing interface is also available.
60.SH RETURN VALUE
61.LP
62.B readline
63returns the text of the line read. A blank line
64returns the empty string. If
65.B EOF
66is encountered while reading a line, and the line is empty,
67.B NULL
68is returned. If an
69.B EOF
70is read with a non\-empty line, it is
71treated as a newline.
72.SH NOTATION
73.LP
74An emacs-style notation is used to denote
75keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n
76means Control\-N. Similarly,
77.I meta
78keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards
79without a
80.I meta
81key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key
82then the
83.I x
84key. This makes ESC the \fImeta prefix\fP.
85The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP,
86or press the Escape key
87then hold the Control key while pressing the
88.I x
89key.)
90.PP
91Readline commands may be given numeric
92.IR arguments ,
93which normally act as a repeat count. Sometimes, however, it is the
94sign of the argument that is significant. Passing a negative argument
95to a command that acts in the forward direction (e.g., \fBkill\-line\fP)
96causes that command to act in a backward direction. Commands whose
97behavior with arguments deviates from this are noted.
98.PP
99When a command is described as \fIkilling\fP text, the text
100deleted is saved for possible future retrieval
101(\fIyanking\fP). The killed text is saved in a
102\fIkill ring\fP. Consecutive kills cause the text to be
103accumulated into one unit, which can be yanked all at once.
104Commands which do not kill text separate the chunks of text
105on the kill ring.
106.SH INITIALIZATION FILE
107.LP
108Readline is customized by putting commands in an initialization
109file (the \fIinputrc\fP file).
110The name of this file is taken from the value of the
111.B INPUTRC
112environment variable. If that variable is unset, the default is
113.IR ~/.inputrc .
114When a program which uses the readline library starts up, the
115init file is read, and the key bindings and variables are set.
116There are only a few basic constructs allowed in the
117readline init file. Blank lines are ignored.
118Lines beginning with a \fB#\fP are comments.
119Lines beginning with a \fB$\fP indicate conditional constructs.
120Other lines denote key bindings and variable settings.
121Each program using this library may add its own commands
122and bindings.
123.PP
124For example, placing
125.RS
126.PP
127M\-Control\-u: universal\-argument
128.RE
129or

133into the
134.I inputrc
135would make M\-C\-u execute the readline command
136.IR universal\-argument .
137.PP
138The following symbolic character names are recognized while
139processing key bindings:
140.IR RUBOUT ,
141.IR DEL ,
142.IR ESC ,
143.IR LFD ,
144.IR NEWLINE ,

151In addition to command names, readline allows keys to be bound
152to a string that is inserted when the key is pressed (a \fImacro\fP).
153.PP
154.SS Key Bindings
155.PP
156The syntax for controlling key bindings in the
157.I inputrc
158file is simple. All that is required is the name of the
159command or the text of a macro and a key sequence to which
160it should be bound. The name may be specified in one of two ways:
161as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
162prefixes, or as a key sequence.
163When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
164.I keyname
165is the name of a key spelled out in English. For example:
166.sp
167.RS
168Control\-u: universal\-argument
169.br
170Meta\-Rubout: backward\-kill\-word
171.br
172Control\-o: ">&output"
173.RE
174.LP
175In the above example,
176.I C\-u
177is bound to the function
178.BR universal\-argument ,
179.I M-DEL
180is bound to the function
181.BR backward\-kill\-word ,
182and
183.I C\-o
184is bound to run the macro
185expressed on the right hand side (that is, to insert the text
186.I >&output
187into the line).
188.PP
189In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
190.B keyseq
191differs from
192.B keyname
193above in that strings denoting
194an entire key sequence may be specified by placing the sequence
195within double quotes. Some GNU Emacs style key escapes can be
196used, as in the following example.
197.sp
198.RS
199"\eC\-u": universal\-argument
200.br
201"\eC\-x\eC\-r": re\-read\-init\-file
202.br
203"\ee[11~": "Function Key 1"
204.RE
205.PP
206In this example,
207.I C-u
208is again bound to the function
209.BR universal\-argument .
210.I "C-x C-r"
211is bound to the function
212.BR re\-read\-init\-file ,
213and
214.I "ESC [ 1 1 ~"
215is bound to insert the text
216.BR "Function Key 1" .
217The full set of GNU Emacs style escape sequences is
218.RS

238.RE
239.PD
240.PP
241In addition to the GNU Emacs style escape sequences, a second
242set of backslash escapes is available:

269.TP
270.B \e\fInnn\fP
271the character whose ASCII code is the octal value \fInnn\fP
272(one to three digits)
273.TP
274.B \ex\fInnn\fP
275the character whose ASCII code is the hexadecimal value \fInnn\fP
276(one to three digits)
277.RE
278.PD
279.PP
280When entering the text of a macro, single or double quotes should
281be used to indicate a macro definition. Unquoted text
282is assumed to be a function name.
283In the macro body, the backslash escapes described above are expanded.
284Backslash will quote any other character in the macro text,
285including " and '.
286.PP
287.B Bash
288allows the current readline key bindings to be displayed or modified
289with the
290.B bind
291builtin command. The editing mode may be switched during interactive
292use by using the
293.B \-o
294option to the
295.B set
296builtin command. Other programs using this library provide
297similar mechanisms. The
298.I inputrc
299file may be edited and re-read if a program does not provide
300any other means to incorporate new bindings.
301.SS Variables
302.PP
303Readline has variables that can be used to further customize its
304behavior. A variable may be set in the
305.I inputrc
306file with a statement of the form
307.RS
308.PP
309\fBset\fP \fIvariable\-name\fP \fIvalue\fP
310.RE
311.PP
312Except where noted, readline variables can take the values
313.B On
314or
315.BR Off .
316The variables and their default values are:
317.PP
318.PD 0
319.TP
320.B bell\-style (audible)
321Controls what happens when readline wants to ring the terminal bell.
322If set to \fBnone\fP, readline never rings the bell. If set to
323\fBvisible\fP, readline uses a visible bell if one is available.
324If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
325.TP
326.B comment\-begin (``#'')
327The string that is inserted in \fBvi\fP mode when the
328.B insert\-comment
329command is executed.
330This command is bound to
331.B M\-#
332in emacs mode and to
333.B #
334in vi command mode.
335.TP
336.B completion\-ignore\-case (Off)
337If set to \fBOn\fP, readline performs filename matching and completion
338in a case\-insensitive fashion.
339.TP
340.B completion\-query\-items (100)
341This determines when the user is queried about viewing
342the number of possible completions
343generated by the \fBpossible\-completions\fP command.
344It may be set to any integer value greater than or equal to
345zero. If the number of possible completions is greater than
346or equal to the value of this variable, the user is asked whether
347or not he wishes to view them; otherwise they are simply listed
348on the terminal.
349.TP
350.B convert\-meta (On)
351If set to \fBOn\fP, readline will convert characters with the
352eighth bit set to an ASCII key sequence
353by stripping the eighth bit and prepending an
354escape character (in effect, using escape as the \fImeta prefix\fP).
355.TP
356.B disable\-completion (Off)
357If set to \fBOn\fP, readline will inhibit word completion. Completion
358characters will be inserted into the line as if they had been
359mapped to \fBself-insert\fP.
360.TP
361.B editing\-mode (emacs)
362Controls whether readline begins with a set of key bindings similar
363to \fIemacs\fP or \fIvi\fP.
364.B editing\-mode
365can be set to either
366.B emacs
367or
368.BR vi .
369.TP
370.B enable\-keypad (Off)
371When set to \fBOn\fP, readline will try to enable the application
372keypad when it is called. Some systems need this to enable the
373arrow keys.
374.TP
375.B expand\-tilde (Off)
376If set to \fBon\fP, tilde expansion is performed when readline
377attempts word completion.
378.TP
379.B horizontal\-scroll\-mode (Off)
380When set to \fBOn\fP, makes readline use a single line for display,
381scrolling the input horizontally on a single screen line when it
382becomes longer than the screen width rather than wrapping to a new line.
383.TP
384.B input\-meta (Off)
385If set to \fBOn\fP, readline will enable eight-bit input (that is,
386it will not strip the high bit from the characters it reads),
387regardless of what the terminal claims it can support. The name
388.B meta\-flag
389is a synonym for this variable.
390.TP
391.B isearch\-terminators (``C\-[C\-J'')
392The string of characters that should terminate an incremental
393search without subsequently executing the character as a command.
394If this variable has not been given a value, the characters
395\fIESC\fP and \fIC\-J\fP will terminate an incremental search.
396.TP
397.B keymap (emacs)
398Set the current readline keymap. The set of legal keymap names is
399\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
400vi-command\fP, and
401.IR vi-insert .
402\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
403equivalent to \fIemacs-standard\fP. The default value is
404.IR emacs ;
405the value of
406.B editing\-mode
407also affects the default keymap.
408.TP
409.B mark\-directories (On)
410If set to \fBOn\fP, complete<d directory names have a slash
411appended.
412.TP
413.B mark\-modified\-lines (Off)
414If set to \fBOn\fP, history lines that have been modified are displayed
415with a preceding asterisk (\fB*\fP).
416.TP
417.B output\-meta (Off)
418If set to \fBOn\fP, readline will display characters with the
419eighth bit set directly rather than as a meta-prefixed escape
420sequence.
421.TP
422.B print\-completions\-horizontally (Off)
423If set to \fBOn\fP, readline will display completions with matches
424sorted horizontally in alphabetical order, rather than down the screen.
425.TP
426.B show\-all\-if\-ambiguous (Off)
427This alters the default behavior of the completion functions. If
428set to
429.BR on ,
430words which have more than one possible completion cause the
431matches to be listed immediately instead of ringing the bell.
432.TP
433.B visible\-stats (Off)
434If set to \fBOn\fP, a character denoting a file's type as reported
435by \fBstat\fP(2) is appended to the filename when listing possible
436completions.
437.PD
438.SS Conditional Constructs
439.PP
440Readline implements a facility similar in spirit to the conditional
441compilation features of the C preprocessor which allows key
442bindings and variable settings to be performed as the result
443of tests. There are four parser directives used.
444.IP \fB$if\fP
445The
446.B $if
447construct allows bindings to be made based on the
448editing mode, the terminal being used, or the application using
449readline. The text of the test extends to the end of the line;
450no characters are required to isolate it.
451.RS
452.IP \fBmode\fP
453The \fBmode=\fP form of the \fB$if\fP directive is used to test
454whether readline is in emacs or vi mode.
455This may be used in conjunction
456with the \fBset keymap\fP command, for instance, to set bindings in
457the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
458readline is starting out in emacs mode.
459.IP \fBterm\fP
460The \fBterm=\fP form may be used to include terminal-specific
461key bindings, perhaps to bind the key sequences output by the
462terminal's function keys. The word on the right side of the
463.B =
464is tested against the full name of the terminal and the portion
465of the terminal name before the first \fB\-\fP. This allows
466.I sun
467to match both
468.I sun
469and
470.IR sun\-cmd ,
471for instance.
472.IP \fBapplication\fP
473The \fBapplication\fP construct is used to include

506.SH SEARCHING
507.PP
508Readline provides commands for searching through the command history
509for lines containing a specified string.
510There are two search modes:
511.I incremental
512and
513.IR non-incremental .
514.PP
515Incremental searches begin before the user has finished typing the
516search string.
517As each character of the search string is typed, readline displays
518the next entry from the history matching the string typed so far.
519An incremental search requires only as many characters as needed to
520find the desired history entry.
521The characters present in the value of the \fIisearch-terminators\fP
522variable are used to terminate an incremental search.
523If that variable has not been assigned a value the Escape and
524Control-J characters will terminate an incremental search.
525Control-G will abort an incremental search and restore the original
526line.
527When the search is terminated, the history entry containing the
528search string becomes the current line.
529To find other matching entries in the history list, type Control-S or
530Control-R as appropriate.
531This will search backward or forward in the history for the next
532line matching the search string typed so far.
533Any other key sequence bound to a readline command will terminate
534the search and execute that command.
535For instance, a \fInewline\fP will terminate the search and accept
536the line, thereby executing the command from the history list.
537.PP
538Non-incremental searches read the entire search string before starting
539to search for matching history lines. The search string may be
540typed by the user or be part of the contents of the current line.

156.SS Key Bindings
157.PP
158The syntax for controlling key bindings in the
159.I inputrc
160file is simple. All that is required is the name of the
161command or the text of a macro and a key sequence to which
162it should be bound. The name may be specified in one of two ways:
163as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP
164prefixes, or as a key sequence.
165When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP,
166.I keyname
167is the name of a key spelled out in English. For example:
168.sp
169.RS
170Control\-u: universal\-argument
171.br
172Meta\-Rubout: backward\-kill\-word
173.br
174Control\-o: ">&output"
175.RE
176.LP
177In the above example,
178.I C\-u
179is bound to the function
180.BR universal\-argument ,
181.I M-DEL
182is bound to the function
183.BR backward\-kill\-word ,

185.I C\-o
186is bound to run the macro
187expressed on the right hand side (that is, to insert the text
188.I >&output
189into the line).
190.PP
191In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP,
192.B keyseq
193differs from
194.B keyname
195above in that strings denoting
196an entire key sequence may be specified by placing the sequence
197within double quotes. Some GNU Emacs style key escapes can be
198used, as in the following example.
199.sp
200.RS
201"\eC\-u": universal\-argument
202.br

322.B bell\-style (audible)
323Controls what happens when readline wants to ring the terminal bell.
324If set to \fBnone\fP, readline never rings the bell. If set to
325\fBvisible\fP, readline uses a visible bell if one is available.
326If set to \fBaudible\fP, readline attempts to ring the terminal's bell.
327.TP
328.B comment\-begin (``#'')
329The string that is inserted in \fBvi\fP mode when the
330.B insert\-comment
331command is executed.
332This command is bound to
333.B M\-#
334in emacs mode and to
335.B #
336in vi command mode.
337.TP
338.B completion\-ignore\-case (Off)
339If set to \fBOn\fP, readline performs filename matching and completion
340in a case\-insensitive fashion.
341.TP
342.B completion\-query\-items (100)
343This determines when the user is queried about viewing
344the number of possible completions
345generated by the \fBpossible\-completions\fP command.
346It may be set to any integer value greater than or equal to
347zero. If the number of possible completions is greater than
348or equal to the value of this variable, the user is asked whether
349or not he wishes to view them; otherwise they are simply listed
350on the terminal.
351.TP
352.B convert\-meta (On)
353If set to \fBOn\fP, readline will convert characters with the
354eighth bit set to an ASCII key sequence
355by stripping the eighth bit and prepending an
356escape character (in effect, using escape as the \fImeta prefix\fP).
357.TP
358.B disable\-completion (Off)
359If set to \fBOn\fP, readline will inhibit word completion. Completion
360characters will be inserted into the line as if they had been
361mapped to \fBself-insert\fP.
362.TP
363.B editing\-mode (emacs)
364Controls whether readline begins with a set of key bindings similar
365to \fIemacs\fP or \fIvi\fP.

370.BR vi .
371.TP
372.B enable\-keypad (Off)

377.B expand\-tilde (Off)
378If set to \fBon\fP, tilde expansion is performed when readline
379attempts word completion.
380.TP
381.B horizontal\-scroll\-mode (Off)
382When set to \fBOn\fP, makes readline use a single line for display,
383scrolling the input horizontally on a single screen line when it
384becomes longer than the screen width rather than wrapping to a new line.
385.TP
386.B input\-meta (Off)
387If set to \fBOn\fP, readline will enable eight-bit input (that is,
388it will not strip the high bit from the characters it reads),
389regardless of what the terminal claims it can support. The name
390.B meta\-flag
391is a synonym for this variable.
392.TP
393.B isearch\-terminators (``C\-[C\-J'')
394The string of characters that should terminate an incremental
395search without subsequently executing the character as a command.
396If this variable has not been given a value, the characters
397\fIESC\fP and \fIC\-J\fP will terminate an incremental search.
398.TP
399.B keymap (emacs)
400Set the current readline keymap. The set of legal keymap names is
401\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,
402vi-command\fP, and
403.IR vi-insert .
404\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is
405equivalent to \fIemacs-standard\fP. The default value is
406.IR emacs ;

417with a preceding asterisk (\fB*\fP).
418.TP
419.B output\-meta (Off)

421eighth bit set directly rather than as a meta-prefixed escape
422sequence.
423.TP
424.B print\-completions\-horizontally (Off)
425If set to \fBOn\fP, readline will display completions with matches
426sorted horizontally in alphabetical order, rather than down the screen.
427.TP
428.B show\-all\-if\-ambiguous (Off)
429This alters the default behavior of the completion functions. If
430set to
431.BR on ,
432words which have more than one possible completion cause the
433matches to be listed immediately instead of ringing the bell.
434.TP
435.B visible\-stats (Off)
436If set to \fBOn\fP, a character denoting a file's type as reported
437by \fBstat\fP(2) is appended to the filename when listing possible
438completions.
439.PD
440.SS Conditional Constructs
441.PP
442Readline implements a facility similar in spirit to the conditional
443compilation features of the C preprocessor which allows key
444bindings and variable settings to be performed as the result
445of tests. There are four parser directives used.
446.IP \fB$if\fP
447The
448.B $if
449construct allows bindings to be made based on the
450editing mode, the terminal being used, or the application using
451readline. The text of the test extends to the end of the line;
452no characters are required to isolate it.
453.RS
454.IP \fBmode\fP
455The \fBmode=\fP form of the \fB$if\fP directive is used to test
456whether readline is in emacs or vi mode.
457This may be used in conjunction
458with the \fBset keymap\fP command, for instance, to set bindings in
459the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if
460readline is starting out in emacs mode.
461.IP \fBterm\fP
462The \fBterm=\fP form may be used to include terminal-specific
463key bindings, perhaps to bind the key sequences output by the
464terminal's function keys. The word on the right side of the
465.B =
466is tested against the full name of the terminal and the portion
467of the terminal name before the first \fB\-\fP. This allows
468.I sun
469to match both
470.I sun
471and
472.IR sun\-cmd ,
473for instance.
474.IP \fBapplication\fP
475The \fBapplication\fP construct is used to include
476application-specific settings. Each program using the readline
477library sets the \fIapplication name\fP, and an initialization
478file can test for a particular value.
479This could be used to bind key sequences to functions useful for
480a specific program. For instance, the following command adds a
481key sequence that quotes the current or previous word in Bash:
482.sp 1
483.RS
484.nf
485\fB$if\fP bash
486# Quote the current or previous word

492.IP \fB$endif\fP
493This command, as seen in the previous example, terminates an

495.IP \fB$else\fP
496Commands in this branch of the \fB$if\fP directive are executed if
497the test fails.
498.IP \fB$include\fP
499This directive takes a single filename as an argument and reads commands
500and bindings from that file. For example, the following directive
501would read \fI/etc/inputrc\fP:

765.B universal\-argument
766This is another way to specify an argument.
767If this command is followed by one or more digits, optionally with a

769If the command is followed by digits, executing
770.B universal\-argument
771again ends the numeric argument, but is otherwise ignored.
772As a special case, if this command is immediately followed by a
773character that is neither a digit or minus sign, the argument count
774for the next command is multiplied by four.
775The argument count is initially one, so executing this function the
776first time makes the argument count four, a second time makes the
777argument count sixteen, and so on.

790command (including aliases and functions) in turn. If none

805.B menu\-complete
806Similar to \fBcomplete\fP, but replaces the word to be completed
807with a single match from the list of possible completions.
808Repeated execution of \fBmenu\-complete\fP steps through the list
809of possible completions, inserting each match in turn.
810At the end of the list of completions, the bell is rung and the
811original text is restored.
812An argument of \fIn\fP moves \fIn\fP positions forward in the list
813of matches; a negative argument may be used to move backward

933The following is a list of the default emacs and vi bindings.
934Characters with the 8th bit set are written as M\-<character>, and
935are referred to as
936.I metafied
937characters.
938The printable ASCII characters not mentioned in the list of emacs
939standard bindings are bound to the
940.I self\-insert
941function, which just inserts the given character into the input line.
942In vi insertion mode, all characters not specifically mentioned are
943bound to
944.IR self\-insert .
945Characters assigned to signal generation by
946.IR stty (1)
947or the terminal driver, such as C-Z or C-C,
948retain that function.
949Upper and lower case
950.I metafied
951characters are bound to the same function in the emacs mode
952meta keymap.
953The remaining characters are unbound, which causes readline
954to ring the bell (subject to the setting of the
955.B bell\-style
956variable).

622between the start of the current line and the current cursor
623position (the \fIpoint\fP).
624This is a non-incremental search.
625.TP
626.B history\-search\-backward
627Search backward through the history for the string of characters
628between the start of the current line and the point.
629This is a non-incremental search.

631.B yank\-nth\-arg (M\-C\-y)
632Insert the first argument to the previous command (usually
633the second word on the previous line) at point (the current
634cursor position). With an argument
635.IR n ,
636insert the \fIn\fPth word from the previous command (the words
637in the previous command begin with word 0). A negative argument
638inserts the \fIn\fPth word from the end of the previous command.

663.B forward\-backward\-delete\-char
664Delete the character under the cursor, unless the cursor is at the
665end of the line, in which case the character behind the cursor is
666deleted. By default, this is not bound to a key.
667.TP
668.B quoted\-insert (C\-q, C\-v)

763.B digit\-argument (M\-0, M\-1, ..., M\-\-)
764Add this digit to the argument already accumulating, or start a new
765argument. M\-\- starts a negative argument.
766.TP
767.B universal\-argument
768This is another way to specify an argument.
769If this command is followed by one or more digits, optionally with a
770leading minus sign, those digits define the argument.
771If the command is followed by digits, executing
772.B universal\-argument
773again ends the numeric argument, but is otherwise ignored.
774As a special case, if this command is immediately followed by a
775character that is neither a digit or minus sign, the argument count
776for the next command is multiplied by four.
777The argument count is initially one, so executing this function the
778first time makes the argument count four, a second time makes the
779argument count sixteen, and so on.

787The actual completion performed is application-specific.
788.BR Bash ,
789for instance, attempts completion treating the text as a variable
790(if the text begins with \fB$\fP), username (if the text begins with
791\fB~\fP), hostname (if the text begins with \fB@\fP), or
792command (including aliases and functions) in turn. If none
793of these produces a match, filename completion is attempted.

795on the other hand,
796allows completion of program functions and variables, and
797only attempts filename completion under certain circumstances.

804that would have been generated by
805\fBpossible\-completions\fP.
806.TP
807.B menu\-complete
808Similar to \fBcomplete\fP, but replaces the word to be completed
809with a single match from the list of possible completions.
810Repeated execution of \fBmenu\-complete\fP steps through the list
811of possible completions, inserting each match in turn.
812At the end of the list of completions, the bell is rung and the
813original text is restored.
814An argument of \fIn\fP moves \fIn\fP positions forward in the list
815of matches; a negative argument may be used to move backward
816through the list.
817This command is intended to be bound to \fBTAB\fP, but is unbound
818by default.
819.TP
820.B delete\-char\-or\-list
821Deletes the character under the cursor if not at the beginning or

935The following is a list of the default emacs and vi bindings.
936Characters with the 8th bit set are written as M\-<character>, and
937are referred to as
938.I metafied
939characters.
940The printable ASCII characters not mentioned in the list of emacs
941standard bindings are bound to the
942.I self\-insert
943function, which just inserts the given character into the input line.
944In vi insertion mode, all characters not specifically mentioned are
945bound to
946.IR self\-insert .
947Characters assigned to signal generation by
948.IR stty (1)
949or the terminal driver, such as C-Z or C-C,
950retain that function.
951Upper and lower case
952.I metafied
953characters are bound to the same function in the emacs mode
954meta keymap.
955The remaining characters are unbound, which causes readline
956to ring the bell (subject to the setting of the
957.B bell\-style
958variable).
