-x

i.e. press the Escape key then the x key. This makes ESC the meta prefix

-Meta-u:

into the inputrc would make M-C-u execute the readline command universal-argument.The following symbolic character names are recognized while processing key bindings: DEL, ESC, ESCAPE, LFD,NEWLINE, RET, RETURN, RUBOUT, SPACE, SPC, and TAB.In addition to command names, readline allows keys to be bound to a string that is inserted when the key ispressed (a macro).Key BindingsThe syntax for controlling key bindings in the inputrc file is simple. All that is required is the name ofthe command or the text of a macro and a key sequence to which it should be bound. The name may be specifiedin one of two ways: as a symbolic key name, possibly with Meta- or Control- prefixes, or as a key sequence.The name and key sequence are separated by a colon. There can be no whitespace between the name and thecolon.When using the form keyname:function-name or macro, keyname is the name of a key spelled out in English. Forexample:Control-u: universal-argumentMeta-Rubout: backward-kill-wordControl-o: "> output"In the above example, C-u is bound to the function universal-argument, M-DEL is bound to the function back‐ward-kill-word, and C-o is bound to run the macro expressed on the right hand side (that is, to insert thetext ``> output'' into the line).In the second form, "keyseq":function-name or macro, keyseq differs from keyname above in that strings denot‐ing an entire key sequence may be specified by placing the sequence within double quotes. Some GNU Emacsstyle key escapes can be used, as in the following example, but the symbolic character names are not recog‐nized."\C-u": universal-argument"\C-x\C-r": re-read-init-file"\e[11~": "Function Key 1"In this example, C-u is again bound to the function universal-argument. C-x C-r is bound to the functionre-read-init-file, and ESC [ 1 1 ~ is bound to insert the text ``Function Key 1''.The full set of GNU Emacs style escape sequences available when specifying key sequences is\C- control prefix\M- meta prefix\e an escape character\\ backslash\" literal ", a double quote\' literal ', a single quoteIn addition to the GNU Emacs style escape sequences, a second set of backslash escapes is available:\a alert (bell)\b backspace\d delete\f form feed\n newline\r carriage return\t horizontal tab\v vertical tab\nnn the eight-bit character whose value is the octal value nnn (one to three digits)\xHH the eight-bit character whose value is the hexadecimal value HH (one or two hex digits)When entering the text of a macro, single or double quotes should be used to indicate a macro definition.Unquoted text is assumed to be a function name. In the macro body, the backslash escapes described above areexpanded. Backslash will quote any other character in the macro text, including " and '.Bash allows the current readline key bindings to be displayed or modified with the bind builtin command. Theediting mode may be switched during interactive use by using the -o option to the set builtin command. Otherprograms using this library provide similar mechanisms. The inputrc file may be edited and re-read if a pro‐gram does not provide any other means to incorporate new bindings.VariablesReadline has variables that can be used to further customize its behavior. A variable may be set in the inpu‐trc file with a statement of the formset variable-name valueExcept where noted, readline variables can take the values On or Off (without regard to case). Unrecognizedvariable names are ignored. When a variable value is read, empty or null values, "on" (case-insensitive), and"1" are equivalent to On. All other values are equivalent to Off. The variables and their default valuesare:bell-style (audible)Controls what happens when readline wants to ring the terminal bell. If set to none, readline neverrings the bell. If set to visible, readline uses a visible bell if one is available. If set to audi‐ble, readline attempts to ring the terminal's bell.bind-tty-special-chars (On)If set to On (the default), readline attempts to bind the control characters treated specially by thekernel's terminal driver to their readline equivalents.blink-matching-paren (Off)If set to On, readline attempts to briefly move the cursor to an opening parenthesis when a closingparenthesis is inserted.colored-completion-prefix (Off)If set to On, when listing completions, readline displays the common prefix of the set of possible com‐pletions using a different color. The color definitions are taken from the value of the LS_COLORSenvironment variable.colored-stats (Off)If set to On, readline displays possible completions using different colors to indicate their filetype. The color definitions are taken from the value of the LS_COLORS environment variable.comment-begin (``#'')The string that is inserted in vi mode when the insert-comment command is executed. This command isbound to M-# in emacs mode and to # in vi command mode.completion-display-width (-1)The number of screen columns used to display possible matches when performing completion. The value isignored if it is less than 0 or greater than the terminal screen width. A value of 0 will causematches to be displayed one per line. The default value is -1.completion-ignore-case (Off)If set to On, readline performs filename matching and completion in a case-insensitive fashion.completion-map-case (Off)If set to On, and completion-ignore-case is enabled, readline treats hyphens (-) and underscores (_) asequivalent when performing case-insensitive filename matching and completion.completion-prefix-display-length (0)The length in characters of the common prefix of a list of possible completions that is displayed with‐out modification. When set to a value greater than zero, common prefixes longer than this value arereplaced with an ellipsis when displaying possible completions.completion-query-items (100)This determines when the user is queried about viewing the number of possible completions generated bythe possible-completions command. It may be set to any integer value greater than or equal to zero.If the number of possible completions is greater than or equal to the value of this variable, the useris asked whether or not he wishes to view them; otherwise they are simply listed on the terminal. Anegative value causes readline to never ask.convert-meta (On)If set to On, readline will convert characters with the eighth bit set to an ASCII key sequence bystripping the eighth bit and prefixing it with an escape character (in effect, using escape as the metaprefix). The default is On, but readline will set it to Off if the locale contains eight-bit charac‐ters.disable-completion (Off)If set to On, readline will inhibit word completion. Completion characters will be inserted into theline as if they had been mapped to self-insert.echo-control-characters (On)When set to On, on operating systems that indicate they support it, readline echoes a character corre‐sponding to a signal generated from the keyboard.editing-mode (emacs)Controls whether readline begins with a set of key bindings similar to Emacs or vi. editing-mode canbe set to either emacs or vi.enable-bracketed-paste (Off)When set to On, readline will configure the terminal in a way that will enable it to insert each pasteinto the editing buffer as a single string of characters, instead of treating each character as if ithad been read from the keyboard. This can prevent pasted characters from being interpreted as editingcommands.enable-keypad (Off)When set to On, readline will try to enable the application keypad when it is called. Some systemsneed this to enable the arrow keys.enable-meta-key (On)When set to On, readline will try to enable any meta modifier key the terminal claims to support whenit is called. On many terminals, the meta key is used to send eight-bit characters.expand-tilde (Off)If set to On, tilde expansion is performed when readline attempts word completion.history-preserve-point (Off)If set to On, the history code attempts to place point at the same location on each history lineretrieved with previous-history or next-history.history-size (unset)Set the maximum number of history entries saved in the history list. If set to zero, any existing his‐tory entries are deleted and no new entries are saved. If set to a value less than zero, the number ofhistory entries is not limited. By default, the number of history entries is not limited. If anattempt is made to set history-size to a non-numeric value, the maximum number of history entries willbe set to 500.horizontal-scroll-mode (Off)When set to On, makes readline use a single line for display, scrolling the input horizontally on asingle screen line when it becomes longer than the screen width rather than wrapping to a new line.input-meta (Off)If set to On, readline will enable eight-bit input (that is, it will not clear the eighth bit in thecharacters it reads), regardless of what the terminal claims it can support. The name meta-flag is asynonym for this variable. The default is Off, but readline will set it to On if the locale containseight-bit characters.isearch-terminators (``C-[ C-J'')The string of characters that should terminate an incremental search without subsequently executing thecharacter as a command. If this variable has not been given a value, the characters ESC and C-J willterminate an incremental search.keymap (emacs)Set the current readline keymap. The set of legal keymap names is emacs, emacs-standard, emacs-meta,emacs-ctlx, vi, vi-move, vi-command, and vi-insert. vi is equivalent to vi-command; emacs is equiva‐lent to emacs-standard. The default value is emacs. The value of editing-mode also affects thedefault keymap.emacs-mode-string (@)This string is displayed immediately before the last line of the primary prompt when emacs editing modeis active. The value is expanded like a key binding, so the standard set of meta- and control prefixesand backslash escape sequences is available. Use the \1 and \2 escapes to begin and end sequences ofnon-printing characters, which can be used to embed a terminal control sequence into the mode string.keyseq-timeout (500)Specifies the duration readline will wait for a character when reading an ambiguous key sequence (onethat can form a complete key sequence using the input read so far, or can take additional input to com‐plete a longer key sequence). If no input is received within the timeout, readline will use theshorter but complete key sequence. The value is specified in milliseconds, so a value of 1000 meansthat readline will wait one second for additional input. If this variable is set to a value less thanor equal to zero, or to a non-numeric value, readline will wait until another key is pressed to decidewhich key sequence to complete.mark-directories (On)If set to On, completed directory names have a slash appended.mark-modified-lines (Off)If set to On, history lines that have been modified are displayed with a preceding asterisk (*).mark-symlinked-directories (Off)If set to On, completed names which are symbolic links to directories have a slash appended (subject tothe value of mark-directories).match-hidden-files (On)This variable, when set to On, causes readline to match files whose names begin with a `.' (hiddenfiles) when performing filename completion. If set to Off, the leading `.' must be supplied by theuser in the filename to be completed.menu-complete-display-prefix (Off)If set to On, menu completion displays the common prefix of the list of possible completions (which maybe empty) before cycling through the list.output-meta (Off)If set to On, readline will display characters with the eighth bit set directly rather than as a meta-prefixed escape sequence. The default is Off, but readline will set it to On if the locale containseight-bit characters.page-completions (On)If set to On, readline uses an internal more-like pager to display a screenful of possible completionsat a time.print-completions-horizontally (Off)If set to On, readline will display completions with matches sorted horizontally in alphabetical order,rather than down the screen.revert-all-at-newline (Off)If set to On, readline will undo all changes to history lines before returning when accept-line is exe‐cuted. By default, history lines may be modified and retain individual undo lists across calls toreadline.show-all-if-ambiguous (Off)This alters the default behavior of the completion functions. If set to On, words which have more thanone possible completion cause the matches to be listed immediately instead of ringing the bell.show-all-if-unmodified (Off)This alters the default behavior of the completion functions in a fashion similar toshow-all-if-ambiguous. If set to On, words which have more than one possible completion without anypossible partial completion (the possible completions don't share a common prefix) cause the matches tobe listed immediately instead of ringing the bell.show-mode-in-prompt (Off)If set to On, add a character to the beginning of the prompt indicating the editing mode: emacs, vicommand, or vi insertion. The mode strings are user-settable.skip-completed-text (Off)If set to On, this alters the default completion behavior when inserting a single match into the line.It's only active when performing completion in the middle of a word. If enabled, readline does notinsert characters from the completion that match characters after point in the word being completed, soportions of the word following the cursor are not duplicated.vi-cmd-mode-string ((cmd))This string is displayed immediately before the last line of the primary prompt when vi editing mode isactive and in command mode. The value is expanded like a key binding, so the standard set of meta- andcontrol prefixes and backslash escape sequences is available. Use the \1 and \2 escapes to begin andend sequences of non-printing characters, which can be used to embed a terminal control sequence intothe mode string.vi-ins-mode-string ((ins))This string is displayed immediately before the last line of the primary prompt when vi editing mode isactive and in insertion mode. The value is expanded like a key binding, so the standard set of meta-and control prefixes and backslash escape sequences is available. Use the \1 and \2 escapes to beginand end sequences of non-printing characters, which can be used to embed a terminal control sequenceinto the mode string.visible-stats (Off)If set to On, a character denoting a file's type as reported by stat(2) is appended to the filenamewhen listing possible completions.Conditional ConstructsReadline implements a facility similar in spirit to the conditional compilation features of the C preprocessorwhich allows key bindings and variable settings to be performed as the result of tests. There are four parserdirectives used.$if The $if construct allows bindings to be made based on the editing mode, the terminal being used, or theapplication using readline. The text of the test extends to the end of the line; no characters arerequired to isolate it.mode The mode= form of the $if directive is used to test whether readline is in emacs or vi mode.This may be used in conjunction with the set keymap command, for instance, to set bindings inthe emacs-standard and emacs-ctlx keymaps only if readline is starting out in emacs mode.term The term= form may be used to include terminal-specific key bindings, perhaps to bind the keysequences output by the terminal's function keys. The word on the right side of the = is testedagainst the full name of the terminal and the portion of the terminal name before the first -.This allows sun to match both sun and sun-cmd, for instance.applicationThe application construct is used to include application-specific settings. Each program usingthe readline library sets the application name, and an initialization file can test for a par‐ticular value. This could be used to bind key sequences to functions useful for a specific pro‐gram. For instance, the following command adds a key sequence that quotes the current or previ‐ous word in bash:$if Bash# Quote the current or previous word"\C-xq": "\eb\"\ef\""$endif$endif This command, as seen in the previous example, terminates an $if command.$else Commands in this branch of the $if directive are executed if the test fails.$includeThis directive takes a single filename as an argument and reads commands and bindings from that file.For example, the following directive would read /etc/inputrc:$include /etc/inputrcSEARCHINGReadline provides commands for searching through the command history for lines containing a specified string.There are two search modes: incremental and non-incremental.Incremental searches begin before the user has finished typing the search string. As each character of thesearch string is typed, readline displays the next entry from the history matching the string typed so far.An incremental search requires only as many characters as needed to find the desired history entry. To searchbackward in the history for a particular string, type C-r. Typing C-s searches forward through the history.The characters present in the value of the isearch-terminators variable are used to terminate an incrementalsearch. If that variable has not been assigned a value the Escape and C-J characters will terminate an incre‐mental search. C-G will abort an incremental search and restore the original line. When the search is termi‐nated, the history entry containing the search string becomes the current line.To find other matching entries in the history list, type C-s or C-r as appropriate. This will search backwardor forward in the history for the next line matching the search string typed so far. Any other key sequencebound to a readline command will terminate the search and execute that command. For instance, a newline willterminate the search and accept the line, thereby executing the command from the history list. A movementcommand will terminate the search, make the last line found the current line, and begin editing.Non-incremental searches read the entire search string before starting to search for matching history lines.The search string may be typed by the user or be part of the contents of the current line.EDITING COMMANDSThe following is a list of the names of the commands and the default key sequences to which they are bound.Command names without an accompanying key sequence are unbound by default.In the following descriptions, point refers to the current cursor position, and mark refers to a cursor posi‐tion saved by the set-mark command. The text between the point and mark is referred to as the region.Commands for Movingbeginning-of-line (C-a)Move to the start of the current line.end-of-line (C-e)Move to the end of the line.forward-char (C-f)Move forward a character.backward-char (C-b)Move back a character.forward-word (M-f)Move forward to the end of the next word. Words are composed of alphanumeric characters (letters anddigits).backward-word (M-b)Move back to the start of the current or previous word. Words are composed of alphanumeric characters(letters and digits).clear-screen (C-l)Clear the screen leaving the current line at the top of the screen. With an argument, refresh the cur‐rent line without clearing the screen.redraw-current-lineRefresh the current line.Commands for Manipulating the Historyaccept-line (Newline, Return)Accept the line regardless of where the cursor is. If this line is non-empty, it may be added to thehistory list for future recall with add_history(). If the line is a modified history line, the historyline is restored to its original state.previous-history (C-p)Fetch the previous command from the history list, moving back in the list.next-history (C-n)Fetch the next command from the history list, moving forward in the list.beginning-of-history (M-<)Move to the first line in the history.end-of-history (M->)Move to the end of the input history, i.e., the line currently being entered.reverse-search-history (C-r)Search backward starting at the current line and moving `up' through the history as necessary. This isan incremental search.forward-search-history (C-s)Search forward starting at the current line and moving `down' through the history as necessary. Thisis an incremental search.non-incremental-reverse-search-history (M-p)Search backward through the history starting at the current line using a non-incremental search for astring supplied by the user.non-incremental-forward-search-history (M-n)Search forward through the history using a non-incremental search for a string supplied by the user.history-search-backwardSearch backward through the history for the string of characters between the start of the current lineand the current cursor position (the point). The search string must match at the beginning of a his‐tory line. This is a non-incremental search.history-search-forwardSearch forward through the history for the string of characters between the start of the current lineand the point. The search string must match at the beginning of a history line. This is a non-incre‐mental search.history-substring-search-backwardSearch backward through the history for the string of characters between the start of the current lineand the current cursor position (the point). The search string may match anywhere in a history line.This is a non-incremental search.history-substring-search-forwardSearch forward through the history for the string of characters between the start of the current lineand the point. The search string may match anywhere in a history line. This is a non-incrementalsearch.yank-nth-arg (M-C-y)Insert the first argument to the previous command (usually the second word on the previous line) atpoint. With an argument n, insert the nth word from the previous command (the words in the previouscommand begin with word 0). A negative argument inserts the nth word from the end of the previous com‐mand. Once the argument n is computed, the argument is extracted as if the "!n" history expansion hadbeen specified.yank-last-arg (M-., M-_)Insert the last argument to the previous command (the last word of the previous history entry). With anumeric argument, behave exactly like yank-nth-arg. Successive calls to yank-last-arg move backthrough the history list, inserting the last word (or the word specified by the argument to the firstcall) of each line in turn. Any numeric argument supplied to these successive calls determines thedirection to move through the history. A negative argument switches the direction through the history(back or forward). The history expansion facilities are used to extract the last argument, as if the"!$" history expansion had been specified.Commands for Changing Textend-of-file (usually C-d)The character indicating end-of-file as set, for example, by ``stty''. If this character is read whenthere are no characters on the line, and point is at the beginning of the line, Readline interprets itas the end of input and returns EOF.delete-char (C-d)Delete the character at point. If this function is bound to the same character as the tty EOF charac‐ter, as C-d commonly is, see above for the effects.backward-delete-char (Rubout)Delete the character behind the cursor. When given a numeric argument, save the deleted text on thekill ring.forward-backward-delete-charDelete the character under the cursor, unless the cursor is at the end of the line, in which case thecharacter behind the cursor is deleted.quoted-insert (C-q, C-v)Add the next character that you type to the line verbatim. This is how to insert characters like C-q,for example.tab-insert (M-TAB)Insert a tab character.self-insert (a, b, A, 1, !, ...)Insert the character typed.transpose-chars (C-t)Drag the character before point forward over the character at point, moving point forward as well. Ifpoint is at the end of the line, then this transposes the two characters before point. Negative argu‐ments have no effect.transpose-words (M-t)Drag the word before point past the word after point, moving point over that word as well. If point isat the end of the line, this transposes the last two words on the line.upcase-word (M-u)Uppercase the current (or following) word. With a negative argument, uppercase the previous word, butdo not move point.downcase-word (M-l)Lowercase the current (or following) word. With a negative argument, lowercase the previous word, butdo not move point.capitalize-word (M-c)Capitalize the current (or following) word. With a negative argument, capitalize the previous word,but do not move point.overwrite-modeToggle overwrite mode. With an explicit positive numeric argument, switches to overwrite mode. Withan explicit non-positive numeric argument, switches to insert mode. This command affects only emacsmode; vi mode does overwrite differently. Each call to readline() starts in insert mode. In overwritemode, characters bound to self-insert replace the text at point rather than pushing the text to theright. Characters bound to backward-delete-char replace the character before point with a space. Bydefault, this command is unbound.Killing and Yankingkill-line (C-k)Kill the text from point to the end of the line.backward-kill-line (C-x Rubout)Kill backward to the beginning of the line.unix-line-discard (C-u)Kill backward from point to the beginning of the line. The killed text is saved on the kill-ring.kill-whole-lineKill all characters on the current line, no matter where point is.kill-word (M-d)Kill from point the end of the current word, or if between words, to the end of the next word. Wordboundaries are the same as those used by forward-word.backward-kill-word (M-Rubout)Kill the word behind point. Word boundaries are the same as those used by backward-word.unix-word-rubout (C-w)Kill the word behind point, using white space as a word boundary. The killed text is saved on thekill-ring.unix-filename-ruboutKill the word behind point, using white space and the slash character as the word boundaries. Thekilled text is saved on the kill-ring.delete-horizontal-space (M-\)Delete all spaces and tabs around point.kill-regionKill the text between the point and mark (saved cursor position). This text is referred to as theregion.copy-region-as-killCopy the text in the region to the kill buffer.copy-backward-wordCopy the word before point to the kill buffer. The word boundaries are the same as backward-word.copy-forward-wordCopy the word following point to the kill buffer. The word boundaries are the same as forward-word.yank (C-y)Yank the top of the kill ring into the buffer at point.yank-pop (M-y)Rotate the kill ring, and yank the new top. Only works following yank or yank-pop.Numeric Argumentsdigit-argument (M-0, M-1, ..., M--)Add this digit to the argument already accumulating, or start a new argument. M-- starts a negativeargument.universal-argumentThis is another way to specify an argument. If this command is followed by one or more digits, option‐ally with a leading minus sign, those digits define the argument. If the command is followed by dig‐its, executing universal-argument again ends the numeric argument, but is otherwise ignored. As a spe‐cial case, if this command is immediately followed by a character that is neither a digit or minussign, the argument count for the next command is multiplied by four. The argument count is initiallyone, so executing this function the first time makes the argument count four, a second time makes theargument count sixteen, and so on.Completingcomplete (TAB)Attempt to perform completion on the text before point. The actual completion performed is applica‐tion-specific. Bash, for instance, attempts completion treating the text as a variable (if the textbegins with $), username (if the text begins with ~), hostname (if the text begins with @), or command(including aliases and functions) in turn. If none of these produces a match, filename completion isattempted. Gdb, on the other hand, allows completion of program functions and variables, and onlyattempts filename completion under certain circumstances.possible-completions (M-?)List the possible completions of the text before point. When displaying completions, readline sets thenumber of columns used for display to the value of completion-display-width, the value of the environ‐ment variable COLUMNS, or the screen width, in that order.insert-completions (M-*)Insert all completions of the text before point that would have been generated by possible-completions.menu-completeSimilar to complete, but replaces the word to be completed with a single match from the list of possi‐ble completions. Repeated execution of menu-complete steps through the list of possible completions,inserting each match in turn. At the end of the list of completions, the bell is rung (subject to thesetting of bell-style) and the original text is restored. An argument of n moves n positions forwardin the list of matches; a negative argument may be used to move backward through the list. This com‐mand is intended to be bound to TAB, but is unbound by default.menu-complete-backwardIdentical to menu-complete, but moves backward through the list of possible completions, as ifmenu-complete had been given a negative argument. This command is unbound by default.delete-char-or-listDeletes the character under the cursor if not at the beginning or end of the line (like delete-char).If at the end of the line, behaves identically to possible-completions.Keyboard Macrosstart-kbd-macro (C-x ()Begin saving the characters typed into the current keyboard macro.end-kbd-macro (C-x ))Stop saving the characters typed into the current keyboard macro and store the definition.call-last-kbd-macro (C-x e)Re-execute the last keyboard macro defined, by making the characters in the macro appear as if typed atthe keyboard. print-last-kbd-macro () Print the last keyboard macro defined in a format suitable forthe inputrc file.Miscellaneousre-read-init-file (C-x C-r)Read in the contents of the inputrc file, and incorporate any bindings or variable assignments foundthere.abort (C-g)Abort the current editing command and ring the terminal's bell (subject to the setting of bell-style).do-uppercase-version (M-a, M-b, M-x, ...)If the metafied character x is lowercase, run the command that is bound to the corresponding uppercasecharacter.prefix-meta (ESC)Metafy the next character typed. ESC f is equivalent to Meta-f.undo (C-_, C-x C-u)Incremental undo, separately remembered for each line.revert-line (M-r)Undo all changes made to this line. This is like executing the undo command enough times to return theline to its initial state.tilde-expand (M-&)Perform tilde expansion on the current word.set-mark (C-@, M-<space>)Set the mark to the point. If a numeric argument is supplied, the mark is set to that position.exchange-point-and-mark (C-x C-x)Swap the point with the mark. The current cursor position is set to the saved position, and the oldcursor position is saved as the mark.character-search (C-])A character is read and point is moved to the next occurrence of that character. A negative countsearches for previous occurrences.character-search-backward (M-C-])A character is read and point is moved to the previous occurrence of that character. A negative countsearches for subsequent occurrences.skip-csi-sequenceRead enough characters to consume a multi-key sequence such as those defined for keys like Home andEnd. Such sequences begin with a Control Sequence Indicator (CSI), usually ESC-[. If this sequence isbound to "\[", keys producing such sequences will have no effect unless explicitly bound to a readlinecommand, instead of inserting stray characters into the editing buffer. This is unbound by default,but usually bound to ESC-[.insert-comment (M-#)Without a numeric argument, the value of the readline comment-begin variable is inserted at the begin‐ning of the current line. If a numeric argument is supplied, this command acts as a toggle: if thecharacters at the beginning of the line do not match the value of comment-begin, the value is inserted,otherwise the characters in comment-begin are deleted from the beginning of the line. In either case,the line is accepted as if a newline had been typed. The default value of comment-begin makes the cur‐rent line a shell comment. If a numeric argument causes the comment character to be removed, the linewill be executed by the shell.dump-functionsPrint all of the functions and their key bindings to the readline output stream. If a numeric argumentis supplied, the output is formatted in such a way that it can be made part of an inputrc file.dump-variablesPrint all of the settable variables and their values to the readline output stream. If a numeric argu‐ment is supplied, the output is formatted in such a way that it can be made part of an inputrc file.dump-macrosPrint all of the readline key sequences bound to macros and the strings they output. If a numericargument is supplied, the output is formatted in such a way that it can be made part of an inputrcfile.emacs-editing-mode (C-e)When in vi command mode, this causes a switch to emacs editing mode.vi-editing-mode (M-C-j)When in emacs editing mode, this causes a switch to vi editing mode.DEFAULT KEY BINDINGSThe following is a list of the default emacs and vi bindings. Characters with the eighth bit set are writtenas M-<character>, and are referred to as metafied characters. The printable ASCII characters not mentioned inthe list of emacs standard bindings are bound to the self-insert function, which just inserts the given char‐acter into the input line. In vi insertion mode, all characters not specifically mentioned are bound toself-insert. Characters assigned to signal generation by stty(1) or the terminal driver, such as C-Z or C-C,retain that function. Upper and lower case metafied characters are bound to the same function in the emacsmode meta keymap. The remaining characters are unbound, which causes readline to ring the bell (subject tothe setting of the bell-style variable).Emacs ModeEmacs Standard bindings"C-@" set-mark"C-A" beginning-of-line"C-B" backward-char"C-D" delete-char"C-E" end-of-line"C-F" forward-char"C-G" abort"C-H" backward-delete-char"C-I" complete"C-J" accept-line"C-K" kill-line"C-L" clear-screen"C-M" accept-line"C-N" next-history"C-P" previous-history"C-Q" quoted-insert"C-R" reverse-search-history"C-S" forward-search-history"C-T" transpose-chars"C-U" unix-line-discard"C-V" quoted-insert"C-W" unix-word-rubout"C-Y" yank"C-]" character-search"C-_" undo" " to "/" self-insert"0" to "9" self-insert":" to "~" self-insert"C-?" backward-delete-charEmacs Meta bindings"M-C-G" abort"M-C-H" backward-kill-word"M-C-I" tab-insert"M-C-J" vi-editing-mode"M-C-M" vi-editing-mode"M-C-R" revert-line"M-C-Y" yank-nth-arg"M-C-[" complete"M-C-]" character-search-backward"M-space" set-mark"M-#" insert-comment"M-&" tilde-expand"M-*" insert-completions"M--" digit-argument"M-." yank-last-arg"M-0" digit-argument"M-1" digit-argument"M-2" digit-argument"M-3" digit-argument"M-4" digit-argument"M-5" digit-argument"M-6" digit-argument"M-7" digit-argument"M-8" digit-argument"M-9" digit-argument"M-<" beginning-of-history"M-=" possible-completions"M->" end-of-history"M-?" possible-completions"M-B" backward-word"M-C" capitalize-word"M-D" kill-word"M-F" forward-word"M-L" downcase-word"M-N" non-incremental-forward-search-history"M-P" non-incremental-reverse-search-history"M-R" revert-line"M-T" transpose-words"M-U" upcase-word"M-Y" yank-pop"M-\" delete-horizontal-space"M-~" tilde-expand"M-C-?" backward-kill-word"M-_" yank-last-argEmacs Control-X bindings"C-XC-G" abort"C-XC-R" re-read-init-file"C-XC-U" undo"C-XC-X" exchange-point-and-mark"C-X(" start-kbd-macro"C-X)" end-kbd-macro"C-XE" call-last-kbd-macro"C-XC-?" backward-kill-lineVI Mode bindingsVI Insert Mode functions"C-D" vi-eof-maybe"C-H" backward-delete-char"C-I" complete"C-J" accept-line"C-M" accept-line"C-R" reverse-search-history"C-S" forward-search-history"C-T" transpose-chars"C-U" unix-line-discard"C-V" quoted-insert"C-W" unix-word-rubout"C-Y" yank"C-[" vi-movement-mode"C-_" undo" " to "~" self-insert"C-?" backward-delete-charVI Command Mode functions"C-D" vi-eof-maybe"C-E" emacs-editing-mode"C-G" abort"C-H" backward-char"C-J" accept-line"C-K" kill-line"C-L" clear-screen"C-M" accept-line"C-N" next-history"C-P" previous-history"C-Q" quoted-insert"C-R" reverse-search-history"C-S" forward-search-history"C-T" transpose-chars"C-U" unix-line-discard"C-V" quoted-insert"C-W" unix-word-rubout"C-Y" yank"C-_" vi-undo" " forward-char"#" insert-comment"$" end-of-line"%" vi-match"&" vi-tilde-expand"*" vi-complete"+" next-history"," vi-char-search
