+Introduction to Line Editing
+============================
+
+ The following paragraphs describe the notation used to represent
+keystrokes.
+
+ The text <C-k> is read as `Control-K' and describes the character
+produced when the <k> key is pressed while the Control key is depressed.
+
+ The text <M-k> is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the <k>
+key is pressed. The Meta key is labeled <ALT> on many keyboards. On
+keyboards with two keys labeled <ALT> (usually to either side of the
+space bar), the <ALT> on the left side is generally set to work as a
+Meta key. The <ALT> key on the right may also be configured to work as
+a Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+ If you do not have a Meta or <ALT> key, or another key working as a
+Meta key, the identical keystroke can be generated by typing <ESC>
+first, and then typing <k>. Either process is known as "metafying" the
+<k> key.
+
+ The text <M-C-k> is read as `Meta-Control-k' and describes the
+character produced by "metafying" <C-k>.
+
+ In addition, several keys have their own names. Specifically,
+<DEL>, <ESC>, <LFD>, <SPC>, <RET>, and <TAB> all stand for themselves
+when seen in this text, or in an init file (*note Readline Init
+File::.). If your keyboard lacks a <LFD> key, typing <C-j> will
+produce the desired character. The <RET> key may be labeled <Return>
+or <Enter> on some keyboards.

+
+Readline Interaction
+====================
+
+ Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled. The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line. Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections. Then, when you are satisfied with
+the line, you simply press <RETURN>. You do not have to be at the end
+of the line to press <RETURN>; the entire line is accepted regardless
+of the location of the cursor within the line.

+
+Readline Bare Essentials
+------------------------
+
+ In order to enter characters into the line, simply type them. The
+typed character appears where the cursor was, and then the cursor moves
+one space to the right. If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+ Sometimes you may mistype a character, and not notice the error
+until you have typed several other characters. In that case, you can
+type <C-b> to move the cursor to the left, and then correct your
+mistake. Afterwards, you can move the cursor to the right with <C-f>.
+
+ When you add text in the middle of a line, you will notice that
+characters to the right of the cursor are `pushed over' to make room
+for the text that you have inserted. Likewise, when you delete text
+behind the cursor, characters to the right of the cursor are `pulled
+back' to fill in the blank space created by the removal of the text. A
+list of the bare essentials for editing the text of an input line
+follows.
+
+<C-b>
+ Move back one character.
+
+<C-f>
+ Move forward one character.
+
+<DEL> or <Backspace>
+ Delete the character to the left of the cursor.
+
+<C-d>
+ Delete the character underneath the cursor.
+
+Printing characters
+ Insert the character into the line at the cursor.
+
+<C-_> or <C-x C-u>
+ Undo the last editing command. You can undo all the way back to an
+ empty line.
+
+(Depending on your configuration, the <Backspace> key be set to delete
+the character to the left of the cursor and the <DEL> key set to delete
+the character underneath the cursor, like <C-d>, rather than the
+character to the left of the cursor.)

+
+Readline Movement Commands
+--------------------------
+
+ The above table describes the most basic keystrokes that you need in
+order to do editing of the input line. For your convenience, many
+other commands have been added in addition to <C-b>, <C-f>, <C-d>, and
+<DEL>. Here are some commands for moving more rapidly about the line.
+
+<C-a>
+ Move to the start of the line.
+
+<C-e>
+ Move to the end of the line.
+
+<M-f>
+ Move forward a word, where a word is composed of letters and
+ digits.
+
+<M-b>
+ Move backward a word.
+
+<C-l>
+ Clear the screen, reprinting the current line at the top.
+
+ Notice how <C-f> moves forward a character, while <M-f> moves
+forward a word. It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.
+
+
+File: rluserman.info, Node: Readline Killing Commands, Next: Readline Arguments, Prev: Readline Movement Commands, Up: Readline Interaction
+
+Readline Killing Commands
+-------------------------
+
+ "Killing" text means to delete the text from the line, but to save
+it away for later use, usually by "yanking" (re-inserting) it back into
+the line. (`Cut' and `paste' are more recent jargon for `kill' and
+`yank'.)
+
+ If the description for a command says that it `kills' text, then you
+can be sure that you can get the text back in a different (or the same)
+place later.
+
+ When you use a kill command, the text is saved in a "kill-ring".
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all. The kill ring is not line
+specific; the text that you killed on a previously typed line is
+available to be yanked back later, when you are typing another line.
+
+ Here is the list of commands for killing text.
+
+<C-k>
+ Kill the text from the current cursor position to the end of the
+ line.
+
+<M-d>
+ Kill from the cursor to the end of the current word, or, if between
+ words, to the end of the next word. Word boundaries are the same
+ as those used by <M-f>.
+
+<M-DEL>
+ Kill from the cursor the start of the previous word, or, if between
+ words, to the start of the previous word. Word boundaries are the
+ same as those used by <M-b>.
+
+<C-w>
+ Kill from the cursor to the previous whitespace. This is
+ different than <M-DEL> because the word boundaries differ.
+
+ Here is how to "yank" the text back into the line. Yanking means to
+copy the most-recently-killed text from the kill buffer.
+
+<C-y>
+ Yank the most recently killed text back into the buffer at the
+ cursor.
+
+<M-y>
+ Rotate the kill-ring, and yank the new top. You can only do this
+ if the prior command is <C-y> or <M-y>.
+
+
+File: rluserman.info, Node: Readline Arguments, Next: Searching, Prev: Readline Killing Commands, Up: Readline Interaction
+
+Readline Arguments
+------------------
+
+ You can pass numeric arguments to Readline commands. Sometimes the
+argument acts as a repeat count, other times it is the sign of the
+argument that is significant. If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction. For example, to kill text back to the
+start of the line, you might type `M-- C-k'.
+
+ The general way to pass numeric arguments to a command is to type
+meta digits before the command. If the first `digit' typed is a minus
+sign (`-'), then the sign of the argument will be negative. Once you
+have typed one meta digit to get the argument started, you can type the
+remainder of the digits, and then the command. For example, to give
+the <C-d> command an argument of 10, you could type `M-1 0 C-d'.
+
+
+File: rluserman.info, Node: Searching, Prev: Readline Arguments, Up: Readline Interaction
+
+Searching for Commands in the History
+-------------------------------------
+
+ Readline 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 the search 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 search backward 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 incremental
+search. If that variable has not been assigned a value, the <ESC> and
+<C-J> characters will terminate an incremental search. <C-g> will
+abort an incremental search and restore the original line. When the
+search is terminated, the history entry containing the search string
+becomes the current line.
+
+ To find other matching entries in the history list, type <C-r> or
+<C-s> as appropriate. This will search backward or forward in the
+history for the next entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate the
+search and execute that command. For instance, a <RET> will terminate
+the search and accept the line, thereby executing the command from the
+history list.
+
+ 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.

+
+Readline Init File
+==================
+
+ Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings. Any user can customize programs that use Readline by
+putting commands in an "inputrc" file, conventionally in his home
+directory. The name of this file is taken from the value of the
+environment variable `INPUTRC'. If that variable is unset, the default
+is `~/.inputrc'.
+
+ When a program which uses the Readline library starts up, the init
+file is read, and the key bindings are set.
+
+ In addition, the `C-x C-r' command re-reads this init file, thus
+incorporating any changes that you might have made to it.

+
+
+File: rluserman.info, Node: Readline Init File Syntax, Next: Conditional Init Constructs, Up: Readline Init File
+
+Readline Init File Syntax
+-------------------------
+
+ There are only a few basic constructs allowed in the Readline init
+file. Blank lines are ignored. Lines beginning with a `#' are
+comments. Lines beginning with a `$' indicate conditional constructs
+(*note Conditional Init Constructs::.). Other lines denote variable
+settings and key bindings.
+
+Variable Settings
+ You can modify the run-time behavior of Readline by altering the
+ values of variables in Readline using the `set' command within the
+ init file. Here is how to change from the default Emacs-like key
+ binding to use `vi' line editing commands:
+
+ set editing-mode vi
+
+ A great deal of run-time behavior is changeable with the following
+ variables.
+
+ `bell-style'
+ Controls what happens when Readline wants to ring the
+ terminal bell. If set to `none', Readline never rings the
+ bell. If set to `visible', Readline uses a visible bell if
+ one is available. If set to `audible' (the default),
+ Readline attempts to ring the terminal's bell.
+
+ `comment-begin'
+ The string to insert at the beginning of the line when the
+ `insert-comment' command is executed. The default value is
+ `"#"'.
+
+ `completion-ignore-case'
+ If set to `on', Readline performs filename matching and
+ completion in a case-insensitive fashion. The default value
+ is `off'.
+
+ `completion-query-items'
+ The number of possible completions that determines when the
+ user is asked whether he wants to see the list of
+ possibilities. If the number of possible completions is
+ greater than this value, Readline will ask the user whether
+ or not he wishes to view them; otherwise, they are simply
+ listed. The default limit is `100'.
+
+ `convert-meta'
+ If set to `on', Readline will convert characters with the
+ eighth bit set to an ASCII key sequence by stripping the
+ eighth bit and prefixing an <ESC> character, converting them
+ to a meta-prefixed key sequence. The default value is `on'.
+
+ `disable-completion'
+ If set to `On', Readline will inhibit word completion.
+ Completion characters will be inserted into the line as if
+ they had been mapped to `self-insert'. The default is `off'.
+
+ `editing-mode'
+ The `editing-mode' variable controls which default set of key
+ bindings is used. By default, Readline starts up in Emacs
+ editing mode, where the keystrokes are most similar to Emacs.
+ This variable can be set to either `emacs' or `vi'.
+
+ `enable-keypad'
+ When set to `on', Readline will try to enable the application
+ keypad when it is called. Some systems need this to enable
+ the arrow keys. The default is `off'.
+
+ `expand-tilde'
+ If set to `on', tilde expansion is performed when Readline
+ attempts word completion. The default is `off'.
+
+ `horizontal-scroll-mode'
+ This variable can be set to either `on' or `off'. Setting it
+ to `on' means that the text of the lines being edited will
+ scroll horizontally on a single screen line when they are
+ longer than the width of the screen, instead of wrapping onto
+ a new screen line. By default, this variable is set to `off'.
+
+ `input-meta'
+ If set to `on', Readline will enable eight-bit input (it will
+ not strip the eighth bit from the characters it reads),
+ regardless of what the terminal claims it can support. The
+ default value is `off'. The name `meta-flag' is a synonym
+ for this variable.
+
+ `isearch-terminators'
+ The string of characters that should terminate an incremental
+ search without subsequently executing the character as a
+ command (*note Searching::.). If this variable has not been
+ given a value, the characters <ESC> and <C-J> will terminate
+ an incremental search.
+
+ `keymap'
+ Sets Readline's idea of the current keymap for key binding
+ commands. Acceptable `keymap' names are `emacs',
+ `emacs-standard', `emacs-meta', `emacs-ctlx', `vi',
+ `vi-command', and `vi-insert'. `vi' is equivalent to
+ `vi-command'; `emacs' is equivalent to `emacs-standard'. The
+ default value is `emacs'. The value of the `editing-mode'
+ variable also affects the default keymap.
+
+ `mark-directories'
+ If set to `on', completed directory names have a slash
+ appended. The default is `on'.
+
+ `mark-modified-lines'
+ This variable, when set to `on', causes Readline to display an
+ asterisk (`*') at the start of history lines which have been
+ modified. This variable is `off' by default.
+
+ `output-meta'
+ 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'.
+
+ `print-completions-horizontally'
+ If set to `on', Readline will display completions with matches
+ sorted horizontally in alphabetical order, rather than down
+ the screen. The default is `off'.
+
+ `show-all-if-ambiguous'
+ This alters the default behavior of the completion functions.
+ If set to `on', words which have more than one possible
+ completion cause the matches to be listed immediately instead
+ of ringing the bell. The default value is `off'.
+
+ `visible-stats'
+ If set to `on', a character denoting a file's type is
+ appended to the filename when listing possible completions.
+ The default is `off'.
+
+Key Bindings
+ The syntax for controlling key bindings in the init file is
+ simple. First you need to find the name of the command that you
+ want to change. The following sections contain tables of the
+ command name, the default keybinding, if any, and a short
+ description of what the command does.
+
+ Once you know the name of the command, simply place the name of
+ the key you wish to bind the command to, a colon, and then the
+ name of the command on a line in the init file. The name of the
+ key can be expressed in different ways, depending on which is most
+ comfortable for you.
+
+ KEYNAME: FUNCTION-NAME or MACRO
+ KEYNAME is the name of a key spelled out in English. For
+ example:
+ Control-u: universal-argument
+ Meta-Rubout: backward-kill-word
+ Control-o: "> output"
+
+ In the above example, <C-u> is bound to the function
+ `universal-argument', and <C-o> is bound to run the macro
+ expressed on the right hand side (that is, to insert the text
+ `> output' into the line).
+
+ "KEYSEQ": FUNCTION-NAME or MACRO
+ KEYSEQ differs from KEYNAME above in that strings denoting an
+ entire key sequence can be specified, by placing the key
+ sequence in double quotes. Some GNU Emacs style key escapes
+ can be used, as in the following example, but the special
+ character names are not recognized.
+
+ "\C-u": universal-argument
+ "\C-x\C-r": re-read-init-file
+ "\e[11~": "Function Key 1"
+
+ In the above example, <C-u> is bound to the function
+ `universal-argument' (just as it was in the first example),
+ `<C-x> <C-r>' is bound to the function `re-read-init-file',
+ and `<ESC> <[> <1> <1> <~>' is bound to insert the text
+ `Function Key 1'.
+
+ The following GNU Emacs style escape sequences are available when
+ specifying key sequences:
+
+ `\C-'
+ control prefix
+
+ `\M-'
+ meta prefix
+
+ `\e'
+ an escape character
+
+ `\\'
+ backslash
+
+ `\"'
+ <">, a double quotation mark
+
+ `\''
+ <'>, a single quote or apostrophe
+
+ In 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 character whose `ASCII' code is the octal value NNN (one
+ to three digits)
+
+ `\xNNN'
+ the character whose `ASCII' code is the hexadecimal value NNN
+ (one to three digits)
+
+ When entering the text of a macro, single or double quotes must 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 are expanded. Backslash will quote any other
+ character in the macro text, including `"' and `''. For example,
+ the following binding will make `C-x \' insert a single `\' into
+ the line:
+ "\C-x\\": "\\"
+
+

+
+Conditional Init Constructs
+---------------------------
+
+ Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key bindings
+and variable settings to be performed as the result of tests. There
+are four parser directives used.
+
+`$if'
+ The `$if' construct allows bindings to be made based on the
+ editing mode, the terminal being used, or the application using
+ Readline. The text of the test extends to the end of the line; no
+ characters are required 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 in the `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 key sequences output by the
+ terminal's function keys. The word on the right side of the
+ `=' is tested against both 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.
+
+ `application'
+ The APPLICATION construct is used to include
+ application-specific settings. Each program using the
+ Readline library sets the APPLICATION NAME, and you can test
+ for it. This could be used to bind key sequences to
+ functions useful for a specific program. For instance, the
+ following command adds a key sequence that quotes the current
+ or previous 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 `$if' directive are executed if the
+ test fails.
+
+`$include'
+ This directive takes a single filename as an argument and reads
+ commands and bindings from that file.
+ $include /etc/inputrc

+`redraw-current-line ()'
+ Refresh the current line. By default, this is unbound.
+
+
+File: rluserman.info, Node: Commands For History, Next: Commands For Text, Prev: Commands For Moving, Up: Bindable Readline Commands
+
+Commands For Manipulating The History
+-------------------------------------
+
+`accept-line (Newline, Return)'
+ Accept the line regardless of where the cursor is. If this line is
+ non-empty, add it to the history list. If this line was a history
+ line, then restore the history line to its original state.
+
+`previous-history (C-p)'
+ Move `up' through the history list.
+
+`next-history (C-n)'
+ Move `down' through the history 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 is an incremental search.
+
+`forward-search-history (C-s)'
+ Search forward starting at the current line and moving `down'
+ through the the history as necessary. This is an incremental
+ search.
+
+`non-incremental-reverse-search-history (M-p)'
+ Search backward starting at the current line and moving `up'
+ through the history as necessary using a non-incremental search
+ for a string supplied by the user.
+
+`non-incremental-forward-search-history (M-n)'
+ Search forward starting at the current line and moving `down'
+ through the the history as necessary using a non-incremental search
+ for a string supplied by the user.
+
+`history-search-forward ()'
+ Search forward through the history for the string of characters
+ between the start of the current line and the point. This is a
+ non-incremental search. By default, this command is unbound.
+
+`history-search-backward ()'
+ Search backward through the history for the string of characters
+ between the start of the current line and the point. This is a
+ non-incremental search. By default, this command is unbound.
+
+`yank-nth-arg (M-C-y)'
+ Insert the first argument to the previous command (usually the
+ second word on the previous line). With an argument N, insert the
+ Nth word from the previous command (the words in the previous
+ command begin with word 0). A negative argument inserts the Nth
+ word from the end of the previous command.
+
+`yank-last-arg (M-., M-_)'
+ Insert last argument to the previous command (the last word of the
+ previous history entry). With an argument, behave exactly like
+ `yank-nth-arg'. Successive calls to `yank-last-arg' move back
+ through the history list, inserting the last argument of each line
+ in turn.
+

+
+Commands For Changing Text
+--------------------------
+
+`delete-char (C-d)'
+ Delete the character under the cursor. If the cursor is at the
+ beginning of the line, there are no characters in the line, and
+ the last character typed was not bound to `delete-char', then
+ return `EOF'.
+
+`backward-delete-char (Rubout)'
+ Delete the character behind the cursor. A numeric argument means
+ to kill the characters instead of deleting them.
+
+`forward-backward-delete-char ()'
+ Delete the character under the cursor, unless the cursor is at the
+ end of the line, in which case the character behind the cursor is
+ deleted. By default, this is not bound to a key.
+
+`quoted-insert (C-q, C-v)'
+ Add the next character typed to the line verbatim. This is how to
+ insert key sequences like <C-q>, for example.
+
+`tab-insert (M-TAB)'
+ Insert a tab character.
+
+`self-insert (a, b, A, 1, !, ...)'
+ Insert yourself.
+
+`transpose-chars (C-t)'
+ Drag the character before the cursor forward over the character at
+ the cursor, moving the cursor forward as well. If the insertion
+ point is at the end of the line, then this transposes the last two
+ characters of the line. Negative arguments have no effect.
+
+`transpose-words (M-t)'
+ Drag the word before point past the word after point, moving point
+ past that word as well.
+
+`upcase-word (M-u)'
+ Uppercase the current (or following) word. With a negative
+ argument, uppercase the previous word, but do not move the cursor.
+
+`downcase-word (M-l)'
+ Lowercase the current (or following) word. With a negative
+ argument, lowercase the previous word, but do not move the cursor.
+
+`capitalize-word (M-c)'
+ Capitalize the current (or following) word. With a negative
+ argument, capitalize the previous word, but do not move the cursor.
+
+
+File: rluserman.info, Node: Commands For Killing, Next: Numeric Arguments, Prev: Commands For Text, Up: Bindable Readline Commands
+
+Killing And Yanking
+-------------------
+
+`kill-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 the cursor to the beginning of the current line.
+
+`kill-whole-line ()'
+ Kill all characters on the current line, no matter point is. By
+ default, this is unbound.
+
+`kill-word (M-d)'
+ Kill from point to the end of the current word, or if between
+ words, to the end of the next word. Word boundaries are the same
+ as `forward-word'.
+
+`backward-kill-word (M-DEL)'
+ Kill the word behind point. Word boundaries are the same as
+ `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 the kill-ring.
+
+`delete-horizontal-space ()'
+ Delete all spaces and tabs around point. By default, this is
+ unbound.
+
+`kill-region ()'
+ Kill the text in the current region. By default, this command is
+ unbound.
+
+`copy-region-as-kill ()'
+ Copy the text in the region to the kill buffer, so it can be yanked
+ right away. By default, this command is unbound.
+
+`copy-backward-word ()'
+ Copy the word before point to the kill buffer. The word
+ boundaries are the same as `backward-word'. By default, this
+ command is unbound.
+
+`copy-forward-word ()'
+ Copy the word following point to the kill buffer. The word
+ boundaries are the same as `forward-word'. By default, this
+ command is unbound.
+
+`yank (C-y)'
+ Yank the top of the kill ring into the buffer at the current
+ cursor position.
+
+`yank-pop (M-y)'
+ Rotate the kill-ring, and yank the new top. You can only do this
+ if the prior command is yank or yank-pop.
+
+
+File: rluserman.info, Node: Numeric Arguments, Next: Commands For Completion, Prev: Commands For Killing, Up: Bindable Readline Commands
+
+Specifying Numeric Arguments
+----------------------------
+
+`digit-argument (M-0, M-1, ... M--)'
+ Add this digit to the argument already accumulating, or start a new
+ argument. <M-> starts a negative argument.
+
+`universal-argument ()'
+ This is another way to specify an argument. If this command is
+ followed by one or more digits, optionally with a leading minus
+ sign, those digits define the argument. If the command is
+ followed by digits, executing `universal-argument' again ends the
+ numeric argument, but is otherwise ignored. As a special case, if
+ this command is immediately followed by a character that is
+ neither a digit or minus sign, the argument count for the next
+ command is multiplied by four. The argument count is initially
+ one, so executing this function the first time makes the argument
+ count four, a second time makes the argument count sixteen, and so
+ on. By default, this is not bound to a key.
+
+
+File: rluserman.info, Node: Commands For Completion, Next: Keyboard Macros, Prev: Numeric Arguments, Up: Bindable Readline Commands
+
+Letting Readline Type For You
+-----------------------------
+
+`complete (TAB)'
+ Attempt to do completion on the text before the cursor. This is
+ application-specific. Generally, if you are typing a filename
+ argument, you can do filename completion; if you are typing a
+ command, you can do command completion; if you are typing in a
+ symbol to GDB, you can do symbol name completion; if you are
+ typing in a variable to Bash, you can do variable name completion,
+ and so on.
+
+`possible-completions (M-?)'
+ List the possible completions of the text before the cursor.
+
+`insert-completions (M-*)'
+ Insert all completions of the text before point that would have
+ been generated by `possible-completions'.
+
+`menu-complete ()'
+ Similar to `complete', but replaces the word to be completed with
+ a single match from the list of possible 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 and the original text is restored.
+ An argument of N moves N positions forward in the list of matches;
+ a negative argument may be used to move backward through the list.
+ This command is intended to be bound to `TAB', but is unbound by
+ default.
+
+`delete-char-or-list ()'
+ Deletes 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'. This command is
+ unbound by default.
+
+
+File: rluserman.info, Node: Keyboard Macros, Next: Miscellaneous Commands, Prev: Commands For Completion, Up: Bindable Readline Commands
+
+Keyboard Macros
+---------------
+
+`start-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 save 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 at the keyboard.
+
+
+File: rluserman.info, Node: Miscellaneous Commands, Prev: Keyboard Macros, Up: Bindable Readline Commands
+
+Some Miscellaneous Commands
+---------------------------
+
+`re-read-init-file (C-x C-r)'
+ Read in the contents of the INPUTRC file, and incorporate any
+ bindings or variable assignments found there.
+
+`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 uppercase character.
+
+`prefix-meta (ESC)'
+ Make the next character typed be metafied. This is for keyboards
+ without a meta key. Typing `ESC f' is equivalent to typing `M-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 get back to the beginning.
+
+`tilde-expand (M-~)'
+ Perform tilde expansion on the current word.
+
+`set-mark (C-@)'
+ Set the mark to the current 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 old cursor 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 count searches 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 count searches for subsequent
+ occurrences.
+
+`insert-comment (M-#)'
+ The value of the `comment-begin' variable is inserted at the
+ beginning of the current line, and the line is accepted as if a
+ newline had been typed.
+
+`dump-functions ()'
+ Print all of the functions and their key bindings to the Readline
+ output stream. If a numeric argument is supplied, the output is
+ formatted in such a way that it can be made part of an INPUTRC
+ file. This command is unbound by default.
+
+`dump-variables ()'
+ Print all of the settable variables and their values to the
+ Readline output stream. If a numeric argument is supplied, the
+ output is formatted in such a way that it can be made part of an
+ INPUTRC file. This command is unbound by default.
+
+`dump-macros ()'
+ Print all of the Readline key sequences bound to macros and the
+ strings they ouput. If a numeric argument is supplied, the output
+ is formatted in such a way that it can be made part of an INPUTRC
+ file. This command is unbound by default.

+
+Readline vi Mode
+================
+
+ While the Readline library does not have a full set of `vi' editing
+functions, it does contain enough to allow simple editing of the line.
+The Readline `vi' mode behaves as specified in the POSIX 1003.2
+standard.
+
+ In order to switch interactively between `emacs' and `vi' editing
+modes, use the command M-C-j (toggle-editing-mode). The Readline
+default is `emacs' mode.
+
+ When you enter a line in `vi' mode, you are already placed in
+`insertion' mode, as if you had typed an `i'. Pressing <ESC> switches
+you into `command' mode, where you can edit the text of the line with
+the standard `vi' movement keys, move to previous history lines with
+`k' and subsequent lines with `j', and so forth.
