@node Commands For Killing
@subsection Killing And Yanking

@ftable @code

@item kill-line (C-k)
Kill the text from point to the end of the line.

@item backward-kill-line (C-x Rubout)
Kill backward to the beginning of the line.

@item unix-line-discard (C-u)
Kill backward from the cursor to the beginning of the current line.

@item kill-whole-line ()
Kill all characters on the current line, no matter where point is.
By default, this is unbound.

@item 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 @code{forward-word}.

@item backward-kill-word (M-@key{DEL})
Kill the word behind point.
Word boundaries are the same as @code{backward-word}.

@item 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.

@item delete-horizontal-space ()
Delete all spaces and tabs around point.  By default, this is unbound.

@item kill-region ()
Kill the text in the current region.
By default, this command is unbound.

@item 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.

@item copy-backward-word ()
Copy the word before point to the kill buffer.
The word boundaries are the same as @code{backward-word}.
By default, this command is unbound.

@item copy-forward-word ()
Copy the word following point to the kill buffer.
The word boundaries are the same as @code{forward-word}.
By default, this command is unbound.

@item yank (C-y)
Yank the top of the kill ring into the buffer at point.

@item yank-pop (M-y)
Rotate the kill-ring, and yank the new top.  You can only do this if
the prior command is @code{yank} or @code{yank-pop}.
@end ftable

@node Numeric Arguments
@subsection Specifying Numeric Arguments
@ftable @code

@item digit-argument (@kbd{M-0}, @kbd{M-1}, @dots{} @kbd{M--})
Add this digit to the argument already accumulating, or start a new
argument.  @kbd{M--} starts a negative argument.

@item 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 @code{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.
@end ftable

@node Commands For Completion
@subsection Letting Readline Type For You

@ftable @code
@item complete (@key{TAB})
Attempt to perform completion on the text before point.
The actual completion performed is application-specific.
@ifset BashFeatures
Bash attempts completion treating the text as a variable (if the
text begins with @samp{$}), username (if the text begins with
@samp{~}), hostname (if the text begins with @samp{@@}), or
command (including aliases and functions) in turn.  If none 
of these produces a match, filename completion is attempted.
@end ifset
@ifclear BashFeatures
The default is filename completion.
@end ifclear

@item possible-completions (M-?)
List the possible completions of the text before point.

@item insert-completions (M-*)
Insert all completions of the text before point that would have
been generated by @code{possible-completions}.

@item menu-complete ()
Similar to @code{complete}, but replaces the word to be completed
with a single match from the list of possible completions.
Repeated execution of @code{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 the setting of @code{bell-style})
and the original text is restored.
An argument of @var{n} moves @var{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 @key{TAB}, but is unbound
by default.

@item delete-char-or-list ()
Deletes the character under the cursor if not at the beginning or
end of the line (like @code{delete-char}).
If at the end of the line, behaves identically to
@code{possible-completions}.
This command is unbound by default.

@ifset BashFeatures
@item complete-filename (M-/)
Attempt filename completion on the text before point.

@item possible-filename-completions (C-x /)
List the possible completions of the text before point,
treating it as a filename.

@item complete-username (M-~)
Attempt completion on the text before point, treating
it as a username.

@item possible-username-completions (C-x ~)
List the possible completions of the text before point,
treating it as a username.

@item complete-variable (M-$)
Attempt completion on the text before point, treating
it as a shell variable.

@item possible-variable-completions (C-x $)
List the possible completions of the text before point,
treating it as a shell variable.

@item complete-hostname (M-@@)
Attempt completion on the text before point, treating
it as a hostname.

@item possible-hostname-completions (C-x @@)
List the possible completions of the text before point,
treating it as a hostname.

@item complete-command (M-!)
Attempt completion on the text before point, treating
it as a command name.  Command completion attempts to
match the text against aliases, reserved words, shell
functions, shell builtins, and finally executable filenames,
in that order.

@item possible-command-completions (C-x !)
List the possible completions of the text before point,
treating it as a command name.

@item dynamic-complete-history (M-@key{TAB})
Attempt completion on the text before point, comparing
the text against lines from the history list for possible
completion matches.

@item complete-into-braces (M-@{)
Perform filename completion and insert the list of possible completions
enclosed within braces so the list is available to the shell
(@pxref{Brace Expansion}).

@end ifset
@end ftable

@node Keyboard Macros
@subsection Keyboard Macros
@ftable @code

@item start-kbd-macro (C-x ()
Begin saving the characters typed into the current keyboard macro.

@item end-kbd-macro (C-x ))
Stop saving the characters typed into the current keyboard macro
and save the definition.

@item 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.

@end ftable

@node Miscellaneous Commands
@subsection Some Miscellaneous Commands
@ftable @code

@item re-read-init-file (C-x C-r)
Read in the contents of the @var{inputrc} file, and incorporate
any bindings or variable assignments found there.

@item abort (C-g)
Abort the current editing command and
ring the terminal's bell (subject to the setting of
@code{bell-style}).

@item do-uppercase-version (M-a, M-b, M-@var{x}, @dots{})
If the metafied character @var{x} is lowercase, run the command
that is bound to the corresponding uppercase character.

@item prefix-meta (@key{ESC})
Metafy the next character typed.  This is for keyboards
without a meta key.  Typing @samp{@key{ESC} f} is equivalent to typing
@kbd{M-f}.

@item undo (C-_ or C-x C-u)
Incremental undo, separately remembered for each line.

@item revert-line (M-r)
Undo all changes made to this line.  This is like executing the @code{undo}
command enough times to get back to the beginning.

@ifset BashFeatures
@item tilde-expand (M-&)
@end ifset
@ifclear BashFeatures
@item tilde-expand (M-~)
@end ifclear
Perform tilde expansion on the current word.

@item set-mark (C-@@)
Set the mark to the point.  If a
numeric argument is supplied, the mark is set to that position.

@item 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.

@item 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.

@item 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.

@item insert-comment (M-#)
Without a numeric argument, the value of the @code{comment-begin}
variable is inserted at the beginning of the current line.
If a numeric argument is supplied, this command acts as a toggle:  if
the characters at the beginning of the line do not match the value
of @code{comment-begin}, the value is inserted, otherwise
the characters in @code{comment-begin} are deleted from the beginning of
the line.
In either case, the line is accepted as if a newline had been typed.
@ifset BashFeatures
The default value of @code{comment-begin} causes this command
to make the current line a shell comment.
If a numeric argument causes the comment character to be removed, the line
will be executed by the shell.
@end ifset

@item 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 @var{inputrc} file.  This command is unbound by default.

@item 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 @var{inputrc} file.  This command is unbound by default.

@item dump-macros ()
Print all of the Readline key sequences bound to macros and the
strings they output.  If a numeric argument is supplied,
the output is formatted in such a way that it can be made part
of an @var{inputrc} file.  This command is unbound by default.

@ifset BashFeatures
@item glob-complete-word (M-g)
The word before point is treated as a pattern for pathname expansion,
with an asterisk implicitly appended.  This pattern is used to
generate a list of matching file names for possible completions.

@item glob-expand-word (C-x *)
The word before point is treated as a pattern for pathname expansion,
and the list of matching file names is inserted, replacing the word.
If a numeric argument is supplied, a @samp{*} is appended before
pathname expansion.

@item glob-list-expansions (C-x g)
The list of expansions that would have been generated by
@code{glob-expand-word} is displayed, and the line is redrawn.
If a numeric argument is supplied, a @samp{*} is appended before
pathname expansion.

@item display-shell-version (C-x C-v)
Display version information about the current instance of Bash.

@item shell-expand-line (M-C-e)
Expand the line as the shell does.
This performs alias and history expansion as well as all of the shell
word expansions (@pxref{Shell Expansions}).

@item history-expand-line (M-^)
Perform history expansion on the current line.

@item magic-space ()
Perform history expansion on the current line and insert a space
(@pxref{History Interaction}).

@item alias-expand-line ()

relative to the current line from the history for editing.  Any
argument is ignored.

@item edit-and-execute-command (C-xC-e)
Invoke an editor on the current command line, and execute the result as shell
commands.
Bash attempts to invoke
@code{$FCEDIT}, @code{$EDITOR}, and @code{emacs}
as the editor, in that order.

@end ifset

@ifclear BashFeatures
@item emacs-editing-mode (C-e)
When in @code{vi} command mode, this causes a switch to @code{emacs}
editing mode.

@item vi-editing-mode (M-C-j)
