of these produces a match, filename completion is attempted.
.BR Gdb ,
on the other hand,
allows completion of program functions and variables, and
only attempts filename completion under certain circumstances.
.TP
.B possible\-completions (M\-?)
List the possible completions of the text before point.
.TP
.B insert\-completions (M\-*)
Insert all completions of the text before point
that would have been generated by
\fBpossible\-completions\fP.
.TP
.B menu\-complete
Similar to \fBcomplete\fP, but replaces the word to be completed
with a single match from the list of possible completions.
Repeated execution of \fBmenu\-complete\fP 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 \Bbell\-style\fP)
and the original text is restored.
An argument of \fIn\fP moves \fIn\fP 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 \fBTAB\fP, but is unbound
by default.
.TP
.B delete\-char\-or\-list
Deletes the character under the cursor if not at the beginning or
end of the line (like \fBdelete-char\fP).
If at the end of the line, behaves identically to
\fBpossible-completions\fP.

.TP
.B start\-kbd\-macro (C\-x (\^)
Begin saving the characters typed into the current keyboard macro.
.TP
.B end\-kbd\-macro (C\-x )\^)
Stop saving the characters typed into the current keyboard macro
and store the definition.
.TP
.B 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.
.PD
.SS Miscellaneous

.TP
.B re\-read\-init\-file (C\-x C\-r)
Read in the contents of the \fIinputrc\fP file, and incorporate
any bindings or variable assignments found there.
.TP
.B abort (C\-g)
Abort the current editing command and
ring the terminal's bell (subject to the setting of
.BR bell\-style ).
.TP
.B do\-uppercase\-version (M\-a, M\-b, M\-\fIx\fP, ...)
If the metafied character \fIx\fP is lowercase, run the command
that is bound to the corresponding uppercase character.
.TP
.B prefix\-meta (ESC)
Metafy the next character typed.
.SM
.B ESC
.B f
is equivalent to
.BR Meta\-f .
.TP
.B undo (C\-_, C\-x C\-u)
Incremental undo, separately remembered for each line.
.TP
.B revert\-line (M\-r)
Undo all changes made to this line.  This is like executing the
.B undo
command enough times to return the line to its initial state.
.TP
.B tilde\-expand (M\-&)
Perform tilde expansion on the current word.
.TP
.B set\-mark (C\-@, M\-<space>)
Set the mark to the point.  If a
numeric argument is supplied, the mark is set to that position.
.TP
.B 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.
.TP
.B 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.
.TP
.B 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.
.TP
.B insert\-comment (M\-#)
Without a numeric argument, the value of the readline
.B 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 \fBcomment\-begin\fP, the value is inserted, otherwise             
the characters in \fBcomment-begin\fP 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
.B comment\-begin
makes 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.
.TP
.B 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 \fIinputrc\fP file.
.TP
.B 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 \fIinputrc\fP file.
.TP
.B 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 \fIinputrc\fP file.
.TP
.B emacs\-editing\-mode (C\-e)
When in
.B vi
command mode, this causes a switch to
.B emacs
editing mode.
.TP
.B vi\-editing\-mode (M\-C\-j)
When in
.B emacs
editing mode, this causes a switch to
.B vi
editing mode.
.PD
.SH DEFAULT KEY BINDINGS
.LP
The following is a list of the default emacs and vi bindings.
Characters with the eighth bit set are written as M\-<character>, and
are referred to as
.I metafied
characters.
The printable ASCII characters not mentioned in the list of emacs
standard bindings are bound to the
.B self\-insert
function, which just inserts the given character into the input line.
In vi insertion mode, all characters not specifically mentioned are
bound to
.BR self\-insert .
Characters assigned to signal generation by
.IR 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 emacs mode meta keymap.
The remaining characters are unbound, which causes readline
to ring the bell (subject to the setting of the
.B bell\-style
variable).
