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 on a line in the init file the name of the
key you wish to bind the command to, a colon, and then the name of the command. The name of
the key can be expressed in different ways, depending on what you find most comfortable.
In addition to command names, readline allows keys to be bound to a string that is inserted when
the key is pressed (a
macro
).
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: "
Z
output"
In the above example,
C-u
is bound to the function
universal-argument
,
M-DEL
is
bound to the function
backward-kill-word
, and
C-o
is bound to run the macro ex-
pressed on the right hand side (that is, to insert the text
Z
output
into the line).
A number of symbolic character names are recognized while processing this key binding
syntax:
DEL
,
ESC
,
ESCAPE
,
LFD
,
NEWLINE
,
RET
,
RETURN
,
RUBOUT
,
SPACE
,
SPC
, and
TAB
.
"
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 again 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
