|
|
|
|
<p>The following paragraphs describe the notation used to represent
|
|
keystrokes.
|
|
|
|
<p>The text <kbd>C-k</kbd> is read as `Control-K' and describes the character
|
|
produced when the <k> key is pressed while the Control key
|
|
is depressed.
|
|
|
|
<p>The text <kbd>M-k</kbd> 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.
|
|
|
|
<p>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>
|
|
<em>first</em>, and then typing <k>.
|
|
Either process is known as <dfn>metafying</dfn> the <k> key.
|
|
|
|
<p>The text <kbd>M-C-k</kbd> is read as `Meta-Control-k' and describes the
|
|
character produced by <dfn>metafying</dfn> <kbd>C-k</kbd>.
|
|
|
|
<p>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
|
|
(see <a href="Readline-Init-File.html#Readline-Init-File">Readline Init File</a>).
|
|
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.
