<h4 class="subsection">9.1.4 <code>@key</code>{<var>key-name</var>}</h4>

<p><a name="index-key-415"></a>
Use the <code>@key</code> command for the conventional name for a key on a
keyboard, as in:

<pre class="example">     @key{RET}
</pre>
  <p>You can use the <code>@key</code> command within the argument of an
<code>@kbd</code> command when the sequence of characters to be typed
includes one or more keys that are described by name.

  <p>For example, to produce <kbd>C-x &lt;ESC&gt;</kbd> and <kbd>M-&lt;TAB&gt;</kbd> you
would type:

<pre class="example">     @kbd{C-x @key{ESC}}
     @kbd{M-@key{TAB}}
</pre>
  <p>Here is a list of the recommended names for keys:
<a name="index-Recommended-names-for-keys-416"></a><a name="index-Keys_002c-recommended-names-417"></a><a name="index-Names-recommended-for-keys-418"></a><a name="index-Abbreviations-for-keys-419"></a>
<blockquote>
     <dl>
<dt><tt>SPC</tt><dd>Space
<br><dt><tt>RET</tt><dd>Return
<br><dt><tt>LFD</tt><dd>Linefeed (however, since most keyboards nowadays do not have a Linefeed key,
it might be better to call this character <kbd>C-j</kbd>)
<br><dt><tt>TAB</tt><dd>Tab
<br><dt><tt>BS</tt><dd>Backspace
<br><dt><tt>ESC</tt><dd>Escape
<br><dt><tt>DELETE</tt><dd>Delete
<br><dt><tt>SHIFT</tt><dd>Shift
<br><dt><tt>CTRL</tt><dd>Control
<br><dt><tt>META</tt><dd>Meta
</dl>
</blockquote>

  <p><a name="index-META-key-420"></a>There are subtleties to handling words like `meta' or `ctrl' that are
names of modifier keys.  When mentioning a character in which the
modifier key is used, such as <kbd>Meta-a</kbd>, use the <code>@kbd</code> command
alone; do not use the <code>@key</code> command; but when you are referring
to the modifier key in isolation, use the <code>@key</code> command.  For
example, write &lsquo;<samp><span class="samp">@kbd{Meta-a}</span></samp>&rsquo; to produce <kbd>Meta-a</kbd> and
&lsquo;<samp><span class="samp">@key{META}</span></samp>&rsquo; to produce &lt;META&gt;.

  <p>As a convention in GNU manuals, <code>@key</code> should not be used in
index entries.
