Default Quicktags

Here are the values of the default Quicktags added by WordPress to the Text editor (table sorted by access key value). Access key and ID must be unique. When adding your own buttons, do not use these values:

Accesskey	ID	Value	Tag Start	Tag End
a	link	link	<a href="' + URL + '">	</a>
b	strong	b	<strong>	</strong>
c	code	code	<code>	</code>
d	del	del	<del datetime="' + _datetime + '">	</del>
f	fullscreen	fullscreen
i	em	i	<em>	</em>
l	li	li	\t<li>	</li>\n
m	img	img	<img src="' + src + '" alt="' + alt + '" />
o	ol	ol	<ol>\n	</ol>\n\n
q	block	b-quote	\n\n<blockquote>	</blockquote>\n\n
s	ins	ins	<ins datetime="' + _datetime + '">	</ins>
t	more	more	<!--more-->
u	ul	ul	<ul>\n	</ul>\n\n
	spell	lookup
	close	close

(Some tag values above use variables, such as URL and _datetime, passed from functions.)
