Examples

// add more buttons to the html editor
function appthemes_add_quicktags() {
    if (wp_script_is('quicktags')){
?>
    <script type="text/javascript">
    QTags.addButton( 'eg_paragraph', 'p', '<p>', '</p>', 'p', 'Paragraph tag', 1 );
    QTags.addButton( 'eg_hr', 'hr', '<hr />', '', 'h', 'Horizontal rule line', 201 );
    QTags.addButton( 'eg_pre', 'pre', '<pre lang="php">', '</pre>', 'q', 'Preformatted text tag', 111 );
    </script>
<?php
    }
}
add_action( 'admin_print_footer_scripts', 'appthemes_add_quicktags' );

(Note: to avoid a Reference Error we check to see whether or not the 'quicktags' script is in use.)

The above would add HTML buttons to the default Quicktags in the Text editor. For example, the "p" button HTML would be:

<input type="button" id="qt_content_eg_paragraph" accesskey="p" class="ed_button" title="Paragraph tag" value="p">

(The ID value for each button is automatically prepended with the string 'qt_content_'.)

Here is a dump of the docblock from quicktags.js, it's pretty useful on it's own.

/**
 * Main API function for adding a button to Quicktags
 *
 * Adds qt.Button or qt.TagButton depending on the args. The first three args are always required.
 * To be able to add button(s) to Quicktags, your script should be enqueued as dependent
 * on "quicktags" and outputted in the footer. If you are echoing JS directly from PHP,
 * use add_action( 'admin_print_footer_scripts', 'output_my_js', 100 ) or add_action( 'wp_footer', 'output_my_js', 100 )
 *
 * Minimum required to add a button that calls an external function:
 *     QTags.addButton( 'my_id', 'my button', my_callback );
 *     function my_callback() { alert('yeah!'); }
 *
 * Minimum required to add a button that inserts a tag:
 *     QTags.addButton( 'my_id', 'my button', '<span>', '</span>' );
 *     QTags.addButton( 'my_id2', 'my button', '<br />' );
 */

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.)
