Hello.
I searched a way to add quicktags to the comment field.
I found
http://alexking.org/projects/js-quicktagsDownload, tweak the .js file to your needs, upload it to root and edti theme.php function
// HTML template for the form to add comments
if (!isset($template_add_your_comment)) { //{THEMES}
...
<!-- BEGIN input_box_no_smilies -->
<td class="tableb_compact">
<textarea class="textinput" id="message" name="msg_body" style="width: 550px;" rows="6"></textarea>
<script class="comment_button" type="text/javascript">edToolbar('message');</script>
<!-- END input_box_no_smilies -->
This adds quicktags.
I think adding them anywhere, eg description is as easy.
Do not forget to pay at least the one dollar 35

Only formatting the buttons with css didnt work...
