Hi. Thanks for your answer.

How can I change between the full form and the mini form? Is it a parameter or I must install another sources?

I have the toolbar added to a FCKEditor inside a test LMS server (Sakai), I would have to register your mail if you want to see it.

Your test editor (http://www.codecogs.com/latex/eqneditor.php) has a similar aspect that the mine.

Regards.
