Using TinyMCE

1. Copy and Change tinymce_setup.js

Copy tinymce_setup.js (in order to not break future updates) and adjust the setup/behaviour of TinyMCE according to your needs - see http://wiki.moxiecode.com/index.php/TinyMCE:Configuration

2. Change the media-definition of your ModelAdmin

    class Media:
        js = ['/media/admin/tinymce/jscripts/tiny_mce/tiny_mce.js', '/path/to/your/tinymce_setup.js',]

3. Check the file tinymce_setup.js and change it (if you need to).
