That's a good idea for a nice tinymce button!
If you have the sef bot published you can create links like this:index.php?option=com_xxx&task=yyy&Itemid=zzzElse if you have SEO PRO enabled, you can use directly the SEO PRO links. Examples:http://www.mysite.com/links/http://www.mysite.com/section/category/title.htmlThese links will stop from working if you, some day, disable SEO PRO.
