Following the work at http://xenforo.com/community/resources/how-to-add-some-plugins-or-custom-buttons-to-redactor.1996/ I was able to successfully add my new button. With TinyMCE I was able to change what was pasted in depending if text was selected or not. For instance clicking the button would give me. Code: [tag="Hint"][/tag] While selecting text and clicking the button would give me. Code: [tag]Selected Text[/tag] Is there a method for doing this with redactor?
