Thanks @TW Tones! I do often find myself getting into that "Js-only" mentality. As powerful and hackable as the JavaScript language is, there are certain things it cannot do (possibly or effectively), and some of those reasons are why I need to read-up on wikitext. I will look into that great list you made, and hopefully find something on it that allows the getting of the tiddler text (I have already done the stylesheet).
I may have to really work hard to stop my bad habits, because I developed quite a long bit of code to get the text of the tiddler where the button click event fired from! Thanks Again!
