title: Textarea toolbar?
body: <p>I have been working on a formatting toolbar for a textarea, much like the toolbar for writing questions on this very site (with the bold, italic, underline buttons). The only difference is that I need the buttons to make the text actually bold not just add a bold tag. What I need is similar to the Instructables.com rich comment editor, or the newgrounds.com comment editor, or  google docs. Does anyone have a clue how I can make some text in a textarea show up bold, italic, or underlined but keep the rest of it?</p>
