clickable symbols to insert

Question

I have a site where users can type posts. I want to add an some simple buttons on the side of the site that insert different symbols. The symbols dont need to be crazy like the windings font but just some basic math symbols. Also, how could I add the ability to highlight and make a selection a subscript (like Microsoft word)? Thanks.

You should consider using TinyMCE or CKEditor for your textarea. They both allow users to input custom characters (Look for the Ω - Omega symbol on the toolbar).
