Thanks I appreciate it. I've had some luck displaying a pop up menu in the textarea right at the cursor position (thanks to you!) but I'm now having some trouble working with the events and getting it to do what I'd like it too. If its not much trouble, if you come across what you did please email me. Thanks again for making this post. Didn't think I was going to find anyone who was trying to do something similar.
I took a quick peek at what we did for the pop up menu and we are just using a list control. We change its visibility and add/removing event listeners where appropriate.
We did have to do some data tracking to manage when the list showed so the user could dismiss the list box and keep typing - that was the only hic-up we really encountered though.
