>What I am trying to do is to select a block of code and when I press a function key, it will copy the selected text to the clipboard, put in my comments, then insert the text from the clipboard back into the editor. This way, I now have the code I am going to edit nicely marked.

I don't know the answer offhand, but I'll bet that the script object created for IntelliSense processing has a property to give you the selected text. I'm pretty sure it's documented in Help.
