YeeHa!

I completely agree and I stated in the question that I thought it would be best as a key press, not full-time. That said, there are times that I would like to spell check some code (comments, output, error messages, etc.) It would be extremely helpful to be able to highlight some text and push F7 (or whatever) and have that section checked.

Anyway, its just a suggestion.
