Thanks Keith Fuller & Ivaylo Iltchev, it worked fine! Do you have a list containing "all" of the hidden characters? I.e. Ctrl-v, F1 etc.? Thanks again!
You need the standard ASCII code table and a keyboard scan code table (for things like F1). I've got a little book called Pocket RCRef that I've had for years but you should be able to find them in numerous places. Try doing a web search. Good luck.
