Be careful! Key.Code returns the code of the key. Use Key.Text if you want the 
text typed by the user. To test a specific key, for example 'A', use Key.Code 
= Key["A"]. To test 'F12', use Key.Code = Key["F12"], and so on. Never use 
hard coded values directly, this is a very bad programming pratice!
