While in full-screen mode, keyboard access is limited. Your code will still respond to the
following keys: Tab, Enter, Home, End, Page Up, Page Down, Space, and the arrow keys.
All other keys are ignored. This means that you can build a simple full-screen arcade
game, but you can’t use text boxes or other input controls. This limitation is designed to
prevent password spoofing–for example, tricking the user into entering a password by
mimicking a Windows dialog box.
