RE: Exclamation Point in DirectInput Key List

DirectInput only maps the keyboard, not every possible keystroke. There 
are no DIK_KEY constants for masked keystrokes. DIK_ESCAPE simply refers 
to the very top-left button on the keyboard, DIK_1 refers to the second 
button on the second row. Etc..

You don't have to use DInput for keyboard handling though.
I didn't document it, but if you look in exoticaX.ew, you will find a 
couple of routines for Windows keyboard handling. I use them in 
guiX_dlg.ew for the edit controls.
Actually, I believe windows handles keystrokes the same way, but it's 
alot more versatile.
I think you would encounter the same problem.
