Your code looks fine, as far as the keyboard routines are concerned.  
You ought to check the return value from set_gfx_mode, technically, 
in case it fails, so that you can tell the user gracefully.  Also 
note that 640x400 is a slightly odd resolution; it's probably better 
to use more standard resolutions in test programs.

Did you use Ctrl-F9 to run the program?  I don't use RHIDE, so 
haven't tested this theory, but perhaps when you run the program and 
Allegro takes over the keyboard, the BIOS doesn't notice that the 
Ctrl key is released, and so when the Allegro program exits and 
returns control to the BIOS handler it thinks that you're still 
holding down the Ctrl key.  Consequently, when you press other keys 
RHIDE thinks you're using keyboard shortcuts.

Try pressing and releasing the Ctrl keys after running the Allegro 
program.  Also try choosing the `Run' option from the menu, either 
with the mouse or keyboard.
