d_keyboard_proc - Invisible dialog procedure for implementing keyboard shortcuts. Allegro game

       This is an invisible object for implementing keyboard shortcuts. You can put an ASCII  code  in  the  key
       field  of the dialog object (a character such as 'a' to respond to a simple keypress, or a number 1-26 to
       respond to a control key a-z), or you can put a keyboard scancode in the d1 and/or d2 fields. When one of
       these keys is pressed, the object will call the function pointed to by dp. This  should  return  an  int,
       which will be passed back to the dialog manager, so it can return D_O_K, D_REDRAW, D_CLOSE, etc.
