d_keyboard_proc - Man Page

#include <allegro.h>

int d_keyboard_proc(int msg, DIALOG *d, int c);

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.
