NAME
       exkeys - How to get input from the keyboard in different ways. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       Example exkeys

DESCRIPTION
       This program demonstrates how to access the keyboard. The first part shows the basic use of readkey(). The second part shows how to extract
       the ASCII value. Next come the scan codes.  The fourth test detects modifier keys like alt or shift. The fifth test requires some focus	to
       be  passed.  The  final step shows how to use the global key array to read simultaneous key presses.  The last method to detect key presses
       are keyboard callbacks.	This is demonstrated by installing a keyboard callback, which marks all pressed keys by drawing to a grid.
