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.
