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

       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.
