<H2>DESCRIPTION</H2>
glutKeyboardFunc sets the keyboard callback for the current window.
When a user types into the window, each key press generating an ASCII
character will generate a keyboard callback. The key callback parameter
is the generated ASCII character. The state of modifier keys such as Shift
cannot be determined directly; their only effect will be on the returned
ASCII data. The x and y callback parameters indicate the mouse location
in window relative coordinates when the key was pressed. When a new
window is created, no keyboard callback is initially registered, and ASCII
key strokes in the window are ignored. Passing NULL to
glutKeyboardFunc disables the generation of keyboard callbacks.
During a keyboard callback, glutGetModifiers may be called to
determine the state of modifier keys when the keystroke generating the
callback occurred.
Use glutSpecialFunc for a means to detect non-ASCII key
strokes.
