/*  Pressing a key -- a number, letter, function or special keys  --
    generates a 'keyboard event' that is passed into "KeyDown()"
    as an argument.

    "char(key)" gives the UNICODE/ASCII value of the key.

HW:   COMPILE THIS.  CHANGE keyDown to keyUp.
      What is the ASCII VALUE OF LF, AND CR?
