## The `onKeyUp' callback

Event number: 2
Generated for: Any control which can receive the input focus

A Key Up event is generated when the user releases a key whilst the object has the input focus. The event-specific parameters in ŒEV are (in index origin 1):

            ŒEV[6]         Raw ASCII code for this key
            ŒEV[7]         APL's translated code for this key
            ŒEV[8]         Scan code (ie key number)
            ŒEV[9]         Modifiers:
                           (0=unshifted, 1=shifted, 2=alt/option,
                           4=control, 8=command, and sums thereof)
