    NOTE:  EXTENDED KEY HANDLING OPTIONS
        This header allows keys with extended codes to be defined 3
        different ways depending on what is defined when the file
        is included in the source.

        KEY_INT defined:
            The scan code of the key is returned as the high byte
            and the NUL char is returned as the low byte.  This is
            exactly as the the BIOS read key routine returns extended
            keys.   Ex:  F1 == 0x3b00

        KEY_CH defined:
            Extended keys are defined as the value of the scan code.
            This method works well when using the getch() functions --
            on the first call a NUL is returned, on the 2nd the values
            defined using this method is returned.
                Ex:  F1 == 0x3b

        KEY_NEG defined:       * * *  this is the default  * * *
            Extended keys are defined as the inverse of the scan code.
            Use this if you have a function that returns the 'scan code/char'
            for normal keys but returns negative scan values for extended
            keys.  The advantage of this method is if the value returned is
            less than 0, you know an extended key was pressed since the
            scan codes/char combinations don't have negative integer values.
                Ex:  F1 == (0 - 0x3b)
