    Try searching for it on this board.

    The main theme you'll find is that you won't be able to without pulling your hair out.

    I havent played with this much myself, but I think what it means is that you're dealing with a sequence of 2 characters.

    After you receive 0x00, 0x01 would mean that SHIFT_R has been pressed.
