Hi John, I think that would be a wondful idea..!! And I have no clue how you would do this but for those of us who see light, perhaps you can make a brite light as well? And the function when one makes a mistake and accidently presses the backspace key. There is a sound to let you know that you pressed it but if one can't hear nothing how would they know??? I hear it because I can hear a lot with hearing aids, but for those who can't this would be a great thing to have.
