What ticks me off is I know how to do the thing but it takes me forever. My wife on the other hand sits down and goes blink blink blink and done. Grrrr. If you're interested in buying one let me know I will dig up the place that sells them. They have Braille squares so you can feel them and you can get a couple types some have numbers some have words.

Can you be a little more specific?
