Thanks Striker - you are too kind. I am sure there are others that can find them quicker that I can (stand up Darren (dhumpie)) and know more objects than I do.
Knowing where things are comes from practice and remembering. I did have to refer to the charts once or twice if I remember correctly.
To be honest when ever I am handed a keypad I am usually found staring at the pretty lights wondering what to do next
