Is there a way program another key to function as the alt key? I want to use my right hand to press alt so I can use my left hand to press the number keys.

I've been wondering that myself. I've been searching and haven't found any way to do this. I've been using the num lock (Alt+Shift) if I have to enter more than a few numbers in a row to get me by.

I also just use the (Alt+Shift) for long number entries
