Any help here? I've looked all over for an answer, and can't seem to find one. I just switched to an Apple bluetooth wireless keyboard. My old keyboard had the numbers on the right and I was able to use an on screen calculator for doing simple additions and subtractions. The bluetooth doesn't have this which I'm okay with just using the numbers on top of the keyboard instead. But every time I have to make several additions i.e. 10+2+4+9+5, I have to hit the shift key each time for the + key to function. This is a p.i.t.a! Does anyone know if there's a way to "lock" the + key while doing calculations? I hope anyone out there reading this can understand what I'm asking. Thanks for any help!
