I recently bought the number keypad extension to Apple's wireless keyboard, and now I have so many extra function keys, I don't know what to do with them all. Being a student studying Computer Science, I would find it extremely convenient if I could use this number pad to input answers to my online math homework sites. However, most of our problems are complex and involve the use of () parentheses to divide equations into elements. Is there a way, and if so how, to program two function keys on that device to represent the () parentheses?
