more function button stuff. also number pad buttons, which only work to enter arguments to certain functions right now. Need to figure out how event command is going to work, maybe assign a number for each one like 1 is ind, 2 is parind, 3 pargrp, 4 pargrp, otherwise I dont know how we would enter in the type since we dont have keys for the letters, unless we allow people to type in on the keyboard.
