thinking that i am the author i can best explain how it works. First it
waits for you to press a key(1-4) then it jumps to the approiate
location then it turns off the calc(items 1 and 2) or goes back to
ZShell or the Home Screen(items 3 and 4). if 1 or 2 is pressed it turns
off the calc and then waits for on to be pressed. after ON is pressed
CalcOff2 either is set to go to ZShell or the home screen.
