I have had problems with it thinking I pressed the ESC key when I pressed
the up arrow. So if you are using the up arrow you probably want to disable
the interrupt.

Normally it is better, but I never use it and it doesn't cause trouble to
me. You can also test the keys in the interrupt 1 handler if you want to be
