Just a little more help because I'm being super thick - what exactly
does "keypad application mode mean"? I understand the difference
between numeric mode and non-numeric, or I'm assuming that it works the
same way it does on PC. But the "application mode" thing is throwing me
off because I don't know what it means and can't draw my own analogies.
