Hi Chuck,

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.
