The up arrow arrow key increments
the pgUp key increments
the Home key goes in the oposite direction that the above two keys go.

The Home, upArrow, and PgUp keys are all at the top of the keypad
and it is natural to think they would move that way.

The Home key move down to the min value instead of to the max value.

The same applies to the 
End, downArrow, and PgDn keys but in the opposite direction.

Make the Home key go twords the max value
and the End key go twords the min value.
