Arrow keys in datagrid

[Marty Knapp]

I have a "form" style datagrid and when I use the arrowKeys to try to 
scroll through the records, the down arrow works as expected, but when 
you press the up arrow, it deselects the row and pressing it a second 
time it goes right to the first record rather than the previous record. 
There is one exception to this - if row 2 is selected and you press the 
up arrow key, it will select row 1. I don't see any arrowKey handlers 
anywhere. Any clues?

Thanks,
Marty K.
