From memory... I had the same problem. I figured out how many items were in
the scroll window and then divided by two (i.e., 30/2 = 15). I then
selected an item that was 15 up from the item I wanted to show and then
selected the item I wanted to show. Something like:

  FN viewListItem(_alphaList1,foundFirst+15)
  FN viewListItem(_alphaList1,foundFirst)
