Up/Down Arrows

[Jez]

I find it frustrating that moving the selection on a list field via the
up/down buttons does not naturally fire SelectionChanged. But I can force it
by adding the handler:

on rawKeyUp keycode
  send SelectionChanged to me
end rawKeyUp

(I could actually check the keycode but I rarely bother)

My problem is, my list worked fine until I put it in a group, whereupon my
up/down keys no longer change the selection. It still fires rawKeyUp but
since the selection point is not moved effectively nothing happens. What can
I do ?
