tree widget keyboard shortcuts

[Preben Randhol <randhol pvv org>]

Hi

I'm trying to make my app as keyboard friendly as possible. I noticed
that one can use the arrow keys in the tree widget to go up and
down. What I cannot find out is how one opens and closes a subtree. Is
there a keyboard key assign to this already or do I need to do this
myself ?

Any hint much appreciated.
