Q About GtkCTree

["Erik Turner" <erik turner org>]

I've got a question about navigating a GtkCTree with
the keyboard.

Is there a keyboard method for expanding/collapsing
nodes?  I've been able to control everything else with
the keyboard.  I thought about trapping Left/Right 
arrows but these seem to be used for navigation 
between widgets.

Any help would be appreciated,
