Grant,
Thanks for your reply! But I found that on Windows, both '+' and right
arrow key can expand tree node. So you mean on Linux, it was limited to
'+' only?
Thanks again!

Yes. We just wrap the native widgets, so if the native win32 tree has
multiple expand/collapse keys, then this will be reflected in the swt tree
on win32 for free. Similarly, if you run gtk-demo on linux you'll see that
only +/- are used for expanding/collapsing items in native gtk trees, so the
swt tree on gtk has (by inheritance) this same behaviour.
