Treeview, avoid selecting node on keydown or up

[RB Smissaert]

Is there a way to avoid the behaviour of the userform treeview control where
a different node gets selected when the node text starts with the letter of
the pressed key.
The problem is that I have keyboard shortcuts that do various things in the
treeview and these get messed up by this.
These routines get triggered by the keyup event. Can't remember now why this
isn't in the keydown event, but there was a good reason for it.
