I don't think this is possible, it looks like the notebook widget itself
is one window that catches the <Tab> event and decides what to do - draw
the focus indicator onto the next tab or pass the focus to another window.

But, a far as I see, at least here with IceWm any time a tab receives the
keyboard focus it will be selected as well, so maybe you can play around
with the select mechanism, depending on what exactly you want to achieve.

Michael
