    I think what you want to do is have focus follow your arrow keys
(and obviously draw some kind of focus indicator). I really doubt
that GTK+ can do anything about this, I think that you'll need to
configure your X server in a way that your arrow keys act like
arrow keys on a keyboard, then it should "Just work".

Note that you might need to take special care with some widgets
that grab focus, i.e. arrow key cant be used to navigate out of
a spin button for example.
