directional window-switching

[David Thiel]

Hello,

One feature that I would love to have in Openbox would be the
ability to switch focus to windows based on position, rather than just
next or previous. For example, the action names:

WindowRight
WindowLeft
WindowUp
WindowDown

could be used to move to the window to the right of the current one, etc.
I use this type of navigation in wmii constantly, and it's far more
convenient when faced with a grid of 9 or so xterms to hop around
directionally than to cycle through them all. Would this be doable?

Thanks,
David
