switch view port with keyboard shortcut

["Daniel Fetchinson" <fetchinson googlemail com>]

Hi folks,

I seem to remember that older sawfish versions allowed me to switch
view ports via keyboard shortcuts. I have only 1 workspace but a 2 x 2
grid of view ports:

(define-special-variable viewport-dimensions '(2 . 2) "Size of each
virtual workspace.")

Now with 1.3.1 I'm not sure if I can do the same thing, the old
keyboard shortcuts don't work. And in sawfish-ui > Bindings > set
viewport linear X is not there anymore where X was 0,1,2,3 before.

Is there a way?

Cheers,
Daniel
