Add keyboard shortcut for moving between workspaces

[brainsail]

Binary package hint: gnome-control-center

I am suggesting a keyboard shortcut that walks through workspaces just like the
famous "Move between windows, using a popup window" does. All workspaces would
be accessible with one shortcut, so you don't have to think where you want to
go and select the shortcut for left/right or workspace number. This is
especially useful when you have only two workspaces. Then it's always the
'other' workspace where you want.

I'm missing this feature in Ubuntu 9.04 alpha 4, in Gnome 2.25.5.
