Comment 7 for bug 774870

I've done a little more research, and I think the duplicate status is wrong for this ticket. Bug 772242 appears to be a problem with Tomboy and the use of the F11 and F12 keys. This bug is an inability to use keybindings to switch to workspaces 11 and 12.

The root cause of this bug is a failure of compiz's "vpswitch" plugin to handle keybindings related to workspaces 11 and 12. This causes a mismatch between the number of workspaces exposed in the keybinding config (vpswitch.xml), and the number of workspaces actually handled by the plugin. (The interaction between the gnome keybindings page and the compiz vpswitch key-binding settings is not completely clear to me, but one passes through to the other and they both list 12 workspaces; the plugin only handles 10 of those.) The fix is to make the plugin handle the key-bindings advertised in the plugin config.

The attached patch fixes the issue for me.
