I believe the bug is correctly summarized in comment #7 (https://bugs.launchpad.net/ubuntu/+bug/774870/comments/7) with a patch to fix it.
I'm using Ubuntu 12.10 and can't configure keyboard shortcuts to switch to workspace 11 or 12. If I configure my shortcuts that I normally use for workspace 11 or 12 (Ctrl+F11 or Ctrl+F12) to workspace 10 then they work as expected. If I configure my shortcut key for workspace 10 (Ctrl+F10) to workspace 11 or 12 then it doesn't work. ** Branch linked: lp:compiz-plugins-main -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/774870 Title: Alt-F11 and Alt-F12 keybindings no longer work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/774870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
