I'm using Ubuntu 14.04 and I'm trying to setup a few keyboard shortcuts for switching to specific workspaces, but the one for switching to #11 doesn't work.
The problem seems to be exclusive to workspace #11. For example I can set the shortcut for Switch to workspace 9 to Alt + 1 and it works fine, but when I set Switch to workspace 11 to Alt + 1, Ubuntu acts as if there wasn't a shortcut at all (eg. it activates Firefox's Alt + 1 shortcut of switching to the first tab)
Is there something I can do to correct this behavior, or is this a bug in Ubuntu?
