How can I reduce or increase the number of workspaces in Unity?
This video from a Unity developer shows him clicking on the workspace button in the launcher to use multiple workspaces (aka virtual desktops). On my 2 netbooks clicking on that button only invokes the expose-like effect.
Is there a setting somewhere I can use to get this functionality, and if so, what is the keyboard shortcut to go along with it?
