By default, RHEL 6 configures two workspaces.
To increase the number of available workspaces :
1. Right click with the mouse on the workspace control in the panel.
2. Select Preferences.
3. Simply increase the Number of workspaces value to the desired number.
The name of each workspace may be changed by double clicking on the default name in the list
(Workspace 1, Workspace 2 etc) and typing in a new name.
