Desktop feeling cluttered? You’ve got more space to work with than you might realize, thanks to BeOS‘ workspaces. Hold down the Alt key and punch the F keys, a la Alt+F2, Alt+F6, etc. You’ll get a clean workspace in each one, and each workspace can run at independent resolutions and host different running applications. You can also switch workspaces graphically, from the Workspaces preferences applet. The applet has the added advantage of letting you drag applications from one workspace to another.
