The untabbed controls are a series of buttons that appear at the top left of the screen. Their layout may be different from that shown below if you have resized the Rave window to be very small.
Table/Workspace Mode Button
Create New Workspace Object
Clicking this button opens the Create New Workspace Object gui. This is the same as clicking the "Create New..." button on the Manage Tab.
Toggle Full Screen Mode
Clicking this button toggles between the Painters renderer (default) and the OpenGL renderer. Read Renderers in Rave for more information. The clock indicates that OpenGL is generally much faster than Painters, but it suffers from several MATLAB bugs.
