In the Workspace, you'll find four toolbars: Menu2D or 3D DocumentBrowsers, and Standard. The 2D and 3D Document toolbars enable you to view, measure, and annotate your documents; the Browser toolbar is used to display and change assembly information, notes, markups, and views. 

The Menu toolbar contains two menus with commands specifically for managing documents: the File menu (opening, closing, manipulating files) and the Tools menu (creating custom formats for printing).
