Putting a DWF file in any program that usescontrols, such as Buzzsaw, is referred to as embedding a DWF file.
When the embedded DWF file is active, the default DWF viewing program limits the amount of Design Review application window that is shown. Typically in embedded situations, the Design Review ribbon only shows the tab names. Clicking a tab name temporarily opens the ribbon so you can access the appropriate tools. Since embedded mode does not show the Quick Access toolbar, the tools typically found on the Quick Access toolbar are shown on the panel on the tab.
