Several specialized quad menus are available when you are working in certain modes, such as ActiveShade, Edit UVWs, Track View, or when you press any combination of Shift, Ctrl, or Alt while right-clicking any standard viewport.

The ActiveShade quad menu provides many useful commands such as Render, Draw Region, Update, as well as access to the Material Editor. Similarly, the Unwrap UVW quad menu contains many common UVW commands.

You can create or edit any of these menus from the quad set list in the Quads panel, on the Customize User Interface dialog; however, they cannot be deleted.

These are the additional quad menus and their default settings:
