In a viewport window under Show I can select what types of objects I want to display(Controllers, NURBS Curves, etc.) Oftentimes I want to only see maybe 2 or three types, so I want to deselect all by hitting "None" and then at the same time without the menu closing reselect a couple of object types, say Polygons and Lights. Currently I need to reopen the menu, tick one object type. The menu closes. The reopen again etc.. In Softimage you could just use shift while the menu is open and select or deselect as many types as wanted before closing the menu.
