I find that right clicking on the top level assembly and toggling between View Features and View Dependencies is completely invaluable. Sorting thru the forever-long list of mates is made much simpler when I can see them under the parts they pertain to. Unfortunately I toggle back and forth quite frequently and was wondering if anyone has a shortcut for this. Ideally, I'd like a toolbar button that toggled between modes. I'd write a macro, but I don't know how to select View Features or View Dependencies besides right clicking on the top level assembly. Anyone got any good way to do this?
