Ever get a 3D model online with a bunch of Selection Tags? Maybe they aren't even named and you find yourself lost sliding through the object manager clicking on Tags to find what you need. Luckily there is a drop down menu function to help you find selections faster in Cinema 4D. If you find yourself using shortcuts or the Shift - C function rather than the menus you may overlook this function just like I have over the years. This is a simple yet useful tip.
