Quick key and/or eyedropper tool option for ALL CAPS and lowercase in inDesign
Having to use dropdown menu (and noting conspicuously absent quick key notation) is so tedious when you have to do this 100 times

You can set your own shortcuts in Edit/Keyboard Shortcuts. Set Product Area to Type Menu and look for the Change Case commands or set Product Area to Panel Menus and look for Character: All Caps.
