I have Lightroom CC and my problem is the key shortcuts. When I read Keyboard shortcuts for Lightroom Classic CC and try to test them, most don't do do anything and some do something completely different from what it is supposed to do. It has been bugging me, but now, that I found out, that I can not change the Overlay composition grid, I really need your help. How can I change the shortcuts and how can I use all of the cropoverlays?
