Right now it's impossible (for me) to find/set the keyboard shortcut for locking the screen. The best place for finding/setting it would in the Screen Lock settings. I've had to help a friend and now for my new computer also, I cannot find it. Please see if you can add the shortcut setting to the Screen Locker settings. Reproducible: Always
