I've just upgraded to the 2021 Magic Keyboard with Lock Key (A2450). I used to be able to put my iMac's display to sleep using the Control–Shift–Media Eject shortcut. But now I have a Lock key instead of an Eject key. So how would I be able to put my display to sleep using a keyboard shortcut? (Without actually locking it.)
I've been able to put my display to sleep using a hot corner. I'm still looking for a keyboard shortcut, but at least I have something.
