Add keyboard shortcut to DIM SCREEN
Settings > Power > Blank Screen allows one to set a countdown before the screen dims.
I request that a keyboard shortcut be created that can cause the screen to Dim on command. A problem I run into is that I step away from my computer, a message arrives (e.g., email), then the screen dims. I return to computer and the screensaver (that shows the time) reports no new messages because the email arrived before the screen dimmed.
If I could tap a keyboard shortcut to make the screen dim before I leave my station, then new notifications would show on the screensaver when I check it later on.
Please note that I do NOT want the screen to lock. CTRL+L will dim screen and lock it. But I want a different keyboard shortcut that will dim the screen but not lock it.
