I have installed Elementary OS on my iMac 5k (17.1) and it looks stunning. However I'm missing a feature from macOS that I grew quite fond of. When I move the mouse into a corner of my Desktop the screen is turned of (not locked!!). I do this frequently to save energy. But I don't want this to happen immediately but after a minor timeout (500ms) so the screen does not turn dark when I move the mouse the the corner accidentally (for instance when trying to shut the computer down).
Is this possible with hot-actions?
