How do you reset screen zoom to zero?
I mean the one you do with control-mouse wheel, I know you can reset it with the wheel again until it gets to 1:1 but it would be nice to have a keyboard shortcut to make it 1:1
I'd say hold ⌥+⌘+–. In fact, holding ⌥+⌘+8 will disable it, but once you press it again, it comes back to the old level, therefore ⌥+⌘+– seems the best solution.
When zoom is enabled in accessibility preferences, command option - is the default shortcut for zooming out, it's not instant, but it's a pretty fast method.
The "Accepted Answer" does not work.
First you have to go into "Accessibility" (type into Spotlight), then click "Zoom", and enable the "Use keyboard shortcuts to zoom" checkbox.
