With all the RAM we have these days, it’s easy to get some serious screen clutter going on when you have a ton of apps open.
You can hide the current app with Command-H, and you can hide all the other apps except the current app with Command-Option-H.
But did you know you could go to any app that’s currently running, while simultaneously hiding all the other running apps?
All you need to do is click on the icon of the running app you want to make active in the Dock while holding down the Command and Option keys at the same time. Command-Option-Click in the Dock will activate the app you click on while hiding all the rest of the running apps on your Mac.
Think of it as a great way to focus yourself on just one specific app at a time without having to set up Spaces or switch to the app and hit Command-H once there. Efficiency!
