You can use Shake to quickly minimize every open window except the one you're shaking. This feature can save you time if you want to focus on a single window without minimizing all your other open windows one by one. You can then restore all of those windows by shaking the open window again.
Some windows, such as open dialog boxes, cannot be minimized using Shake.
For the window you want to keep open, drag (or shake) the title bar back and forth quickly.
To restore the minimized windows, shake the open window again.
