Mac 101: Apply actions to multiple windows
Here's a tip for those who take a tidy desk to the extreme. When you've got multiple Finder windows open, you can apply an action to all of them at once.
Press Command-Option-W to immediately close all windows. Likewise, if you hold down the Option key while pressing the red, yellow and green buttons in the upper left hand corner of a Finder window, you apply the corresponding action to all open windows
Option + yellow minimizes all windows to the Dock
Option + green maximizes all windows
Option + red closes all windows
Keep your desktop neat and tidy by dismissing all open Finder windows in a snap.
