Shake to Undo

Shake to Undo 1.0

The tiny app works by activating Command+Z when movement is detected by the SMS

Once the application is running, simply shake your laptop to activate undo. To prevent accidental activation of the undo gesture, there is an optional confirmation overlay, similar in style to the undo overlay on iOS.
Shake to Undo works in Safari, Mail, Notes, Messages (SMS), Calendar, and similar apps.
