This Underrated iPhone Feature Saves Time Deleting What You Typed – SlashGear

To see this trick in action, fire up the Notes app and open a fresh note to start typing on. Next, with your iPhone in your hand, give the device a brief physical shake. Doing this should produce an “Undo Typing” pop-up on screen. When you tap “Undo,” it will delete all the text that was previously typed. Of course, if it was an accidental iPhone shake, you can hit “Undo” and resume typing without deleting anything.

It is important to note that the Shake to Undo feature is not limited to erasing typographical errors. Depending on when you execute the shake, your iPhone will correct whatever typing-related action you last performed. For example, if your last move was to delete a series of words, shaking the device and hitting “Undo” will bring back what you just removed. It also works on any body of text that was copy-pasted into the text area of whatever Apple app you’re typing on. Essentially, it’s a generic undo tool that’ll skip back one previous app action. It can be performed any number of times if there’s a need to take back a series of actions, including typing errors.
