Tap to Undo with Three Fingers
Most everyone knows about the Shake to Undo feature when you make a mistake in a text field. As convenient as it is, you can’t always shake your phone. In a business meeting, it would look odd if you started shaking your phone without explanation. Thankfully, you can access the Undo and Redo toolbar in a more discrete manner!
All you need to do is tap your iPhone or iPad screen with three fingers. This three-finger tap works with almost all text fields in iOS. You can use it in notes, emails, messages, and more.
