Shake To Undo

On the iPad and iPhone, you can’t have a “Command” key to be able to hit Command+Z to undo. But there is still an undo function in most apps. For instance, when typing in Pages, you can give your iOS device a quick little shake and a small set of buttons will appear giving you the option to undo. Most other apps follow suit, so the next time you need to undo in iOS, try a little shake.
