If you find yourself typing an Email or note on your device but you wish to delete everything you have just written then all you need to do is give it a shake.
Doing so will bring up the following screen:
From here you can select to Undo Typing or simply cancel. Your device will only undo a certain amount of typing at a time. Usually around a sentence at the maximum. Please also note that once you leave the app, should you go back and wish to undo typing the device will not allow you to do so. You will need to manually delete any content you wish to have removed by either highlighting it or pressing the delete key repeatedly.
I know you enjoyed shaking your iOS device the first time so lets do it again. By doing it directly after you hit Undo Typing the following will appear:
As you will notice from the image above you again have Undo Typing but now you also have redo typing. Should you press Undo Typing again then the rest of the sentence in question will be removed.
Redo Typing will put back what you have undone should you wish to keep the content you have just removed.
You can use this handy feature anywhere typing is being entered on your iPad, iPhone, or iPod touch.
