Use the iPhone Shake to Undo Gesture

OneNote Mobile for iPhone integrates with Apple's native iOS gesture controls. Rather than searching for a tiny button on the interface, you can physically shake your device to undo your most recent text input or deletion.
While editing a note in OneNote Mobile, recognize the accidental deletion or typing mistake that you want to revert.
Firmly shake your iPhone three or four times in a quick back-and-forth motion.
A system popup will appear on the screen asking if you want to 'Undo Typing'. Tap the 'Undo' option to instantly revert your last edit.

Frequently Asked Questions
Why is the Undo prompt not appearing when I shake my iPhone?
The 'Shake to Undo' feature might be disabled in your iOS settings. To enable it, navigate to Settings > Accessibility > Touch, and turn on the switch for 'Shake to Undo'.
Can I redo an action if I accidentally undid it in OneNote Mobile?
Yes. If you accidentally undo an action, you can shake your iPhone again to bring up the prompt, which will now give you the option to 'Redo Typing'.
Is there an on-screen Undo button in OneNote for iPhone?
In current versions of OneNote for iOS, there is often an Undo/Redo arrow pair located on the toolbar directly above the keyboard. However, if that toolbar is hidden or collapsed, the shake gesture remains the fastest alternative.
Does the shake to undo trick work on iPad as well?
Yes, the shake to undo gesture is an iOS and iPadOS system feature, so it works on iPads. However, shaking a larger tablet can be cumbersome, so using the on-screen Undo arrows is generally recommended for iPad users.
