How do you undo an edit in Android?

So you're typing a text message or email, and you accidentally delete a huge block of text and you want it back. You immediately think "undo".

The iPhone's iOS has shake to undo, Windows Phone has ctrl+Z to undo, so how do you undo an edit you've performed in Android?

As of Android Honeycomb, you can't. Despite the feature seeming incredibly rudimentary, surprisingly enough there is no undo feature in Android. The lack of the feature is much maligned and has been brought to the attention of the Android developers. If you'd like to add your name to the list of folks that want an undo feature in Android, check out the link below.
