Hackers Keyboard has that via ctrl+z, but only in horizontal mode. For this only i had my Galaxy S3 in horizontal per default. But can’t do that with modern phones’ aspect ratio and i’m missing undo since then.
You don’t, or at least I never have. Once it’s gone, it’s just gone.
Then a proper undo function would have some merit over the backspace if you ask me.
