I learnt something cool about Emacs undo on a recent HN thread.

If some text is selected before invoking undo, then undo happens only within the selected region.

25 years using the thing, and I'm always learning something new about Emacs. Thanks for the tip!

this is nice. Just like bash, emacs has so many features hidden under it's hood.
