Wow, been using Emacs for decades and didn’t know about „undo in region“. Thanks for sharing!

It's one of those things like rectangle commands; once you know they exist it's hard not to miss them in editors that don't support.

Emscs undo both both of those reasons is just on another planet than any other editor. Being able to undo your undo (as infinitum) is killer because it just means you can never lose state.

Refional undoing is even more amazing.
