You NEED to learn about keyboard macros. And C-/ (which is undo). Actually, it helps to be around other emacs users. I've seen people do something magic and I stop them so I can learn the trick. Usually they have to do it again before they can explain it because most emacs users have everything "in their fingers". Musicians are the same. I would credit emacs with 50% of my productivity. Learn it well. It pays huge rewards.
