The "cool editor feature" that has most impressed me lately is vim 6's block-based text folding. Put a descriptive comment at the top of each block, fold down a level or two, and it's really easy to get a quick overview of how a program is structured.
(I'd be surprised if something similar hasn't been written for emacs. No editor holy wars please!)
