Oops! I forgot all about the class of editors used all the time on IBM 3270 family terminals. These are half-duplex devices with local on-screen editing and the ability to encode only the changes to the screen to let the host know what's happening. Modern 3270 full-screen editors are indeed quite powerful. I will not risk religious war by rating them against Emacs. /jr
