This might be a stupid question, but is there a kind of "modern" line editor, maybe with jump-to functionality, that would only show me one line of code at a time?

I wonder if programming like that would force an improvement in my code: kind of like programming through a keyhole, rather than the information overload of 20 documents open simultaneously.

Maybe an Emacs mode with Intellisense, that only showed a line at a time, with syntax highlighting?

Well, you could always set your window to be only one line high, that would have much the same effect.

Never used it standalone but I'd think that is what "ed" is?
