It is PART OF a design. The more important but not implemented in emacs part is to quit redisplay prematurely when new input arrives. Basically like: (while-no-input (redisplay) ) In practice, editors did it like this (which gives nice feedback on the spot where the eyes look at): (while-no-input (redisplay current-line) (redisplay rest-of-page) ) --- grischka
