Right, but these fall back into the case where redisplay performs a second pass trough the window/buffer, so it's similar to the scrolling case, right? >> If OTOH redisplay decides to scroll, it won't re-execute >> pre-redisplay-function, so Elisp doesn't get a chance to react to this >> new window-start. > ??? Then what are those calls to run_window_scroll_functions that > redisplay issues? Ah, right, I forgot about this. So maybe window-scroll-functions is the answer to the OP's needs! Stefan
