With very long lines, that can take an > eternity. _That_ is what we should strive to fix. No argument here. My proposal changing the keyboard macro execution to switch off visual positioning was not intended as a performance fix: it might have that effect on some benchmarks, but that's purely incidental. Stuff like fill-paragraph will still require display engine calculations and I'm fine with that. Its purpose is not in any manner different during macro recording/replay so it's definitely both useful and consistent to consult the display engine. With regard to visual movement, I don't see that consistency will ever be useful in macro recording/replay. So I'd at least like to have an option (effective during both macro recording and replay since a difference between the two would be both inconsistent and useless) to get inconsistent but useful behavior here. -- David Kastrup
