Thanks rps. Yes, that is what I meant.
I often want to delete multiple lines, but the window is scrolling (i.e. there is too much content to be shown in one window). Since I can not mark multiple lines and then delete them (which would be another nice feature), I often have to press DEL multiple times, but after deleting the first line the window scrolls so the selected line is at the bottom of the screen. Thus, I cannot see how many more lines to delete. It would be much easier and less confusing if, after a deletion, the window would not scroll.
