One really cool thing Atari Basic did was that you could list lines x,y and just move your cursor up to the line you wanted to change and insert/delete/overtype characters. It would even handle line-wrapping of the logical line up to 3 physical lines. Press enter and that's the new line (or change the line number and it's a new source line). It was often used for renumbering a few lines to make room for more as there was no built-in renumber utility.
