I would like to have smarter screen scrolling when I'm editing. When I reach within X number of lines from the top/bottom of the screen, I would like it to scroll the screen as I continue moving the cursor (so I can always see, at minimum, X lines below or above).
I know ctrl-y and ctrl-e will scroll, but is there a way I can have vim detect when I hit j or k how far I am from the top/bottom of the screen so it can move the screen as needed?
I also know zz will center on the current cursor location, but I'd like there to be an area where it doesn't scroll.
Thanks.
