Is there an easy way to say "make line N" (e.g., 502) the top line of the visual screen?
I'm not sure there is much easier than
502Gzt
You could map the "Gzt" portion to something if you wanted...
:nnoremap <f4> Gzt
which will default to the last line in the file if you don't
provide a line-number.
