I often use :line to jump to a line number. How can I automatically center that line vertically after jumping? Essentially the same as running :150zz.

  • Wait. This doesn't happen for you automatically? Every time I enter a line number at the command line the jumped-to line is vertically centered. Oh wait...maybe you mean when the jump is small (i.e. the visible lines don't change). Is that right?

  • No, it never happens. If the page has to scroll then the cursor is at the very extremes of the page (either top or bottom). Commented May 17, 2021 at 19:38
  • You can probably get close with set scrolloff=998, but that has other effects (I prefer more like 5 or so).

  • How strange. Even with -u NONE or --clean I get cursor line centered as long as the jump is to a line not currently on screen. You might try that too (vim --clean filename)...it may indicate that your current config has something preventing the behavior I describe.

  • @BLayer it works for me the way you describe only for help buffers. All others are as OP describes.

1 Answer 1


It looks like "centering" depends on the length of the jump with the rough ratio (window lines / jump lenght) == 0.625:


  • you have 45 window lines and you jump more than 69 lines or
  • you have 22 window lines and you jump more than 33 lines or
  • you have 15 window lines and you jump more than 23 lines

then cursor would be centered in window, otherwise not.

I am not sure if there is an option that you can use to change "jump center size", but set scrolloff=999 makes your cursor almost always be centered.

Another option would be to map command line <CR> to zz after a range:

cnoremap <expr> <CR> (getcmdtype() == ":" && getcmdline() =~ '\d\+') ? "<CR>zz" : "<CR>"
  • Hmm. Made sense to me when I thought it was determined by the target line being visible or not. This ratio driven formula...not so much. Wonder what the rationale is behind it.

  • @Maxim Kim Shouldn't part of the comparison in your answer be getcmdline() =~ '^\d\+$', i.e. with the ^ and $ anchors in the regexp, instead of just getcmdline() =~ '\d\+'?
