Is there a Vim command to undo the last motion, e.g. <count>j or Ctrl-f?

Question

In Vim, if I issue a jump command, e.g. G, then I can put the cursor back where it was before the jump by using Ctrl-o. However, Ctrl-o would not put my cursor back to the previous spot if I issued a movement command like 40j or Ctrl-f, since they don't alter the jump list. Is there a command which will undo movements such as those?

To be clear, I'm not looking for a "manual" answer, such as 40k gets you back from 40j, since such a command is not generically applicable in the way that Ctrl-o works.

Also, if no built-in command does this, then does any plugin do it?

Answer 1

You can override the default motions to provide for that, like this:

" j, k          Store relative line number jumps in the jumplist.
nnoremap <expr> k (v:count > 1 ? "m'" . v:count : '') . 'k'
nnoremap <expr> j (v:count > 1 ? "m'" . v:count : '') . 'j'

There's also the reljump plugin, which implements the same.

However, be careful, because overdoing this will reduce the usefulness of the jump list. For that reason, I would advise against changing Ctrl-F / Ctrl-B.
