Walking back and forward
Two keys walk the jumplist:
Ctrl-o— jump back to the previous positionCtrl-i— jump forward again
Every Ctrl-o takes you one entry further into the past, and Ctrl-i undoes
that one entry at a time. Pressing Ctrl-o for the first time also records
where you are right now, so Ctrl-i can always bring you all the way back to
where you started.
To a terminal, Tab and Ctrl-i are literally the same key, so Tab works
for jumping forward as well — some people find it easier to reach.
The checklist below seeds the jumplist with three goto-line jumps, then rides
Ctrl-o and Ctrl-i back and forward through those entries. Keep an eye
on the line number at the right end of the statusline as you go.
