Saving a position on purpose
The jumplist only records jumps, and that’s usually what you want: the big
moves, without every j and w in between. Sometimes, though, you
reach a spot by small steps and know you’ll want to come back to it.
For that, Helix lets you add an entry by hand:
Ctrl-s— save the current position to the jumplist
Nothing visible happens when you press it, but from then on Ctrl-o knows
about that spot.
If your browser intercepts Ctrl-s (most leave it to the editor here, but
not all), the Space-j picker on the next step reaches the same entries
without the chord.
In the checklist below you walk down the file with 14j, which is not a jump,
so without Ctrl-s there would be nothing for Ctrl-o to return to. Save
the position first and Ctrl-o works as expected.
