g; has been more useful for me than this one. It goes to the most recent change location. I edit a little, then move around in the same file for reference or check signatures and then continue editing by going to previous edit location using g;.

I've always done "undo-redo" which achieves the same, but I guess ; could be used for other purposes.

g; and gv are the two that keep me from using helix more.
