←/→ slide a reverse-video → along the editable leg; Enter splices the
chosen hop in at the cursor and ⌫ removes the hop to its left, so a route
can be edited anywhere, not just at its end. It opens on the last arrow,
keeping the classic append flow unchanged. Suggestions, the fetch row,
and the "Next hop from" heading all follow the node left of the cursor,
and the fetch-neighbours round trip now resumes at the same position.
