Not far from where I live there is an [abandoned railway][1]. But a path also follows this railway exactly. For the eastern half, I can just about highlight the underlying (cycle) path because the ways diverge slightly at one end. But for the western half I can't see how to highlight the underlying path to edit it (I want to add 'bicyles=yes')- or even if such a path exists on OSM! A search through other answers suggests using '/' in Potlatch, but the potlatch editor option seems to have disappeared. I'm using the standard editor, tried on Firefox and Chrome. [later] there is a (footpath) underlying the railway, I can see it on OpenCycleMap. But I can't see it on OSM. [1]: https://www.openstreetmap.org/way/25818737#map=15/50.2533/-5.0565
