text: Ahh, I'm not sure how easy it is to use the in-browser editor from a tablet. I've just checked and the editor runs OK on Android, but I dont have any Apple devices. The default editor (called iD) has a walkthrough explaining the important concepts when you click the edit button. In this case you just need to click on the footpath, long key press shows a set of icons with the rubbish bin at the bottom. 
  
  The app which people do use for editing on iPhone & iPad is called GoMap. We have a keen walker in Sheffield who has used this from the outset as his only editor.

  PS. If you're walking there is another map based on the same data which shows more walking infrastructure (path furniture such as stiles & kissing gates), rights of way, field boundaries and named walking routes. The same area is shown here: https://map.atownsend.org.uk/maps/map/map.html#zoom=15&lat=53.32195&lon=-1.4087 (presence of field boundaries, stiles etc. is usually good evidence that someone has walked the path : check in the Peak District proper).
