Thanks, Tony. My need is very simple, to allow one track on a layer to cross another. I can put zero ohm resistors on the schematic, but (inevitably, I suppose) that restricts the routing of the jumpered track. In other words, without the jumper I could join point C to either point A? or point B, but if a jumper is needed between B and C, point C can only be joined to point B.

If you want to use headers and links, I have schematic symbols for those. Perhaps KiCad even has them in one of its extensive library, I don't know.

Alternatively, use zero Ohm resistors, and add a text note to say what they are for. Do that, as well for links. If they are multiple position links, add a truth table.

I try to put everything on the schematic. That way, nothing gets missed.

Thanks, Robert. I suppose they have to be placed in the schematic exactly where they are needed in the layout, which can make the schematic look very odd.

They are normally in the schematic as zero ohm resistors.?? In the
layout they can be whatever you like, eg pukkka zero ohm resistors
(wire-ended or surface mount), hand-cut wire links, blobs of solder, etc.
