If they're nested in two different places, they are two different keywords. If you want to assign both to a photo, you have to do two assignments.
Thanks dj. So I cannot have one keyword Giants Causeway that will automatically link to subfolder/category National Trust and a separate subfolder/category UNESCO? Apologies if this seems stupid (I have only started working in digital) what do you mean by two assignments? Thanks.
I've never found a way of doing what you're asking.
For your specific example. My way of dealing with the problem is to treat the 'Giants Causeway' as a location under the hierarchy PLACES> UK>Northern Ireland>Antrim> Bushmills Then apply Unesco and National Trust as separate keywords.
BTW, don't tell everybody it's a world hertiage site or we'll not be able to get into the place for tourists ;-)

If you want the photo to have both keywords, then you have to assign the keyword under UNESCO and then you have to assign the keyword under National Trust.
But I think Ian is on the right track, that's how I would handle it.
I should have added that the reason I use the approach I do is that many locations of photographic interest, will have sub locations or features of interest that I will want to identify. In the case of the Giant's Causeway I list: Giant's Boot, Giant's Organ, Chimney Stacks, Giant's Harp, Giant's, Eyes, Shepherd's Steps and a bunch of other local features under "Giant's Causeway" in my hierarchy (see screenshot). If I have shot of the Giant's Boot I apply that keyword and Lr will automatically apply Giant's Causeway, Bushmills, Causeway Coast, etc right up to PLACES.
Thanks dj and Ian for your comments. I think I will try to place as much as possible within location and then add if necessary, although I am going to try the two assignment approach just to see how it works. Many thanks again.
