The link in the footer of the reference currently says Jump to reference. It should say Jump to footnote because not all footnotes are references, they can also be comments etc. That's why the header of the reference preview says footnote as well, see T213907.
I'm not sure it's worth introducing another term here.
- I understand the semantic concern, however I'm assuming that the majority of the footnotes are references/citations, and that comments are an edge case.
- We are already referring to it as a "reference" in the title of the preview (Book reference, Journal reference, etc.) so I think it might be more confusing to then have a button that says "Jump to footnote"...it feels disconnected from the thing you're already looking at.
- As far as I can tell the article section where you are jumping to is called "References" (in English), so there is already the idea that we call these things references, even if sometimes they are just comments
Perhaps in the future we can introduce a "Comment" type/category in VE, and then use that here.
Also, regarding T213907, it was unclear to me that we were agreeing to use the term "Footnote" in the title when there is no type specified, e.g.
I think also in this case it makes sense to use the word "Reference".
