I'm kind of losing track of details, but two things: First, the current oc-basic has a "follow" function that if point is over a citation-reference (key), and one does "M-x org-open-at-point", the bibtex entry is opened.
Very cool! Similar to my idea to have a configurable capf, could that function be configurable? A couple of people noted, for example, that the preferred choice would be that the actual document be opened. I actually got a PR for exactly this default behavior this past weekend, and bibtex-completion has a function that takes keys and does this. So would be great do something like: (setq org-cite-basic-open bibtex-completion-open-pdf) Second, I completely lose font-locking when using json files. I know you have plans, Nicolas, to add json support, but even without that, shouldn't the citation be highlighted? Bruce
