+** TODO bibtex-actions improvements?
+currently =SPC n b= is bound to a function, but =bibtex-actions= doesn't have a
+main dispatch function like =ivy-bibtex=, rather it has a bunch of different
+ones. Binding the ~bibtex-actions-map~ there would probably be better, but there
+are nontrivial loading order shinanigans happening that make that not straightforward.
