 =Bibtex-actions= also preserves the history of your selections (see caveat below about multiple candidate selection though), which are also accessible in your completion UI, but by using =M-p=.
 You can save this history across sessions by adding =bibtex-actions-history= to =savehist-additional-variables=.

-By default, =bibtex-actions= will, assuming you are using =orderless= or =prescient= to filter candidates, pre-filter entries for the following commands.
-
-1. =bibtex-actions-open=: pre-narrows the list to those which have associated pdf or links
-2. =bibtex-actions-open-link=: pre-narrows the list to those which have associated links
-3. =bibtex-actions-open-pdf=: -pre-narrows the list to those which have associated pdf(s)

-That is, upon running the command, an =initial-input= value will be inserted to narrow the results. 
-You can also delete that if you prefer to see the full list of candidates.
-
-By default, pre-filtering of =bibtex-actions-open-notes= is off, because the command by default will create a new note if none is available, and therefore it makes sense to have access to your full library. 
-But you can customize this to pre-filter if you prefer.

-If you want to modify those values, or remove them entirely, you can set =bibtex-actions-initial-inputs= like so; in this case turning off pre-filtering for =bibtex-actions-open-pdf=:

-Bibtex-actions uses a cache to speed up library display.
+=Bibtex-actions= uses two caches to speed up library display; one for the global bibliography, and another for local files specific to a buffer.
 This is great for performance, but means the data can become stale if you modify it.
 
-The =bibtex-actions-refresh= command will reload the cache, and you can call this manually. 
+The =bibtex-actions-refresh= command will reload the caches, and you can call this manually.
 You can also call any of the =bibtex-actions= commands with a prefix argument: =C-u M-x bibtex-actions-insert-key=.
 
-Finally, another option is to add =bibtex-completion=-style proactive loading externally by using =filenotify= something like this:
-
-#+BEGIN_SRC emacs-lisp
-  ;; Of course, you could also use `bibtex-completion-bibliography` here, but would need

-You can also extend this to do the same thing for your PDF files, or notes:

-    bibtex-completion-library-path '(change) 'bibtex-actions-refresh)
+(defun gen-bib-cache-idle ()
