We need a convenient method to insert links. In reftex you use the keystroke C-c ], which gives you a minibuffer to search the bibtex files from. This function is bound to that same keystroke here [[*org-mode%20/%20reftex%20setup][org-mode / reftex setup]]. This function will append to a cite link if you call it while on a link.

[[https://github.com/tmalsburg/helm-bibtex][helm-bibtex]] is a very cool interface to bibtex files. Out of the box though, it is not super convenient for org-ref. Here, we modify it to make it fit our workflow and extend it where needed.
Let us add keywords as a searchable field.

(setq helm-bibtex-additional-search-fields '(keywords))

Next, we are going to add keywords to the helm interface. This modifies the helm-bibtex function to add our keywords.
