 ### Bibliography Actions
 - `⇧ + ↵`: Reveal the entry in Zotero, neovim, BibDesk, VS Code, or Sublime, depending on the setting in the workflow configuration.
 - `⌘⌥ + ↵`: Paste the full bibliographic entry in the APA 6th Style (requires [Pandoc](https://pandoc.org/installing.html)).
-- `⌘ + L`: Preview the (unabridged) title, abstract, and list of keywords in Large Type.
+- `⌘ + L`: Preview the (unabridged) title, abstract, and list of keywords in Large type.
 - `⌘fn + ↵`: Delete the entry from the BibTeX library. (⚠️ This feature is untested with BibTeX files created with apps other than BibDesk and Bookends. [Create an issue](https://github.com/chrisgrieser/alfred-bibtex-citation-picker/issues) for problems with other apps.)
 - `universal action` or `hotkey`: Uses the selected __DOI__, __ISBN__, or __URL containing a DOI__ to add a new entry to the library.
 	- *Experimental:* A second universal action can be used to parse & add a bibliographic entry. Requires [anystyle](https://github.com/inukshuk/anystyle).
-	- The new entry is added to your library, with a correctly formatted and unique citekey. Afterward, the entry is opened in the app specified in `open_entries_in`.
+	- The new entry is added to your library, with a correctly formatted and unique citekey. Afterward, the entry is opened.
+- `file action`: Use the "Add Entry and Auto-file" action on a PDF file that includes a DOI. The DOI is automatically retrieved from the PDF, the entry added to the library, and the PDF auto-filed (see [PDF Management Actions](#pdf-management-actions)). Requires [pdfgrep](https://pdfgrep.org/).
 
 > __Note__  
 > Adding or removing entries does __not__ work with the [BetterBibTeX Zotero Plugin](https://retorque.re/zotero-better-bibtex/) since the plugin only does a one-way-sync (Zotero ➞ BibTeX file), meaning any changes to the `.bib` file are not reflected in Zotero.
