Zotero provides LaTeX users with two options for exporting a BibTeX file.
The first is simpler and suitable for users who do not need to make changes to their BibTeX file once generated. The second however enables users to auto-sync their Zotero and BibTeX.
The benefits of this method include being able to keep your .bib file automatically updating as new references are added to the Zotero manager. In the simple method, the user has to re download the .bib file each time they need to add a new reference.
This method also allows the user to give the reference a custom citation key as the simple method auto generates a very long and sometimes cumbersome key that contains a large amount of characters.
