Next, navigate to the 'Better BibTex' icon in the toolbar. Navigate to the 'Citation keys' tab, open the 'QuickCopy/drag-and-drop citation area' and select Cite Keys'. This commands Zotero to populate the bibliography file with cite keys that can be included in the LaTeX document. You can change the 'Citation key format' if desired, but the default '[auth][shorttitle][year]' should work just fine under normal use cases.
