Hi Dan Stillman and thanks for the answer. May I make a feature suggestion then. It would be nice in the Word citing module to have an option to remove the author, without even the need to open the Zotero dialog and as a bonus, it could copy the author name in the clipboard since usually, it is removed from the citation to be included outside the brackets in the main text.
The suppress author option in the regular, quick format dialog is pretty quick to get to via keyboard shortcuts -- I don't think we need something faster (https://www.zotero.org/support/word_processor_plugin_usage). The clipboard idea is interesting, though.
The copy authors feature is a neat idea! Especially if it could incorporate style-based formatting requirements (e.g., all authors versus et al), but that might be too much a call to citeproc for a smooth UX.
Thanks
