Filtering items used in Word citations

Hello
Does anybody know a way to filter out from Zotero just those records which are "attached" to a Word document through citation?
Now I have sorted out sync and combined my libraries, I have a very messy set of duplicate entries with differing metadata. I want to a) get rid of ones not in 'active' use so I maintain one accurate record to link to, and b) dentify where I already have citation-links to multiple copies of the same item, and consolidate.
I have nearly 1000 entries, so I thought the easiest way to approach this would be to filter a 'clean' set to a new Firefox profile and take it from there.
Any help appreciated.
  • That's not possible -
    I see why you would want that, but unfortunately it's highly doubtful that it ever will be possible, bc Zotero doesn't remember which items it has once cited.
