#430 Find dupes by unique key

[Alexander Wagner]

Hi!

I wrote some script to fetch data from our library catalogue (a bit beyond bibliographic use but for librarians use ;) which results in unique identifiers for the BibTeX key, as I reuse the unique database index.

This results in a very simple and perfect criterion for doublet entries. So it would be great indeed if I could use this as a filter criterion to find doubletts. Maybe this wwould be a valuable feature for a future version.
