Set your own, fixed citation keys
You can fix the citation key for a reference by adding the text “bibtex: your citekey” (sans quotes) anywhere in the “extra” field of the reference, or by using biblatexcitekeymy_key. You can generate a fixed citation key by selecting references, right-clicking, and selecting “Generate BibTeX key”.
