Zoterolens scans Markdown files for possible citationkeys and adds links open then with Zotero. Also a convenient option to immediately open the cited pdf-file.
I recommend using it in combination with an extension such as [Citation Picker for Zotero](https://marketplace.visualstudio.com/items?itemName=mblode.zotero), and/or [Pandoc Citer](https://marketplace.visualstudio.com/items?itemName=notZaki.pandocciter) to be able to easily add citations.
## Features
- CodeLens to open PDF's based on citekey
- CodeLens to select item in Zotero based on citekey
* Possibly use CodeAction instead of Lens: https://code.visualstudio.com/api/language-extensions/programmatic-language-features#possible-actions-on-errors-or-warnings
