When writing notes for research, it is desirable to have link that can open up citation management software with selected references so that we can easily access our personal entries on the citations.
This can be achieved by using the Zutilo add-on. It provides a menu item “Copy selected item links”. The link is in the form of zotero://select/library/items/XXXXXXXX. It is possible to configure the “mime type” for this protocol so it can be opened by xdg-open or a web browser.
