Review of what you've learned
Sometimes you may want to cite the same reference in multiple places on a page.
To do so, click the button, and select the "Re-use" tab. This will display a list of all the references currently used in the article.
To find the reference you want to re-use, either scroll through the list, or use the "Search within current citations" bar at the top. Clicking on a specific reference will insert it into the article.
Alternatively, you can copy and paste references within, or between, articles you are editing!
