As I often cite multiple sources in my articles here in Kirby, I built a minimal reference management, that lets me simply refer to these sources by a tag in the text. The actual URL of the source is then given at the bottom of the article in a separate section.
To make this process a little simpler, I built a mini tag for Kirby, which allows me to easily reference to sources in multiple places in the text.
(Ref: PM2015) //use small r in ref
(Source: PM2015 url:https://www.mundhenk.org) //use small s in source
You may create links to sources which open in new windows by adding popup:yes or popup:true to your (Source: ) tag.
