As a quick note, if you’re looking at a Drupal form and it says you can use the "Rewrite the output of this field" replacement patterns shown (somewhere) on this page — and you can’t find those replacement patterns on that page — you can find a complete list of them at this drupal.org url.
As an example, if you’re working with a Drupal Node, you can use replacement patterns like these:
[node:author:name] [node:content-type] [node:content-type:name]
- Those are just a few of the many replacement patterns that are available.
- Those replacement patterns won’t work in all places. Most forms only support a limited subset of them.
I was just working on trying to add a style to a Drupal 8 view, and had no idea where the "Rewrite the output of this field" replacement patterns were supposed to be found, and that page helped me find what I needed.
See that URL for many more patterns, and more information.
