### Steal, and keep stealing

Note: If you decide your module should have one of those button links you see at the top right of a bunch of pages in Drupal's administration, you *don't even need to know* that they are called "Action Links" and find a tutorial on making them.  You can just go look in the code of a module you know has them, grep for the label, and steal the code around it.

![grep -nHIRs "Add content block" web/core/ with a half-dozen results, including web/core/modules/block_content/block_content.links.action.yml:9 and a bunch of results in tests.](images/add-content-block-action-link.png)

Note: Grep.  Even when i am fully using an IDE for everything else, i grep in the regular command line when looking for text in a file.  This habit is probably fueled more by failing to tell the IDE to index Drupal core and contrib modules more than anything else.
