          Wow, this editor has support for links to the whole <a href="https://en.wikipedia.org/wiki/World_Wide_Web">world wide web</a>. We tested a lot of URLs and I think you can add *every URL* you want. Isn’t that cool? Let’s try <a href="https://statamic.com/">another one!</a> Yep, seems to work.
        </p>
        <p>
          By default every link will get a [rel="noopener noreferrer nofollow"] attribute <a href="https://web.dev/external-anchors-use-rel-noopener/">for security reasons</a>. It’s configurable though.
        </p>
        <p>
          Ah, and links open in a new tab by default, but that’s also - yes, you’ve guessed it - configurable.
