menu or navigation tag

Extremely newbie, here.
I can’t seem to find a menu or navigation tag anywhere.
I’m beginning to think there isn’t one.
Does ModX have a tag that will automatically create links in the sidebar as pages are created?
Or do I have to manually create a link every time I create a page?
Thanks,
Cway

Wayfinder. The snippet should already be installed if you installed the default content.
