The whole “things” feature [1] is not documented right now, since I was experimenting with them. If we think it’s time we can make the functions public and document them. Personally I think we can wait for a bit longer.

[1] Includes
- treesit-thing-settings
- treesit-thing-definition
- treesit-beginning/end-of-thing
- treesit--things-around
- treesit--thing-sibling/prev/next
- treesit--thing-at
- treesit--navigate-thing

Plus you can pass thing definitions to search functions like treesit-search-forward.
