when you read a single passage and already know the site is pure slop (also so cringe):

1. First-class syntactic selection

Being first-class means that it is not an extra or even sidekick; it is the protagonist.

To select the largest syntax node under the cursor, simply press d (Qwerty).

This feature is handy if you ever asked this question:

"How can I select the current expression/function/argument/statement?"

And this works as long as your language is blessed by the Tree-sitter grammarians.
