yes, you can use a settings map on the top-level {:nextjournal.clerk/visibility {:code :hide :result :hide}} see https://book.clerk.vision/#visibility

so something like

{:nextjournal.clerk/visibility {:code :hide :result :hide}}
1
2
3
{:nextjournal.clerk/visibility {:code :show :result :show}}
42

this will hide the code & results for 1 2 3 and then show 42 (and everything coming after it)

Ah! Thanks! I've been overusing ^ as I thought it was necessary and adding it to each call to visibility. What does ^ actually do?

it changes the metadata https://clojure.org/reference/reader#_metadata
