Not your fault – the reference documentation for nf is actually misleading here.

and for the reference page i have 2 more ideas
-a- i like the header menu from the
https://p5js.org/reference/
so you could just jump directly to the “String Functions” group.
-b- HTML has some more features now,
how about show some “tool tip” when you are over the link?
because, if you NOT know the command nf()
- how can you find it
- why you should click on it.
