Interactive labs can do a great job of teaching skills, but they fell short of teaching understanding. And at some point, it’s faster to read a book to learn, because there’s a reduced need for practice.

Hypertext is better than printed book format, but if you’re just starting with something you need a guide that provides a coherent overview. Also most online documentation are just bad.

Why ctrl+f? You can still have a table of contents and an index with pdf. And the pdf formats support link. And I’d prefer filtering/querying over generation because the latter is always tainted by my prompt. If I type `man unknown_function`, I will get an error, not a generated manual page.
