De gustibus non est disputandum.

I've found javadocs enormously helpful when I was learning Java 20 years ago. But then again, I also like man pages and use them a lot.

If I'm looking for option "-e" of the test command, here's what I would do:

    $ man test

and then "/-e". Searching within a document is a commonly required skill in so many situations that I don't even think twice when applying it in man pages.

Of course, you could also just define a bash function for the functionality you're after like so:

    mano() {
        man "$1" | grep -A1 -- "$2"
    }

and then do

    $ mano test -e

or something along those lines.
