I find the most detailed manual I can find on a thing and then I skim it, making note of chapter and paragraph headings. 90% of the benefit of a manual is knowing that a thing is possible the other 10% is the manual telling you how that thing is possible. I do the same thing with man pages, I just scan down them, I don't care about the minutiae at that point but it's handy to know.
