For a current project, I've been using a physical book as a reference manual for the API I'm working with rather than using the more typical internet search for the function name. And it's actually somewhat surprising how efficient a physical book is!

Sure, there's a lot of efficiency to Ctrl-F a text string and just find all the places in a document. I won't deny that it takes me longer to pull up the index, search for the function name in the index, then flip to the page. But then I can just leave the book open at that page on the desk (or my lap). I never have to Alt-Tab, or fiddle with the location of windows to switch between looking at documentation and looking at the code I'm working on.

This difference was more stark when I was trying to close-read a different specification to ensure that I understood it well enough to make sure a PR implemented it correctly. I needed to have three different parts of the specification open simultaneously to bounce between all of them. With physical paper, that's just a swish of a hand away. With a PDF reader, well, goto that other section, scroll down to the piece I wanted, now goto the first section again and scroll down again and wait what was that back thing again goto and scroll and scroll and goto and descent into insanity. Trying to use multiple windows ameliorates the problem somewhat, but it also takes an inordinate amount of time to set the view up correctly, and I often end up running into the "focus doesn't follow the eye gaze" problem of typing in the wrong window and ruining the view.
