For me, audiobooks present good analogues for both these cases. I never skip lines in a book, but I might increase my reading speed if something is getting repetitive. Audiobooks also let you increase speed, and I often go to 2.5x or even 3x for low-information-content audiobooks. For re-reading, you can skip back 30 seconds to re-listen.
