He mentions deep work and how distracting jumping around is. If you reference a lot, do you remember what you read or forget it as soon as you use it?

Often I’m copy pasting commands from documentation to terminal one by one as I’m trying new things. Whether I remember them or not doesn’t matter.

That’s the point I’m getting at. You don’t because your workflow isn’t deep work. I just partition a larger screen myself for the same work but I’m interested in slow deep work.
