Mac users: in case you get frustrated by modern disappearing scroll bars, the "appearance" settings in System Settings has different options you might find useful. What they mean:
- "Automatically based on mouse or trackpad" - hides scrollbars if you're using a scrollbar, and displays if you're using a mouse
- "When scrolling" - only shows the scrollbar if you've already started scrolling
- "Always" - always show the scrollbars no matter what
I missed knowing where I was in a document. I missed being able to jump to a specific position with a single click (that's another option in the same control panel). And having to scroll a tiny bit to summon the scroll bars had gotten old.
It is now my policy to always have scroll bars on all the time. I recommend trying it.
