Another thread this morning reminded me I had a new-Mac-user issue.
When my wife and I started using Macs, I noticed that the right-left arrow key maneuver in Logos did not advance through parallel books. The Pong ping sound was all I got. Manually selecting a book from the Parallel Books menu works, but that's not as fun or fast. So, this morning I opened the Parallel Books menu and clicked about, just to see if the Archie Bunker TV repair method (slap TV on side) would work. Wadyaknow, it started working. I tried a similar tactic on my wife's Mac, but no dice.
I have vision issues, so it's likely I have missed something. On Windows, ti just worked without any additional intervention. Is there some gnostic nod-wink sequence needed to set this up on a Mac (which I just stumbled upon unknowingly on my computer)?
The computers are identical: iMac 24 (M1); macOS Ventura 13.2.1; Logos Desktop 23.2.35.
BTW, the Wiki has Cmd+Arrow for the keyboard shortcut, but 'arrow' only works on my Mac, and neither works on my wife's.
Here's a screenshot of my Mac (the one where it works):
