Thank you Richmond. Something very weird happened when I tested your script. It made for an erratic navigation. I was on card 60 when I pressed the up key, and these are the cards that showed with each consecutive press of the up arrow: 59, 58, 58 again, 59, 60, 61, 60, 59, 58, 59, 59 again, 58, 57, 56, 57, 58, 65, 64, 63, 62, etc...

I tested both your script and mine in a different stack. Same results.
