In the top level menu, you will find Transport > Auto Play
Also,
because when you skip forwards or backwards you don’t expect playback to stop.
just a general recommendation to use first person (“I don’t expect”) for statements like this. After 20+ years in DAW land, I can assure you that what people expect is definitely not just one thing.
Interesting. I just tried on the Windows version and playback doesn’t stop when skipping/nudging the playhead with the arrow keys, whether Auto Play is turned on or off. Is there any other setting that affects this?
