What is the deal with the little clocks? Audacity 4.0

Can’t tell if this is a bug or an effect but mid working in a session, suddenly I’m getting these “little clocks” appearing on my tracks in the naming area to the left, and when I select a single track audio it shows up. See screenshots for both.

So … what is this? How do I make it go away? How did I make it show up inadvertently?

thx,

Katie

Also moving one track segment now moves all tracks … in spite of the preference to do so being shut off.

You’re using Audacity 3, and these are sync lock clocks. We’ve removed the feature in 4. In 3, you can turn it off in the tracks menu

See this page in the Audacity manual.

ahhhhh!!! I’ve never accidentally clicked that before. Got it. thx!
