At the head of every clip in the timeline is a badge that looks like two arrows with a little popup triangle next to it. Click the badge and that popup menu appears.
The second symbol appears in the project library and in the timeline. It indicates that the project has been shared/exported. That’s what the radiating curves indicate. When you see it as here with the exclamation triangle, that means the project has been altered since it was output.
All the best,
Tom
