Is it possible to expand select multiple tracks but not all?

The button at the bottom left of the Pattern Editor toggles between only one track expanded or all tracks expanded.

Is there any way to select which tracks you want to be expanded?

Click on the little arrow on the top left of each track. Also reading the manual one time completely will save you a lot of time.

I have been reading large chunks of the manual. It’s the small stuff sometimes that proves the most elusive.

Thank you very much…

The explanation as to how I missed that, is that the arrows disappear when you use the toggle button at the bottom left of the editor to collapse all but one. Still, I was thinking narrowly because the arrows do come up when all the tracks are expanded again.
