How do I select notes?

In tutorial #2, Daniel selects notes.

See 2:20.

How does he do that?

When I try to select something, all I manage to do is to drag the score around.

Thanks!

Press H to toggle between “Marquee tool” and “Hand tool”.

Also, holding down SHIFT works as a temporaty toggle between Marquee and Hand tools…
