copying sections from multiple tracks

Is there a way to select PART of MULTIPLE TRACKS? When I try to do that, it won’t let me select and scroll up (or down). I select a few tracks with my mouse, but I need to select many more above, but the cursor won’t scroll up and select the tracks.

Very frustrating. Can you please help?

Thank you so much!!

It works for me.
Which version of Audacity are you using?
