Editing more than one track simultaneously

Hi

I am sure this is very basic, but it’s something I never picked up, mostly because I didn’t really use the multi-track function until recently, as I was always editing one track.

So I have a few mono tracks (and one linked stereo track) I have been EQing separately, and I need to make some edits to them (deleting sections, etc) but I want the edits to apply to all the tracks, not just one.

How do I do this?

You can click and drag across multiple tracks to make a selection span multiple tracks.
