How do set the selection mode to "all tracks?"

I’m using Audacity 3.7.7. I can’t find any setting that activates multi-track selection. I’m working on a stereo file, so obviously most edits should be applied to both channels.

Thanks for any insight!

Thanks, but I don’t think that addresses my question. When I drag-select a region of a waveform, I want it to be selected on all tracks. For example, if you have a stereo file and you want to cut some silence out; you’d drag-select the silent region and press Delete. Or you want to select a region and adjust its volume on both tracks.

Right now, Audacity only selects material in one of the tracks, regardless of where the cursor is.

Once the region has been selected in on one track, Ctrl+Shift+K to extend that selection to all tracks

Thanks. But… really? After every selection you have to press a three-fingered hotkey to do what every other waveform editor does by default (for good reason)?

Can sync-lock a group of tracks then the selection will be applied to all of them.

Also can also drag the cursor across different tracks …

drag cursor across the tracks, then delete
