Duplicate duplicates all tracks even if only one is selected?

Maybe I’m selecting tracks wrong, but I thought I’d just click on one, and it’s highlighted by a yellow border… and then if I hit duplicate – all the tracks are duplicated. Any idea what I’m doing wrong? Thanks.

Isn’t there a SELECT button over on the lower left of the track? I think that’s the magic one.

The yellow border indicates that a track has focus.

The track that has focus is the track that accepts any command whose name includes “focused track”. These commands include commands such as “Close focused track” (Shift + C), “Mute/Unmute focused track” (Shift + U) and “Toggle focused track” (RETURN or Enter, which toggles whether the focused track is selected or not).
Track focus is used to select audio and to extend or move the selection region into other tracks using the keyboard.

Selected tracks are indicated by a change in shading of the track control panel and the waveform area.
Multiple tracks can be selected, but only one track can have focus.
