How to clear multi-track selection?

[Fotu]

Very noob question, but can't find it in the manual, via experimentation, etc:
Scenario:
* Reason 9.5 on Windows
* Multiple tracks in a song
* Not in Edit Mode
* Right-click on a track header and choose 'Select All' from the edit menu
* All tracks get highlighted indicating they are all selected.

But now how do I clear this selection of all tracks? (Otherwise subsequent track-level actions like delete will act on all tracks)? I can't seem to find a place to click or double-click, nor an edit command to clear the select-all.

shift+click on a track

Thanks Ahornberg! Indeed shift-click or ctrl-click will eventually get back to smaller groups or a single track selection.
