On the left side of the timeline, in the Patch Panel area, you can find indicators and other tools for working with tracks and versions. 
In the example above, the upper track (version 1 track 2) is highlighted, and therefore selected. To highlight a track and select all clips on the track, click in an empty space in the Patch Panel area for that track.
The track indicators and tools for this track are (from left to right):
