Track

A track is an implied path that an Actor can follow throughout an animation.

Spline Tween Track

A track appears as a series of line segments (Tween) or curved (Spline Tween) with small squares along the length of each piece indicating where the Actor will be in each frame of the animation. It all looks very much like a string of beads, where each bead is a frame and the larger beads are keyframes. The above example has 10 frames with 3 keyframes (the purple squares).

A track will only be visible if the Actor has at least two contiguous movement timelines. If the Actor does not move, all the points on its track will be at the same place, and therefore difficult to see!
