The Timeline
Just below the previews you'll find the Timeline. The Timeline is a visual
representation of the total duration of a slide. This includes slide time and
transition times.

You will always have two points on a timeline, the Starting Position and the
Ending Position. These points in time are numbered sequentially. The
number 1 will always represent the Starting Position; the highest number
will always be the Ending Position.

Each of these points are Keyframes. You'll learn more about keyframes in
chapter 17, but for now, the important thing to know is that a keyframe is
simply a point in time when something happens. In the case of creating
motion, that "thing that happens” can be a pan or zoom, etc.
The Timeline shows you visually where those points in time (keyframes) are
within your slide.

Identify an Active Preview
In addition to the active Preview being larger, when you select a point in
your slide, you'll see a blue indicator line that connects the active preview to
the timeline -this is the Keyframe Selector Ribbon. The Keyframe
Selector Ribbon shows you where you are making changes within your
slide.

In the figure below, you'll see that the ribbon shows us that the active point
we're making changes to is at the very beginning of the slide.
