Previewing Keyframe Effects

As you work with keyframes, you’ll find that it’s critical to preview your work
often. There are two different ways to preview keyframes from within the
keyframe interface.

Previewing the Entire Slide

As with all previews in the Slide Options window, you can play the preview
at any time. At the bottom of the window, click on the Play icon.

In Three Previews mode, the larger, active preview will playback the slide.
If you're using Two Previews mode, you'll see the playback in the window
on the left. This works great when you want to see how the entire effect
looks from start to finish.

You can stop the playback at any time by clicking on the button again.
But what if you just want to view a particular section of your slide, without
playing the entire slide? That’s a situation where scrubbing is used.

“Scrubbing” Your Work
As you begin using the keyframe timeline to create effects, you may find
that you want to get a quick look at what your effect is doing at some point
in the timeline. You can do this using “scrubbing”.

Scrubbing is an easy way to see what is happening at any point in time.
Scrubbing is used in the main ProShow interface and in the keyframe
timeline. When you scrub, you are controlling the playback by dragging
your mouse. You can start and stop whenever you want, and the speed you
drag determines how fast your show will play.
To scrub your keyframe timeline, click and drag the mouse pointer beneath
the keyframe timeline. This will cause a red time marker to appear. As you
drag the marker, the preview window will display what is happening at that
point on your slide. You'll also see a real-time update showing you the
exact point in time that the marker is highlighting.
