The Waveform Preview shows you the overall effects of your modifier over
time. The horizontal axis is time, as represented by the keyframe timeline.
The vertical axis is the value you are modifying, as represented by the value
bar.

The Keyframe Timeline

Just above the Waveform Preview, and below the slide preview, is the
Keyframe Timeline. This works just like the timeline you see when you are
setting up any other effects. You can see each keyframe within the layer,
plus the total slide time and transition time.

These values relate directly to the Waveform Preview. The left side of the
Waveform Preview is the start of the slide, and as you move right, you
move through time until you reach the end of the slide on the far right. This
is also why modifiers are about time – the wave makes changes over the
time of the slide. The keyframe timeline here shows you exactly where
those changes will happen.

If you click and drag below the middle bar of the keyframe timeline, you’ll
see a red triangle and time counter appear. As you drag, the preview will
show you the state of the show at that point in time. This type of
previewing, called ‘scrubbing,’ is very useful for quickly checking changes.
