Just like you’d find in other parts of the program, at the bottom of the
modifier window you'll find several buttons. These buttons let you control
the preview and access additional options.

Using the Play button here, you can preview your slide to see what impact
your modifier has. The Options button opens a menu allowing you to see
additional value settings in the Waveform Preview. The Copy button lets
you copy modifiers between keyframes and settings.
The keyframe timeline also provides a convenient way to preview, by
clicking and dragging in the bottom of the keyframe area, you can ‘scrub'
the preview. Just below the Waveform Preview are a set of checkboxes
that allow you to control what is shown on the graph.

We will go into much more detail on the Waveform Preview as you learn
how to configure and control your modifiers. For now, let’s move on to the
different kinds of actions you can create within a modifier.

Creating Actions for Modifiers

So far, we know that a modifier changes the value you create it for, and that
within each modifier you can create multiple actions. These actions are
what make the modifier work, and create the effects you see. You can
combine actions together to get different results, but before you do that,
it’s best to understand exactly what you can configure for each action. Let’s
start with the types of actions you can choose.

Each action consists of two different things you can configure: type and
variable amount. The type of action determines how this action affects the
overall modifier. The amount is how much should be applied by the action.
For example, if you specify an action of ‘Add 5’, the type is ‘add’ and the
amount is 5. We’ll go into more detail about types and variable amounts
below.
