Saving Custom Behaviors
As mentioned earlier, a very powerful feature is the ability to save nearly anything to
the Library for later use, such as customized behaviors, filters, generators, particle
emitters, and so on. In this section, save the behaviors applied to the circleText object as
a custom behavior. Although you can save the behaviors in any Library category, this
example uses the Favorites category.
To save a custom behavior:
1 In the Library, select the Favorites category.
2 In the Layers tab, Shift-select the Spin and Grow/Shrink behaviors.
3 Drag the behaviors to the Library stack and hold the mouse button down.
