The animated previews help you understand how each behavior works. Although most
previews are self-explanatory, the Parameter category previews show before-and-after
examples of the behavior’s effect on an animated object, with the gear graphic turning red
to show the object after the behavior takes effect. For Simulation behaviors, the red gear
graphic identifies the object that the selected behavior is applied to.
You can apply behaviors from the Library or from the Behaviors pop-up menu in the toolbar.

Intro to applying behaviors in Motion
Most behaviors are applied to objects in the canvas, Layers list, or Timeline. However, the
Parameter category of behaviors are applied in the Inspector to a specific parameter you
want to animate.
Important: Text, Particles, Replicator, Audio, Shape, and Camera behaviors should only be
applied to their namesake objects.
When you apply a behavior to an object, the object parameters affected by that behavior
are animated based on the behavior’s default settings. For example, if you apply the
Gravity behavior to an object in the canvas, that object’s position is animated and it moves
down, according to the Gravity behavior’s default setting. In most cases, a behavior’s
duration is the Timeline duration of the object to which it is applied (the length of the bar
in the Timeline track area). For example, if you apply a Spin behavior to an object that
begins at frame 20 and ends at frame 300, the Spin behavior’s duration is also frame 20
to frame 300.
Not all behaviors automatically apply motion to an object. Some behaviors, such as Throw,
require you to set the throw velocity before the object is “thrown.” Other behaviors, such
as Orbit Around, require a source object to act as the central object for other objects to
move around.
In addition to applying behaviors to objects, you can apply behaviors to groups in the
Layers list or Timeline. Depending on the applied behavior, all objects nested in that group
are affected in one of two ways: as if they were a single object or as individual elements.
