Behavior effects in the keyframe editor
If you open the Keyframe Editor and look at a parameter affected by a behavior, you see a
noneditable curve that represents the behavior’s effect on that parameter. The noneditable curve
(in this example, opacity channel animation that corresponds to the Fade In/Fade Out behavior)
appears in addition to that parameter’s editable curve, which can be used in combination to
keyframe that parameter.

Note: Use the pop-up menu above the Keyframe Editor to select which parameters are displayed
and to create curve sets. For more information on curve sets, see
Create a custom curve view on
page 463.

Use behaviors
Use behaviors overview
You apply standard behaviors to objects in the Canvas, Layers list, or Timeline. You can remove
an applied behavior by selecting it in the Canvas, Layers list, Timeline, or Inspector, and then
pressing Delete.
Parameter behaviors affect a specific parameter of an object (such as position). You apply
Parameter behaviors in the Inspector to the parameter you want to affect or to an object in the
Canvas, Layers list, or Timeline.
Important: Text, Particles, Replicator, Audio, Shape, and Camera behaviors should only be applied
to their namesake objects.
When a behavior is applied 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. 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. For information on trimming the duration of a behavior, see
Trim behaviors on
page 307.
