Behaviors versus keyframes
It’s important to understand that behaviors do not add keyframes to the objects or parameters
to which they’re applied. Instead, behaviors generate a range of values that are then applied to
an object’s parameters, animating over the duration of the behavior. Changing the parameters of
a behavior alters the range of values that behavior generates.
Keyframes apply specific values to a parameter. When you apply two or more keyframes with
different values to a parameter, you animate that parameter from the first keyframed value to
the last.
By design, behaviors are most useful for creating generalized, ongoing motion effects. They’re
also extremely useful for creating animated effects that might be too complex or time-
consuming to keyframe manually. Keyframing, in turn, might be more useful for creating specific
animated effects where the parameter you’re adjusting is required to hit a specific value at a
specific time. For more information on using keyframes, see
Keyframing overview on page 439.
The animation created by behaviors can be converted into keyframes. For more information, see
Convert behaviors to keyframes on page 312.

All available behaviors appear in the Library. Selecting the Behaviors category in the category
pane of the sidebar reveals the behavior subcategories (text behaviors have two categories).
Selecting a subcategory reveals all behaviors of that type in the Library stack.
