The Reset Button
Each parameter set in the Inspector is equipped with a reset button. A parameter set
might be a filter, or it might be a category of effects or transformations, such as
Transform, Blending, or other items in the Properties tab.
The reset button removes all keyframes applied to all of the parameters within the set
and restores those parameters to their default state.
Animating in the Timeline
When keyframing, it is often very helpful to view your keyframes over time. This lets
you line up keyframes with other important timing elements in your project such as
edit points, sound cues, markers, and even other keyframes. These functions are
available in the Timeline.
In order to view your keyframes in the Timeline, you must first turn on the Show
Keyframes option.
