You can animate an object so that when it is selected, it writes a value to the registry. Common uses for this type of animation include applying different filters to embedded lists when an object is selected, and displaying different layers when an object is selected.
When animating an object to write a value to the registry, you need to set the PickType to 8 (for Registry) and you need to define the values that are to be written to the registry in the PickParam expression.
For information on animations that use the registry pick action, seeLocal Variables (Registry Key Settings).
