Parameter Control
Use to select or limit which animation channels are created when using one of the Set Keyframe tools.
Make the your selection in the Parameter Control window before using a Set Keyframe tool, and make sure that the Set Keyframe Options have Channels set to using the Parameter Control settings rather than All.
This can be useful to reduce the number of Static Actions created, and to ensure that some parameters are not accidentally changed.
Parameter Control is an editor window that can be docked, and can stay open while other tools are used.
