Marking parameters is a way of identifying which parameters on a selected object you want to use for a specific animation task, such as keying. By keying only the marked parameters, you can keep the animation information small and specific to the selected object.
Keying transformations (scaling, rotation, and translation) is something that you'll probably do a lot. Because of this, when you activate any of the transformation tools (scale, rotate, or translate) from the Transform panel or by using their hot keys, their corresponding local transformation parameters are automatically marked. For more information on this, see .

Marking sets are lists that are used to remember which parameters are marked on an object (like an absolute path to the marked parameters). This makes it easy to work with hierarchies because each object within that structure can have its own marking set, such as a set or marked rotation parameters for bones, or a set of marked translation parameters for effectors.
Marking sets are actually custom parameter sets with proxy parameters (linked copies) for the marked parameters in them. As a result, they are saved as properties of each object, as are standard custom parameter sets. See for more info about custom parameter sets.
When you create a marking set, you store the current marked parameters in a set for each selected object. If a marking set already exists for the object, it is replaced by the new set; that is, you can have only one marking set per object at a time.
Choose Animation Parameters Activate Marking Set (or press Ctrl+M) to activate the marking set, then set a key in any way as described for keying marked parameters (see ). This sets keys on only the parameters in the active marking set.
Choose Animation Set Key Using Marking Set. This sets a key at the current frame using the marking set without first activating it or changing the currently marked parameters. It searches all nodes in the selection for custom parameter sets named "MarkingSet" and then sets keys on their contents.
Choose Animation Set Branch Key (or press Alt+K). This searches all nodes of the selected object and its children for custom parameter sets named "MarkingSet" and keys all the marking sets it finds. This is useful for working with characters and other hierarchies.
