Specifies that the group of keys will include the animation curves of the selected object and all the objects below it in the hierarchy. The keys clipboard keeps track of the hierarchical relationships of the keys and animation curves in the keyset. You can paste the keyset to a hierarchy of objects whose hierarchical structure is the same as the one the keyset was cut from. If the hierarchical structure is not the same, Maya will paste the keys in a way that best matches the keyset’s hierarchical relationships to the hierarchical structure of the objects. Default is off.
Specifies that the keyset will include any driven keys. The driven keys enable the values of keyable attributes (channels) to be driven by the values of other attributes. See Driven keys. Default is off.
Specifies whether the keyset to be copied includes all the animation curves of the selected deformable object’s control points. Control points include NURBS control vertices (CVs), polygonal vertices, and lattice points. For instance, if you select a NURBS surface’s transform node and then select Edit > Keys > Copy Keys with the Control Points option on, the animation curves for the surface’s CVs will be cut along with the animation curves for the surface’s translation, rotation, scaling, and so on. Turning Control Points on is useful when you are doing a lot of animation at the control point level (for instance, CV-intensive animation) and don’t want to have to select each control point. Control Points is off by default.
If you select individual CVs and then select Edit > Keys > Copy Keys with Control Points on, only the animation curves for the selected CVs are copied.
Specifies whether the keys will include the animation curves of a selected object’s shape node as well as its transform node. Typically, when you select an object in the workspace, the object’s transform node is selected. To cut the animation curves of the object’s shape node as well as its transform node, turn on Shapes. To cut the animation curves of the transform node only, turn Shapes off. Default is on.
Specifies that the keyset will include keys and animation curve segments. This is useful when you want to cut the segments of animation curves that lie between keys. For instance, you might not have any keys in the time range you’ve selected, but you want to cut the animation curve action in the time range. To preserve the shape of the animation curve segments, Maya will create keys at the time range’s start and end times if keys do not already exist at those times.
