Copy Keys Options

In the Animation menu set (F4): Key > Copy Keys >

See also See Copy and paste keys and Cut keys.

Hierarchy: Specifies how a group of keys will be cut from a hierarchy of grouped or parented objects.

Selected: Specifies that the group of keys will include only the animation curves of the currently selected object. Default is on.
Below: 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.

Channels: Specifies the channels (keyable attributes) whose animation curves will be included in the keyset.

All Keyable: Specifies that the keyset will include the animation curves of all keyable attributes of the selected object. Default is on.
From Channel Box: Specifies that the keyset will include the animation curves of only those channels currently selected in the Channel Box. Default is off.

Driven Channels: 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.
Control Points: 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 Key > Copy 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.

Note:
If you select individual CVs and then select Key > Copy with Control Points on, only the animation curves for the selected CVs are copied.
Shapes: 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.
Time Range: Determines the range of keys to be cut or copied. Select from the following options:

All: Cuts or copies all keys for the current object to the clipboard.
Start/End: Cuts or copies all keys between the values you specify in the Start Time to End Time fields.
Time Slider: Cuts or copies all keys within the Playback Start and End range (between the Range Slider's Start and End times in the Time Slider).

Start Time: (Available only when Time range is set to Start/End.) Lets you specify the start of the time range to be cut or copied.
End Time: Lets you specify the end of the time range to be cut or copied.
Method: Specifies whether the keyset will include keys only or keys and animation curve segments (available if Start/End or Time Slider is on).

Keys: Specifies that the keyset will include only keys.
Segments: 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.
Range: Prevents keys that lie at the beginning or end of a selected range of keys or time and keys from being included in the cut or copy operations. Range also causes your animation in the Dope Sheet to shift to accommodate the removal or insertion of keys or time and keys.
