Deletes the current keys.

Opens the Delete Keys Options window. See To delete keys.

Objects

Select one of the following options:

Selected: Deletes keys only from the currently selected objects.
All: Deletes keys for all objects, including objects that you can’t usually select from the scene view (such as construction history nodes).

Hierarchy

Specify how a keyset is deleted from a hierarchy of grouped or parented objects.

Selected: The keyset to be deleted includes only the animation curves of the currently selected object. Default is on.
Below: The keyset to be deleted includes the animation curves of the selected object and all the objects below it in the hierarchy. Default is off.

Channels

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

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

Driven Channels: Specifies that the keyset to be deleted 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 deleted will include all the animation curves of a selected deformable object’s control points. Control points include NURBS control vertices (CVs), polygonal vertices, and lattice points. Default is off.
Shapes: Specifies whether the keyset to be deleted will include the animation curves of a selected object’s shape node as well as its transform node. Typically, when you directly select an object in the workspace (for instance, in the perspective view), what is selected is the object’s transform node. To delete the animation curves of the object’s shape node as well as its transform node, be sure Shapes is on. To delete the animation curves of the transform node only, turn Shapes off. Default is on.

Time Range

Specifies the time range of the keyset’s animation curves.

All: Specifies no limit on the time range.
Start/End: Specifies a time range from Start Time to End Time.
Time Slider: Specifies a time range defined by the Playback Start and End times of the Time Slider.
Start Time: Specifies the start of the time range (available if Start/End is on).
End Time: Specifies the end of the time range (available if Start/End is on).

Help Images

Displays an image in the Delete Keys Options window that illustrates deleting within a specified time range.

Method: Specifies whether the keyset to be deleted 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 to be deleted will include keys and animation curve segments. This is useful when you want to delete 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 delete 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.

Adjustment

Specifies how the keyset is copied to the keys clipboard after it has been deleted (available if Segments is on).

None: Specifies deleting keys within the specified range. If there are keys remaining adjacent to both ends of the deleted area, the animation curve(s) produced will retain the out tangent and in tangent of the key in the cut area.
Collapse: Specifies removing keys within the specified range. Any keys preceding the cut are moved to the start time of the cut area, effectively “shuffling forward” the animation curve to fill the resulting gap.

Connect: Adjusts the keys clipboard curves in value and adjusts the segment of the original curve following the pasted segment. This prevents discontinuity in the animation (available if Collapse is on).
