         Opens the Snap
               Keys Options window. See 
                     To snap keys.
         
         Objects
            Select one of the following
               options:
            
            - Selected 
- 
                  Specifies to snap keys
                        only from the currently selected objects.
                      
- All
- 
                  Specifies to snap keys
                        on all objects, including objects that you can’t usually select
                        from the scene view (such as construction history nodes).
                      
Hierarchy
            Specifies how keys in
               the selected keyset will be snapped from a hierarchy of grouped
               or parented objects.
            
            - Selected
- 
                  Specifies that the keys
                        to be snapped will include only the keys on the currently selected
                        object. Default is on.
                      
- Below
- 
                  Specifies that the keys
                        to be snapped will include the keys on the selected object and all
                        the objects below it in the hierarchy. Default is off.
                      
Channels
            Specifies the channels (keyable attributes) whose
               keys will be snapped.
            
            - 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
                     to be snapped 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 snapped 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 snapped 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 snap
                     the animation curves of the object’s shape node as well as its transform
                     node, be sure Shapes is on. To snap 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).
                      
Snap 
            
            Select one of the following
               options:
            
            - Times
- 
                  Snaps keys along the
                        time axis only. This is the default setting.
                      
- Values
- 
                  Snaps keys along the
                        value axis only.
                      
- Both
- 
                  Snaps keys along both
                        the time and value axes.
                      
- Snap Times to Multiple of
- 
               This value defines multiples
                     of the time unit to snap to.
                   
- Snap Values to Multiple of
- 
               This value defines multiples
                     of whole number attribute values to snap to.
