	            corresponds to one of the bones in the armature, and each channel has
	            an Action IPO associated with it.  The Action Window provides a means
	            to visualize and Edit all of the IPOs associated with the Action together.

 	            over the left-hand portion of the window, press
	            <B

>XKEY</B

	            there is no undo so perform this operation with care. Also
	            note that deleting an Action channel that contains
	            constraint channels will delete those constraint channels as
	            well.

>&#13;	            If you have an animation that involves constraints and you
	            would like to use it in the game engine (which does not
	            evaluate constraints, and is not covered in this Book), 
			you can bake the Action by pressing
	            the <TT
CLASS="literal"
>BAKE</TT
> button in the Action Window 
			ToolBar.  This will
	            create a new Action in which every frame is a KeyFrame.
	            This Action can be played in the game engine and should
	            display correctly with all constraints removed.  For best
	            results, make sure that all constraint targets are located
	            within the same armature.

>&#13;			You can actually see the Action IPO associated to a bone
			In the IPO Window instead than in the Action Window if you 
			switch to IPO Window (<A
HREF="x6746.html#BSG.CHA.F.S68.112"
>Figure 12</A
>).
	            The Action IPO is a special IPO type that is only applicable to bones.
	            Instead of using Euler angles to encode rotation, Action IPOs use
	            quaternions, which provide better interpolation between Poses.

>&#13;	            Quaternions use a
	            four-component vector.  It is generally difficult and unintuitive 
			to describe the
	            relationships of these quaternion channels to the resulting
	            orientation, but it is often not necessary.  It is best to generate
	            quaternion KeyFrames by manipulating the bones directly, only editing
	            the specific curves to adjust lead-in and lead-out transitions.
