xsi 5: IK to FK

Is there a way to transfer the IK animation into FK.. and then tweak the FK..
My idea is to sketch quickly the animation with IK then transform it to FK and create all the follow through and wip actions with FK..
How can I do it in XSI?
Thank You

There is a handy tool called Key All Bone Rotations.
You can find it in Animate/Create/Skeleton/Key All Bone Rotations

Here is how I use it:
I mapped a hotkey to it.
Then I just move the IK effector and press the hotkey for Key All Bone Rotations. So all the bones rotations in the chain are keyed. And I don't even have to make the IK animation. I can see directly the FK motion.
It's a handy way to position the hand with IK effector while animating in FK mode.
Hope it helps.
Cheers!
