Hi

Would someone be able to tell me if it's possible, and how, to create a mirror of a curve in Graph Editor? 

I have created a transparent model of a lock and have the key sliding out of the keyway pushing the pins up and down to follow the contours of the key.  I would like to simply reverse this to show the key going back into the lock without having to manually run through keyframing every pin, which, while easy, is time consuming.  I can't help feeling that there must be a more efficient way of doing this.

Thanks.
