Undo when working with keyframes

No.

But you can delete individual keyframe nodes. (not ideal)

Unfortunately this is not possible. Hopefully in 5.0.

Does anyone know if it is possible to undo a change when working with keyframes? For example with 3DPIP when deleting a keyframe by mistake? At this moment I know of no other way then to press cancel and start again from where I left, but this is a bit of a struggle.
