Copying Switch Keyframes

[benecosse]

I have two mouths on two separate characters using exactly the same audio.

How can I copy Switch Keyframes (phonemes) from one switch layer to the other one? I can't seem to get it to work by copying the keyframes then pasting. If it's not possible like this is there a way of exporting (.dat) of one layer and applying it to another as if it was done in Papagayo.

Have you tried to duplicate the layer and then bind it to the head bone of the 2nd character.
