Andreas Esau posted a new addon to help you animate using shapekey drivers.
Hey there, this is a small addon I have written for Blender. This addon makes the task to connect shapekey driver to bones super fast and super easy! Creating driver and connecting them to your bones always was a tedious task and I really hated it, thats the reason why I have written this small addon operator. Feel free to download and use it.
