armature proxy does not show up in graph editor

Hi,
I’m making an animation that uses links (append) to the models which are in separate Blend files. I would like to tweak the motion graph of a model proxy, but the proxy’s graph does not show up in the graph editor. Any suggestions? Thanks.

Never mind – I was trying to see NLA Editor data strips in the Graph Editor. I forgot those are frozen. Oops. Sorry.
