How do I add shape keys to the NlA editor in 2.5?

I cant seem to figure out how to be able to edit shapekeys in the NLA editor, It just appears as red. Any help would be amazing.

I see this thread is couple days old, Im not 100% sure about the nla, or what its for, I get this. I hit the I key with the arrow in the 3d window change the loc rot scale , after I move the green time line then change the loc rot… again. and that works. that’s what the graph editor does, so that’s probably not what you wanted.
Im sorry if Im wrong but are not the shape keys in the graph editor?.
Good luck
