I need a 'pulsing' light in my scene, so I have animated a material's emmission strength over a few frames and keyframed that with 'I'.

I want that infinitely repeating using f-curve since I need it pulsing throughout any length of animation, but f-curve is disabled in the Dope Sheet (see attached), and I see nothing in the Graph editor.

(In the Dope Sheet I select the keyframes and 'shift-E -> f-curve' but it does nothing)

Anyone seen this before? Thanks
