I don’t know about you but I get bugged by empty keyframes in Flash. I often catch myself wasting valuable development time selecting stretches of timeline and clearing empty keyframes.

I suspect that I’m an obsessive compulsive.

Anyway I’ve stumbled upon a delightful cure for my neurosis.

It works in CS3 – simply select a layer and run the command! Hurray!
