Deleting more than one animation frame

Ok is there really no way to select more than one frame when editing animations? It's nuts, having to click and delete every single frame.

Maybe there is, but I don't know about it.

I just add a new animation and delete the old one ( instead of deleting all or almost all frames one by one ).

And yes, if it isn't us who are nuts and just can't find it, than it is nuts.
