Edit Animation Curves with a Lattice?

Is it possible to edit animation curves with a lattice?

Not as I know, but you can activate Proportional Editing (Short key O, middle mouse wheel to change influence range while dragging) for editing a bunch of key frames with influence tapering off.

Thanks! That gives me something to try as a replacement. Also, thanks for telling me what it is activating instead of just the hotkey since I change my hotkeys. I can’t tell you how many times an answer comes in the form of, “Just press O” and it doesn’t work…
