Q: Invert Waveform Zoom (Mouse-Scroll)?

I can zoom in on my waveforms using Shift-Option-Scroll, however the zoom feels backwards to me and I want to invert it.
When I roll my scroll the mouse wheel towards me, the waveforms are zoomed-out and become father away from me. If I scroll the wheel away from me, the waveforms get up close. Apple normally promotes the "Natural" way of interacting physically, but this feels counter-intuitive. Is there a preference or text-document I can edit to invert the zoom?

Additionally, I would like to edit the shortcut to just Option-Scroll (and loose the extra Shift button), but I can't find where to edit that either.
