Horizontal Zoom on Audacity 2.2.2

Is there any way to cause Audacity to zoom with the mouse wheel WITHOUT having to press the control key? That’s the way zoom works on Adobe Audition, and I would LOVE to have that feature on Audacity. It’s the only editor I use now, and it’s fantastic! Assuming there is not a way to do this zoom, please consider this post as a new feature request.

You can’t just use the mouse wheel on its own, because that scrolls vertically when you have multiple tracks.
You can click on the zoom buttons (http://manual.audacityteam.org/man/edit_toolbar.html#zoom_in)
You can also select a part that you want to zoom in on, then click the “Zoom to Selection” button (shown on the same page).
