I’m just trying out the Mac beta, love the option to work at my iMac!
I got the impression from the tutorial that scrolling with the mouse surface (I’m using a Magic Mouse) would zoom - but I’ve found that I have to be holding the Control key down to get that function. Scrolling with the mouse surface without holding the Control key results in panning. That’s OK by me, just a little unclear in the tutorial video.
However, because I use the mouse in my left hand, and I’m using the Apple wireless keyboard that came with my iMac, I only have a Control key on the left side of the keyboard - which makes holding the Control key while manipulating the mouse awkward. Any chance you can make this a configurable option, so I can pick a different key to enable zoom with scroll?
