A simple preference checkbox, like that of Photoshop, would allow zooming without having to hold the ALT key. This would be a lot more inclusive, accessible, and, in my opinion, comfortable!
I was going to ask, “how do you scroll vertically and horizontally, then?” But I tried the setting in Photoshop and it looks like the preference checkbox switches the modifier key (option/alt for PS) between zoom and scroll. That’s interesting that you prefer the default behavior of the scroll wheel to be zoom instead of, uh, scroll!
Yes! Basically because scrolling in just one axis in such a sprawling canvas is not as useful as simply holding the mousewheel click and moving the camera to my desired position. I also have a bad case of tendinitis in my left arm/hand that causes me to prefer applications that reduce the requirement of keyboard inputs.
Got it, that makes sense. Voted to add a user preference!
