If I want to move the user view in Mac, I can do it by pressing Alt + Shift + LeftMouseButton. Note that I just have a trackpad, not a mouse. Anyway, the problem is that this way I can just move along two axes. To make this clear I took a video, which you can see here.
Like you see in the video I can only move just along the Y and Z axes, not along the X axis. If I wanted to move the user view in order to look at the back of the cube. I had first to rotate the camera and then move the visual again, which is doable but it's not fast/comfortable at all. I need a way (possibly a shortcut) to move the user view along the X axis.
