Can't pan in the simulator

[themightyoarfish]

I'm on a Macbook, and I can zoom by scrolling and rotate by Ctrl-Dragging. However, I can't seem to manage panning the viewport in the simulator. How can this be done?

I assume the mouse wheel is used for this (like in rViz), but this can't be emulated on macOS easily, so it would be nice to have an alternative for mouse-wheel-less laptops.

Any workaround for this? Limits usefulness for dev on macOS quite a lot.
