In Maya and Unity (A frequent combo) ALT-Middle mouse drags the view in X and Y. But in the editor it wants to zoom in and out. Something that is also done with the scroll wheel, like the aforementioned packages.
Perhaps it's best to also do the ALT-Middle mouse combo to do the same in the shader editor?
I keep trying to stop my self from zooming instead of translating the view.
