How to pan in Shader Preview windows?

[D.A. Bentley (SuddenPlanet)]

I know I can pan the whole 2D view with Alt+Ctrl and Mouse Drag, but I need to pan the actual shader info/image to see whats beyond the boarder.  Since there doesn't seem to be a way to pan I try zooming out to see the area I want to see, but when I zoom in I can't seem to choose a zoom in point with either of the two icons at the lower left.  What am I missing here?

You aren't missing anything. These 2D previews are unfortunately still pretty limited. There's a concept for how to improve their UI, but not implemented yet. It's in our issue tracker though, so hopefully Matt can tackle it sooner than later.

Thanks!  Glad to hear there is a concept in the works.
