Is there a hot-key to enable Storyboard panning with mouse in Xcode 4.3?
===

I'm looking for a hot-key, e.g. `spacebar` + `Click 'n drag`, that will enable me to use the mouse to pan Xcode Storyboard.

Obviously I can use the mouse-wheel to pan the storyboard, but it's far more tedious that clicking and dragging it to the exact location I want.

Is there a way to pan the Xcode storyboard with a click-and-drag motion?
