Is there a hotkey or something that will bring the object scene view into the tool state of the display SOP of the selected object?

For instance, creating a curve object from the shelf tool, you're in curve-edit mode in the object view. When you stop building the curve and go do something else, you have to go into the SOP context to edit the curve again.

What I'd like to be able to do is select my curve object in the object view, then edit that curve SOP in the object view, same as if I'd used the shelf tool to construct a new one. If the curve SOP is the only SOP in the curve object, this should be easy, right?

cheers,
