Are you ok with selection_mux becoming selectable? Something Charlie 
and I came up with last night when starting the widget transition.

This sounds like a call for the 'type' attribute for classing Charlie 
was suggesting. It's just a matter of: should we apply it generally to 
all widgets (and have types like button), or just to selectables?
