Then I realized that the control I dragged from the XIB to the header file was a NSToolbarItem*, not the NSSegmentedControl* I was expecting. How do I get to that inner control? (Hopefully without wasting time making a subclass.)

I just noticed that myself. Is “(NSSegmentedControl *)self.toolbarBackForward.view”, a cast to a (2 layers down) subclass, the way you’re supposed to access the control’s stuff? It looks like a hack, but I’ll take it since it (seemingly) works.
