I clearly need to read up on undo management, but purely based on experience with the rest of IB, I find it odd that the default Undo and Redo menu items have actions that are not publicly declared -- at least undo: and redo: are not in NSResponder.h, NSObject.h, or in the documentation.  Those actions are not listed in the Attributes inspector of the default MainMenu.xib, so it seems like *some* sort of special-casing is going on behind the scenes.

I notice there is a little yellow triangle next to the redo: action, but not the undo:, which again strikes me as odd.

I would have guessed you could copy and paste the Undo menu item from some other project, but that didn't work for me.  The pasted menu item had no target or action.

In any case, you have it working now.
