If I drag a Round Rect Button onto the Toolbar, it instantly gets promoted to a UIBarButtonItem (really!), and I can't set "Touch Down" on it, nor can I change the class of it in IB. That's why I'm confused...

If you don't understand how to select the button itself using the design window, then use List View in the nib's main document window and drill down until you find it. m.
Thank you Matt for the clear explanation (and your patience with a noob)! I got access to the button from the List view and set the Touch Down event on the button. It works!
One question though: Taking another poster's suggestion, I placed a UISwitch in the toolbar and set Touch Down on it. It does register, but only for the OFF -> ON transition. Switching it from ON -> OFF doesn't invoke the action method. Should I be using one of the other events to capture both state transitions?
Thanks again!
