wx.CallAfter worked nicely. I bet that'll come in handy in the future, too.

It's not that I don't believe you, but that wasn't the answer I wanted 
to hear, so I figured out a way to do it. :)

Of course, this may be a problem-specific hack, but, by extending the 
AddPage and InsertPage methods to bind EVT_KEY_UP and EVT_KEY_DOWN 
handler methods to all new pages, the Notebook can watch for Cmd 
keystrokes, intercept NavigationKey events, and decide which page to 
show. This probably only works because the pages that I'm adding consist 
of a single Control, but I'm guessing that Notebooks are often used 
liked that. FWIW, I also got tab dragging/re-ordering working.

I posted an example at: http://pyroscope.org/notebook2.py

If anyone cares to look at it, please let me know if there are any 
improvements I can make to the code.

Thanks!
