theHtmlWindow.GetChildren() will return a sequence of the child widgets 
of the window.  You can iterate through that sequence and grab the 
values or nearly whatever else you want to do.

You can look at child.__class__ or use isinstance()

Not directly, but you can catch the link clicked events to know when the 
page is being left by some means other than your buttons.
