Changing the Window Title from CFDIV

I am developing an application that uses a single index.cfm page to populate three (so far) cfdiv areas; one for the header, one for the cfmenu (on the left side) and one for content. I use ColdFusion.navigate to update the content cfdiv but I would like to change the title of the window when the content cfdiv is updated and can't figure out how to do that.
