to adjust the default zoom level on the default document opened by inkscape? 

I've been playing with some settings in the default.svg file.  I managed to get it to open a 500 x 500 px page with no boarder.  I'd like to have the page zoomed to fit the screen.  I see a setting of inkscape:zoom = "0.35" but that doesn't seem to work as adjust in the zoom level in inkscape has no effect on this value in the xml editor. 

Thanks for the help in advance.
