[Inkscape-user] what file and preference do I change...

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.
