Gnome Launch Box start keys?

Hi there,

I installed gnome launch box today, but I cannot work out how to run it. I can run gnome-launch-box from the terminal and it starts up, but I can't find how to bind it to a key combination. I have looked in gconf, and in the keyboard shortcuts capplet. gnome-launch-box --help does not help either, and there seems to be no man page.

I want it to start on alt+space, in the same way that launch and quicksilver do.

Thanks.

Marc
