Gnome open location dialog, originally uploaded by markuz.

It is quite usefull, but, where can I configure the key bindings for the gnome open location dialog?? I mean, It nice if I click on the Desktop and press +l then it appears, but it's not the same if I am on any other application.
You can configure the key shortcuts to show the main menu, or to show the run dialog, you can even configure the shortcut to show your home, but, what about this?.
If you know how to do it (on GNOME), please, let me know.
