[dba-Tech] Dell Inspiron Laptop and wi-fi

I confess that since I've had this lovely machine, it's been tethered to my
desk and hooked to the router with a cable. I have never once tried its
wi-fi capabilities. And now that I need to, I find that I've misplaced the
user guide.

Does anyone know what the magic keystroke might be to enable wi-fi when I
go visit Starbucks or wherever?
