If you HAVE a function key, it must be pressed. I have a full row of F (unction) keys. I have a Function key in order for the soft commands to do what I want, so F5, refreshed the page, unless i hold down the fn+F5-then I eject my disk, as
that is what I want my soft function to be. Try F11 - kiosk mode for the browser, fn+F11- goes forward in my browser history!
What do I know?
