When I was talking about settings I was refering to settings for the hardware specific device
drivers, not Windows 7 itself. (Sorry I wasn't more clear)
As far as I know, there it nothing built into Windows 7 to be able to send keystrokes automatically. However, I'm sure a program could be found to do that.
I believe that to simulate the Fn+F7 key combination you should be able to send Scroll Lock+F7. This is because there is no defined windows virtual key code for Fn and some laptops obey the scroll lock key as if it were the Fn key.
