Windows 7: Hotkey to change brightness

Hi I was wondering if there was a way to bind a key to increase/decrease brightness of my laptop screen.

I can use the regular FN+Fnkey combo but I am using an external USB keyboard so it would be easier to use a non FN key combo.
I tried reading the scan codes of the FN+F6 key but I couldn't get any, so I can't remap it with a tool like AutoHotkey.

Also, since I have the slider thing in Control Panel > Power Options, this seems doable with a software.

Last note. I do not want a 'screen dimmer' program that does not actually dim the LEDs behind the screen.

Thanks for your input!

Hi.

Windows Key + X opens the Mobility Centre.

not here. is this true always or just with laptops/netbooks?

I would imagine it's just for laptops. Are you holding the Windows key down whilst pressing the X key?

Here is a 3rd party app for setting the percentage of brightness on your monitor. I don't usualy reccomend apps but this one seems to be liked by several other members. So if you want to give it a try, I would just suggest that you create a resore point first before using it incase you don't like it you can uninstal it then restore back to before you installed it.
