How do I turn off my laptop's back light using a shortcut, or a program in Windows 7?

I have a Gateway NV59 and can press Fn + F8 to blacken the screen. At night, while watching a movie on my other monitor, it is a pain to try and find the right keys as they are far apart and hard to see with my lights off. Since I like to always be efficient, I would like to use my mouse instead of go from mouse, to keyboard, to mouse again (to hit play).

Volumouse, from NirSoft, can also change the brightness of the screen, along with of course changing the volume.

It's explained on this post: How To Dim or Increase The Brightness of Laptop or Notebook LCD Screen

You can also change the brightness using a slider with Desktop Lighter, but I don't know if it works with Windows 7:

I cannot test it as I don't have a laptop running Windows 7 but you could try Display Brightness Console. More info at the bottom of this page about the Display Brightness Gadget:

To use the console app, the following parameters are allowed:

  • DisplayBrightnessConsole.exe

    This will return the current brightness level.

  • DisplayBrightnessConsole.exe -getlevels

    This will return all possible brightness levels accepted by the display, separated by a new line.

  • DisplayBrightnessConsole.exe 20 (or some other brightness level number)

    This will set the brightness level of the display to the parameter given, in this case, 20.

Almost, but I want to be able to do it with one click. Is there a way I could make a shortcut to this program, and then use switches like -dim to do it? – Tanner Collin Sep 2 '10 at 6:56
Edited my post with yet one more tool :-) . If it works, you can create shortcuts to it with various brightness levels. – Snark Sep 2 '10 at 8:28
Those all adjust the brightness, they don’t actually turn the backlight off. ☹ – Synetech Jan 2 '13 at 17:22

I'm currently using only OS X until someone helps me with this problem, but as I recall it should be under Control Panel > Display > Adjust Brightness (on the left column).
