title: How can I simulate function key combinations using C#?
body: <p>I was hoping someone could help me with simulating a function key combination in C#, in this case <kbd>FN</kbd> + <kbd>F4</kbd>.</p>
  
  <p>Here's what I'm trying to do... I have an older touchscreen netbook that I recently installed Windows 8 on. It has a swivel screen so you can fold it down and use it like a tablet. Windows 8 runs surprisingly well on it. I had a few minor issues, most of which I was able to work out, but one remains.</p>
  
  <p>When you first power up the netbook or wake it from sleep, the screen is at 30% brightness, and Windows thinks that this is the max setting, so increasing the screen brightness through the normal methods does not work. On my netbook, pressing <kbd>FN</kbd> + <kbd>F4</kbd>, restores the screen to full brightness. This is a minor annoyance though, because I have to swivel the screen back and forth to fix the brightness using the physical keyboard, when I'd like to just leave it in the tablet position and minimize wear and tear.</p>
  
  <p>What I'd like to do is write a little application that runs on start up, and simulates the function key combination, so the brightness is restored automatically. Any suggestions would be greatly appreciated. Thanks.</p>
