title: Capturing keystrokes without focus
body: <p>E.g. with winamp (on Windows at least), you can play a game fullscreen with winamp in the background, and use the media buttons* to control the sound. Winamp doesn't need to get focus, allowing the game to continue fullscreen.</p>
  
  <p>I'd prefer to write this in Java but that probably isn't going to work (capturing keystrokes without focus is already difficult in Java afaik), so any C# solution is also fine.</p>
  
  <p>So the basic question is: how to capture keystrokes without focus?</p>
  
  <p>*) I believe the 'back/forward/stop/mail/search/favorites/web/home' buttons are called media buttons, but a better name would be welcome :).</p>
