title: Simulate keyboard event if sender is not in focus and without knowing target window
body: <p>I am trying to create a media player controller that works while running in the background and without knowing if there is any receiver, just like pressing a key on the keyboard like the <code>next track</code> media key.</p>
  
  <p>I have tried using <code>keybd_event</code>, <code>SendInput</code> or <a href="http://inputsimulator.codeplex.com/" rel="nofollow">http://inputsimulator.codeplex.com/</a> but it only wsender window is in focus. </p>
  
  <p>Is there any way to simulate a keyboard press like <code>VK_MEDIA_NEXT_TRACK</code> without having the sender window in focus?</p>
