title: .net prevent keyDown on WebBrowser on certain keystrokes
body: <p>I write an application in Visual C# using .NET Framework 4.5 (Visual Studio 2012 RC Professional). In this application I have a WebBrowser element. </p>
  
  <p>When I perform some keystrokes, such as <code>Ctrl + O</code>, instead of doing what I have told to my Form to do on KeyDown events, the WebBrowser handles the event itself. </p>
  
  <p>I tried to do something with WebBrowser's <code>previewKeyDown</code>, but I am not sure what to do. </p>
  
  <p>Could you help me with that?</p>
  
  <p>Thanks</p>
