.net prevent keyDown on WebBrowser on certain keystrokes
===

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. 

When I perform some keystrokes, such as `Ctrl + O`, instead of doing what I have told to my Form to do on KeyDown events, the WebBrowser handles the event itself. 

I tried to do something with WebBrowser's `previewKeyDown`, but I am not sure what to do. 

Could you help me with that?

Thanks
