title: Global hotkeys with two modifiers
body: <p>I'm trying to register the global hotkeys 'CTRL + SHIFT + 1 - 3' in C# but when I add another modifier (shift) it doesn't work when I'm pressing the second and third one.</p>
  
  <p>Code for registering the hotkeys:</p>
  
  <pre><code>RegisterHotKey(this.Handle, 0, (int)KeyModifier.Shift | (int)KeyModifier.Control, (int)Keys.D1);
  RegisterHotKey(this.Handle, 1, (int)KeyModifier.Shift | (int)KeyModifier.Control, (int)Keys.D2);
  RegisterHotKey(this.Handle, 2, (int)KeyModifier.Shift | (int)KeyModifier.Control, (int)Keys.D3);
  </code></pre>
