title: C#: Getting the correct keys pressed from KeyEventArgs' KeyData
body: <p>I am trapping a <code>KeyDown</code> event and I need to be able to check whether the current keys pressed down are : <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>M</kbd>  ?</p>
  
  <hr>
  
  <p>I know I need to use the <code>e.KeyData</code> from the <code>KeyEventArgs</code>, the <code>Keys</code> enum and something with Enum Flags and bits but I'm not sure on how to check for the combination.</p>
