title: Extract KeyCode from KeyData
body: <p>How can I extract the KeyCode flag (a <code>System.Windows.Forms.Keys</code> value without modifiers) itself from a <code>System.Windows.Forms.Keys</code> value?</p>
  
  <p>Let's say the <code>Keys</code> has the flags <code>Keys.Control</code>, <code>Keys.Shift</code> and <code>Keys.A</code>. I want to extract the <code>Keys.A</code> flag, but the <code>Keys</code>´s flags (including modifiers) are variable.</p>
