title: Can't detect a Ctrl + Key shortcut on keydown events whenever there's a readonly textbox with focus
body: <p>i thought i solved this problem by myself but it came back to haunt my application so here it goes: </p>
  
  <p>i have the following keydown event handler registered in a form with a couple of disabled and readonly textboxes and they are only simple shortcuts for the buttons:</p>
  
  <pre><code>private void AccountViewForm_KeyDown(object sender, KeyEventArgs e)
  {
      //e.SuppressKeyPress = true;
      //e.Handled = true;
      if (Control.ModifierKeys == Keys.Control &amp;&amp; e.KeyCode == Keys.E &amp;&amp; !isInEditMode)
          btnEditMode_Click(sender, e);
      if (Control.ModifierKeys == Keys.Control &amp;&amp; e.KeyCode == Keys.S &amp;&amp; isInEditMode) btnEditMode_Click(sender, e);
      if (e.KeyCode == Keys.Escape) btnCancel_Click(sender, e);
      if (Control.ModifierKeys == Keys.Control &amp;&amp; e.KeyCode == Keys.W) Close();
  }
  </code></pre>
  
  <p>the form has KeyPreview set to true but whenever a readonly textbox has focus and i press Ctrl + E i can't get "Control.ModifierKeys == Keys.Control" and "e.KeyCode == Keys.E" to be both true at the same time. What is really strange is that Ctrl + W works. Anyone has any idea what the hell is going on? :(</p>
