Simulating keyboard shortcuts in textbox_keydown event to handle?
<p>I am trying to simulate keyboard shortcuts such as (Ctrl + A, Ctrl + Shift + X) into a textbox using the keydown event in a textbox but I have a bit of a dilemma. I am using a listbox to log the events that are thrown when it simulates a keyboard shortcut but it runs the event twice. I ask how would I make it so that it only logs into the listbox the shortcut if it only has a modifier key (ctrl, alt, shift, winkey) + an alphanumeric key (a-z 0-9)?</p>

<pre><code>    private void txtShortcut_KeyDown(object sender, KeyEventArgs e)
    {
  // Example key press: Ctrl + A
        if (e.Shift || e.Control || e.Alt)
        {
            string s = (e.Shift ? Keys.ShiftKey.ToString() + " + " : "") + // Shift
    (e.Control ? Keys.ControlKey.ToString() + " + " : "") +  // Control
     (e.Alt ? Keys.Menu.ToString() + " + " : "") +  // Alt (menu)
      e.KeyCode; // Key.

            lbLogger.Items.Add(s);
   // Logger Results:
   // 1) ControlKey + ControlKey
   // 2) ControlKey + A
            // * I'm trying to get it to only post the second line and only log the line
            // when a modifier key + a-z 0-9 key is pressed with it.
        }
    }
</code></pre>

<p>What would be the most efficient way to go upon this process of only logging if a modifier key + an a-z or 0-9 key are pressed? </p>
