c# ProcessCmdKey overload, match generic combination
<p>On some control, I want ProcessCmdKey to return true if the keys pressed by the user were ALT and any letter of the alphabet.</p>

<p>I'm able to return true if the user presses Alt with the following code, but how can I add the condition of a letter also pressed ?</p>

<pre><code>protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
             if ((keyData &amp; Keys.Alt) != 0) {
                  return true;
             }
}
</code></pre>

<p>Thanks.</p>
