title: WPF key bindings all keys in passwordbox
body: <p>I have this passwordbox : </p>
  
  <pre><code>&lt;PasswordBox x:Name="textBox1"&gt;
     &lt;PasswordBox.InputBindings&gt;
          &lt;KeyBinding Key="Return" Command="{Binding MyCommand}"/&gt;
     &lt;/PasswordBox.InputBindings&gt;
  &lt;/PasswordBox&gt;
  </code></pre>
  
  <p>I want to bind my command with all keys, and not just enter.</p>
  
  <p>Is it possible?</p>
  
  <p>Thanks.</p>
