title: Is it possible to set valueUpdate:'afterkeydown' as the default valueUpdate in Knockout.js?
body: <p>Instead of repeating this setting in every text input?</p>
  
  <p>To be clear, I'm talking about this:</p>
  
  <pre><code>&lt;input type="text" name="email"data-bind="value: email, valueUpdate:'afterkeydown'" /&gt;
  </code></pre>
  
  <p>For 90% of my inputs I prefer this above <code>'change'</code> - the current default.</p>
