title: How can I add onKeyPress event to react material-ui textfield?
body: <p>I used a <code>TextField</code> from react material-ui. I want to know whether the user has pressed Ctrl+Enter. I have tried using <code>onKeyPress</code> event but got no result. How can I achieve this?</p>
  
  <pre><code>&lt;TextField
      value={this.state.message}
      autoFocus={true}
      hintText='Type your message here'
      onChange={this.onChangeMessage}
      onKeyPress={(event) =&gt; {
          if (event.ctrlKey &amp;&amp; event.keyCode == '13')
              this.sendMessage();
      }}
      multiLine={true}
  /&gt;
  </code></pre>
