title: What are the options for (keyup) in Angular2?
body: <p>The following works great when the <strong>enter</strong> key is released. <strong>What other options are available for the <code>keyup</code> in addition to <code>keyup.enter</code>?</strong></p>
  
  <pre><code>&lt;input #inputstring (keyup.enter)="doSomething(inputstring.value)"/&gt;
  </code></pre>
