title: Angularjs tab button
body: <p>Hi! I was wondering how to <strong>use the tab button on the keyboard to call a function</strong>?  Something like this:</p>
  
  <pre><code>&lt;button 
      class="btn btn-primary order-input-add" 
      ui-keypress="{13:'add_plu(order.orderwindow.add_field)'}" 
      ng-click="add_plu(order.orderwindow.add_field)"&gt;Add
  &lt;/button&gt;
  </code></pre>
  
  <p>This code segment allows me to press "enter" to call function <code>"add_plu()"</code>.  This uses angular ui utility library.</p>
  
  <p>Thanks</p>
