title: Jquery Chosen: populate Multiple Select with Tab button
body: <p><a href="http://harvesthq.github.com/chosen/" rel="nofollow">http://harvesthq.github.com/chosen/</a></p>
  
  <p>here is the example page and it has Multiple Select input.</p>
  
  <p>When I start typing, it highlights options. On this moment, when I press Tab button focus moves on other input and leaves previous input empty. I want to add new option when user start typing, for example, user typed 'af', 'Afganistan'is highlighted, user press tab button and Afganistan must be added.</p>
  
  <p>I tried to handle tab keypress, and do <code>$(optionid).click()</code> to simulate mouse or enter select, but it doesn't work</p>
