title: Facebook Status Update-Like Autocomplete/Tagging Feature with jQuery
body: <p>I'd like to create a text input like the Facebook status update Publisher. Basically, an input that can activate an tagging/autocomplete feature with a certain key (ex: @), creating tags that act as single characters in the text input (can be deleted with a single backspace), and yet still accept regular text input. Different from Facebook, I'd like to only accept one such "tag" and only accept it at the beginning of the input. </p>
  
  <p>It seems like the most viable option to go about this (using jQuery) is a contenteditable div. However, I have little idea what to do with the jQuery from there. Can anyone help get me started? Thanks.</p>
