title: make keyword into link automatically, globally
body: <p>is there a way to make a every instance of a word automatically turn into a link?</p>
  
  <p>so for instance, everytime I write "apple", it is automatically formatted to <code>&lt;a href="www.apple.com" class="whatever" target="_blank"&gt;apple&lt;/a&gt;</code></p>
  
  <p>I'm assuming i could use javascript or possibly jquery.</p>
  
  <p>thanks!</p>
