title: Markdown live preview in Textarea?
body: <p>Are there any Javascript Markdown editing toolbars or libraries that show the live preview within the textarea and hide the formatting marks (**, ___ etc), similar to <a href="http://tinymce.moxiecode.com/examples/full.php" rel="nofollow noreferrer">TinyMCE's</a> implementation?</p>
  
  <p>If not, how would I go about implementing this in jQuery?</p>
  
  <p>I'm currently using <a href="http://markitup.jaysalvat.com/" rel="nofollow noreferrer">MarkItUp</a>, which only shows the preview <strong>after</strong> the textarea, or in a pop-up.</p>
  
  <p><a href="https://stackoverflow.com/questions/1617093/displaying-markdown-in-my-textarea">This post</a> refering to 'BlueCloth' sounds close, but although im interested in general implementation a RoR version isn't very useful at this stage (I'm using Python/Zope).</p>
  
  <p>I'm aware that most of the beauty of Markdown is it's simple text formatting characters, but the site in question is fairly non-technical and I'm largely using the Markdown Python library for it's 'evil' html stipping abilities.</p>
  
  <p>UPDATE: In response to comments, I suppose I'd be happy for the formatting marks to display if <em>typed</em>, but not if the toolbar is used (i.e. I'm assuming GUI users are less technical users). </p>
  
  <p>Or, other toolbars have a 'source' view, which might be an option.</p>
