title: Possible to extend MarkdownDeep / MarkdownDeepEditor in an easy way?
body: <p>I think <a href="/questions/tagged/markdowndeep" class="post-tag" title="show questions tagged 'markdowndeep'" rel="tag">markdowndeep</a> looks promising (<a href="http://www.toptensoftware.com/markdowndeep/" rel="nofollow">www.toptensoftware.com/markdowndeep</a>). But I need a simple way to extend the functionality of it, including <a href="/questions/tagged/markdowndeepeditor" class="post-tag" title="show questions tagged 'markdowndeepeditor'" rel="tag">markdowndeepeditor</a>. I'd like to:</p>
  
  <ul>
  <li>add custom syntax for some custom HTML in the server side code (<a href="/questions/tagged/.net" class="post-tag" title="show questions tagged '.net'" rel="tag">.net</a>)</li>
  <li>dito in the <a href="/questions/tagged/javascript" class="post-tag" title="show questions tagged 'javascript'" rel="tag">javascript</a> code</li>
  <li>make it work in the MarkdownDeepEditor</li>
  <li>perhaps extend the toolbar with my customizations</li>
  </ul>
  
  <p>Two examples is special syntax for non-breaking spaces (<code>&amp;nbsp;</code>) and soft hyphens (<code>&amp;shy;</code>).</p>
  
  <p>Is it possible? Is it easy? How do I do it?</p>
  
  <p>If not. Do you know any other <a href="/questions/tagged/markdown" class="post-tag" title="show questions tagged 'markdown'" rel="tag">markdown</a> implementations that supports .NET + JavaScript + editor with preview?</p>
  
  <p>By the way: Which markdown editor does stackoverflow use these days?</p>
  
  <p>Thanks!</p>
