title: using URL hashes in javascript AND anchors
body: <p>We're using URL hashes in some places in our app to filter the display, e.g. <code>#highlight=free</code> will highlight our free content. We use javascript to process the hash, listen to hash changes. All works great.</p>
  
  <p>We're wondering however about the best way to mix it with "real" HTML anchor links. i.e. links that point to a specific html id on the page, e.g. <code>#chapter-5</code>.</p>
  
  <p>Should we implement jumping to the right place using javascript and stop relying on the default browser behaviour? for example, link to <code>#chapter=chapter-5&amp;highlight=free</code> and handle both filter and anchor in javascript? Or is there a safe/standard way to "mix" anchors and custom hashes?</p>
