Can't add in-page link (to local anchor) as a menu item

I've tried to add a link to a local anchor as a menu item to the menu system. I would like to add a "Skip Navigation" link to my site for accessibility purposes. I've added the local anchor in the template system as

  <a id="skipnav" name="skipnav"></a>

I've tried to add a menu item with the target '#skipnav' but alas, this results in a link to HOSTNAME/%23skipnav. Is it possible to add in-page links to the menu system?
