You can setup a URL shortcut by going to URL shortcuts under Library.  The application will allow you to manage URL shortcuts for your main domain. 
  1. Select the short name you want to apply to the end of the link.
  2. Select the redirect you would like for the link to go once you enter the short link.
  3. Select Create.

Note: URL shortcuts require the use of the non-secure domain for the redirect to function.  You can redirect to a target URL which is a secure URL, but using your secure domain as a shortcut path will not redirect to the target path.
