sammy.js - How to customize the mapNav() function in Durandal SPA -

I use the following in the Hot Towel SPA template

  router.ManPoint (' description' ); Router.Manavan ('Home')   
 How do I provide it if I just want to override the name of the route name (to appear in the navigation bar)?  
 I found this example  
  router.mempen ({url: /#\/user\/maintain(#.+)?/, module id: "void / user / Maintain ", name:" maintain property ", hash:" # / user / retaining "  
});  
 Do I need to provide all other parameters to modify the name property?  
 Cheers 
 
 I believe you can call the method, thus specify what you want as follows To override:  
  router.mempen ({url: 'description', name: 'description'}); Router.mapNav ({url: 'home', name: 'awesome home'});
