Rename action method in ASP.NET MVC

How to rename action method?

To rename the Action method of the controller, we use ActionName attribute to the action method of the controller.

[ActionName("PersonList")]
  public ActionResult Index(string txtKeyword = null)
  {
     return View();
  }

Here, despite that our Action method name is Index, it will be accessible from the browser as PersonList.

Eg.  http://localhost:8888/PersonalDetails/PersonList (assuming that the controller name in which this action method exists is "PersonalDetails".
