Move cursor and limit characters using JQUERY

The code below is working but needs to be modified to move a cursor to the newly created textbox so that a user can continue typing when a maximum of 40 characters is reached in each textbox.Also to limit the number of characters when they reach 1000 and be able to display all typed characters in another textbox.(EventNature).

ViewBag.Title = "Home Page";

}

@Html.TextArea("EventNature",new { maxlength=50, // or other value

style = "width: 200px; height: 100px;" })

@if (ViewBag.Message != null)

{

}
