for example if you want to show the details of an author in a specific page and bookmark it you can disable the Ajax functions (e.g. "Open Window" Property in the Ajax tab of the Properties View) and show the item details in the main window of your web browser (instead of a popup window).
Otherwise you can refer to the URL Fragments feature. This feature is useful for the search engines use a set of well-known rules to determine the visibility of a website. One of these rules is to have simple URLs containing the keywords with which the page should be indexed.
In this way you can bookmark a page and reach it by his url that contains "url fragments". For more details refer to this article http://www.webratio.com/learn/learningobject/the-url-fragments
