You need to set a bookmark "anchor" on the object that you would like to be the bookmark or location you are looking to jump to. It can be just about any object. Click the object and in the bookmark property you can just type the name in of your bookmark. Next you need to reference that bookmark. So if you have a main report page that you want to jump from you need to add an action for that object to go to the new bookmark you created.
In the properties of the object you would like to jump from, go to the actions tab and select the go to bookmark option and just type in the name of the bookmark that you created. When you hover over this object in the report viewer you should get a finger icon similar to when you hover over a link in IE, click it and it should take you to the object that you created the bookmark on.
Hope this helps!
