Autoscroll text to a specific position?

Hello,

I have a text document which is several pages long and will use scrolling capabilities. This text document will be contained in an external swf. There will be 6 buttons on the main timeline which will all load the external swf with the text document but I would like the text to autoscroll to a specific postion/part of document that relates to that topic/button. Also, i would like the scrollbar to move in relation to position/part of document in case the user stays in the external swf and reads and scrolls through the document. Is this possible? I have searched for a tutorial on this but have found nothing. I have tried different things but nothing has worked.
