Change scroll height in an Inspector

I'm trying to create a tool that will need to find a term in an email (opened in inspector view) and highlight the term. If the term found is not in the currently displayed portion of the email, I need to scroll further down in the email so the selected term is visible to the user.

I have not been able to find a function or property to control the scroll height in the documentation. Does anyone know of a way to do this?
Also - if there is a way to control the scroll height - will I be able to relate the needed height to the specified term's location in the email?

Thanks.
