How do I hyperlink directly to a section within a Word Document?

[dkackman]

I have the need to provide html hyperlinks on our SharePoint portal that will
open a Word document and go directly to specific section.

I've tried creating anchored links to bookmarks within Word (docx format)
but only get as far as having the document open (with a uri like
http://portal/requirements.docx#anchor) but it doesn't navigate to the
bookmark. Since some of these documents can be quite large, jumping directly
to the use case is important.

Has anyone else successfully done something like this?

Any help is appreciated,
Don
