What is the equivalent of MSO outline mode in OpenOffice.org?

Open the Navigator to have a little of this functionality, although the Navigator is closer in functionality to MSO's Document Map. The Navigator can be opened by pressing F5 or clicking the Navigator icon on the standard toolbar, or from Writer's menu bar: Edit > Navigator (in OOo versions before 3.1) or View > Navigator in OOo 3.1 and later.

This allows basic navigation of the header structure in the document, but does not provide the tools for preparing a document in the structured way that MSO's outline mode supports. To vote for the addition of this feature to OpenOffice.org, see bug 3959.
