Select the target of the link and make it a bookmark - select bookmarks in the menu and give it a distinct name, for example "section_b".
Then select the text that will become the hyperlink and select the hyperlinks dialog from the menus, in the section for "target in document" select the icon - it will pop up a dialog window with a list of items, including the current bookmarks. Select the created bookmark, in this example "section_b".
Newer versions of OpenOffice require you to hold down CTRL to allow clicking a link.
Links can go to other OpenOffice documents as well.
