How do I reference a paragraph in Pages 5? How do I create text like "See 'paragraph' on page n"? Where paragraph could be a heading or a figure etc.

Obviously, I mean where page n is determined by Pages, as with other word processing programs.
This is currently not possible. You'll have to enter the page number manually. You can use comments to remind yourself where these occur and to update them.
