You can easily maintain the jump lines of stories that continue to other pages, such as a line that says “Continued on page 42.” Use a jump line page number to automatically update the number of the page containing a story’s next or previous threaded text frame when you move or reflow the story’s threaded text frames.
Usually the jump line page number should be in a separate text frame from the story it tracks. That way, the jump line page number remains in position even if the story’s text reflows.
