I'm making a book for print, chapters are still incomplete or without order. In several instances I need a text that says something like "if you want to know more go to page X", where let's say X is in page 25. If I go back and add more pages, page X is now on page 35 and I'd like it to change automatically.
I can find special characters markers for current page, previous page and next page, but not for a random assigned page.
it would be a pain to manually edit every "go to" in the book whenever new pages are added
You can use also a separate text frame, which must overlap the text frame of the story, e.g. at the end, write "Follow on " and insert the marker for the next page. On the followed story go to the beginning and make also overlapping text frame and write "Continued from " and insert previous page marker.
These text frame stays still, even if the content of the story changes and the page number is always correct.
