I need to reference content on another page, but I don't want to have to update the page number manually if things shift. For instance, I've got an activity in a checklist and I'd like to include, "For details, see page XX", and the supporting content is detailed there. But I know there will be content that needs to be inserted that will shift pages. I'm not sure where to start looking to figure out how to set this up. Your assistance is appreciated!
What you want is a Cross-Reference. They were introduced in CS4, and you'll find them in the Hyperlinks panel.
