I must admit, I thought about doing the very same thing but wasn't prompted to try my scheme until I saw your post.
1) Make a "key identifier" above your file reference e.g. "aa". This just serves as a marker
2. Make the text color white for your file reference. Magic Launch still works, even though neither you (nor the printer) will see the text.
3. Make sure there is a "normal" entry (black text) after your white entry because for some reason, the white color doesn't "take" unless it is turned off by a succeeding entry (David, Is this a bug?)
Now when you print, your references will not, and the aa or other "marker" alerts you to the presence of an entry below. Since all the markers can be the same, you can follow the links to the references.
If you want to see the all the references, use the command, Strip all colors, sorry Strip all colours
