Hi,
LC Designer has a library object for page navigation:
![Parallels Desktop1.png Parallels Desktop1.png](/t5/image/serverpage/image-id/828i4D163DED43DC9D05/image-size/large?v=v2&px=999)
It is a good place to start scripting buttons to jump to different pages, especially if the number of pages in the form is fixed.
An example is here: https://acrobat.com/#d=GRnm2-sKDGncwg*s0J1psg
If you go down this route you can put a button with no fill, line or caption over the 'Chapter 2' text. Or you can give the button a 'Chapter 2' caption.
With a bit more script you can create an index button, where the choices come up an an alternative menu.
Examples here:

Hope that helps,
