There's no reason why you shouldn't use links elsewhere as well, but you'll need to do a lot of testing.
Many thanks! Do you know where I can read and learn on how to insert links in the Kindle book like we are talking about? I managed to find a guide on how to do the ToC but not on how to link inside the book.
