Use the Back key, repeatedly, to reach the highwater (last page read) marker 'setting page' (the page where you can set it to something else, one page forward, or backward, from the currently-displayed page of the e-book).

[EDIT: The title I gave to this post is slightly inaccurate, and I can't seem to change it.]

If you press it [the BACK key] one too many times, you will exit the book entirely. The next time you load the book, you will be at the highwater mark setting page.

From this page, you can change the highwater (last page read) marker, by pressing either Page Up, or Page Down.

That is the *only* way to change the highwater mark setting.

When you visit the highwater mark setting page for any ebook on Kindle, you are allowed to read the page itself. It will not look any different. You set the highwater marker from this page, and as a side-effect of setting the marker to a new location (one page behind, or forward, of the current page) .. you also get to view (read) the newly-exposed page.

Any *other* navigation can produce images of various pages, but you forever leave the highwater marker setting page (as I'm calling it) until you use the Back key, to retrace your steps, backwards (and thereby destroy the records of where you have visited -- Back is a one-way trip here).

It's frustrating to figure all this out, but near as I can tell, I have it correct: the Back key is the final arbiter of if you are to revisit the highwater marker setting page or not.

If you don't use this mental model, then it becomes a lot more trouble to explain why using PageUp or PageDown does not *always* change, also, the last page read marker (or highwater marker, as I prefer to call it).

Corrections welcomed. I do things a certain way, so I have not stumbled upon an exception to the way it seems to operate, the way I use Kindle, daily.

Hope this was of some help.
