First, I need to disclose that I am proficient with Kindles and a noob with Nooks.

Kindles have the "back" button that lets you backtrack after following hyperlinks to the initial position. I've noticed that after following a hyperlink for an endnote or footnote on my Nook C, there appears a "Back" button at the top; however, it disappears after a couple of seconds and I am stuck at the footnote and have no way (that I can see) to return to where I was. How do I bring back that "Back" button? What am I missing?

Another variation. If I follow the link and make several page turns, can I retrace to the place before I followed the hypelink?

Also after I follow several hypelinks in a row, is there a way to backtrack all the way to my initial position (many steps back, not one)?

While my questions are about Nook Color, I would also like to know about the regular Nook. Does it allow going back after following hyperlinks?

P.S. Yes, I searched before posting.
