If you are reading a Kindle book, the menu will contain the following selections:
Home — takes you to your Home screen.
Shop in Kindle Store — takes you to the Kindle Storefront.
Go to Cover — takes you to the cover page of the item you are reading. This is usually the cover of the book if it has one.
Table of Contents — takes you to the Table of Contents for the item you are reading.
Go to Beginning — takes you to the place in the book the publisher considers to be the beginning. This is usually the first chapter, but may be a foreword, the table of contents, or other point the publisher chooses.
Go to Location… — displays a text entry box that allows you to jump to a specific location in the content.
Sync to Furthest Page Read — connects to Amazon.com and compares your current reading location with the one saved at Amazon. If you are further along in your book using another device, Kindle gives you the choice to go to the furthest page read.
Go to Bookmark… — displays a list of bookmarks you have made in the item you are reading and allows you to jump to any one of them.
