From the Kindle WordPress blog:
Jump to beginning or end of Kindle Home menu or a Kindle Book
For Home Menu:
1.
On your Home menu, if you hold down the Next Page button for about a second before releasing it, the Kindle will jump to the end of the list. Similarly, holding the Previous Page button will jump to the beginning.
For a Book:
1. While in the eBook, roll your select roller up from the “menu” one notch (so it is over the progress bar) and click it. You will get a ruler showing all of the bookmarks (as tabs) and a representation of the number (1, 2, … 0) keys. If you have set no, or few, bookmarks, simply press the “next page” bar and you will zoom to the end.
1. If you have set bookmarks, press the “0″ key to move close to the end, and then press the “next page” bar. The numeral keys will move you to relative positions in the text.
2. Alternatively, you can always go into the “menu” and select “Go to Location.” By putting in a location number greater than the maximum that shows (e.g., something like “9999″), you will go directly to the end.
