An Open Letter to Amazon Com

I bought a Kindle Model D00701.  I bought a book titled "The Complete User's Guide To the Amazing Amazon Kindle" by Stephen Windwalker.  Pages 25-27 describe "Kindle Keyboard and Menu Shortcuts" mostly involving the ALT key.  Most of those don't work on my Kindle.  I wondered whether the problem was with my unit, my operation of the unit, or the book.  I asked support in an e-mail but their response was the suggestion for phone support.  The person I talked to had an accent and didn't seem to understand the question.  When he finally tried to transfer me the connection was lost.  Why couldn't they just e-mail me the answer?  I sent another request but got the same response.
