This chapter introduces some of the terms you'll need to know and then takes you on a tour of MH-E1. When you're done, you'll be able to send, read, and file mail, which is all that a lot of people ever do. But if you're the curious or adventurous type, read the rest of the manual to be able to use all the features of MH-E. I suggest you read this chapter first to get the big picture, and then you can read the manual as you wish.
 The keys mentioned in these chapters refer to the default key bindings. If you've changed the bindings, refer to the command summaries at the beginning of each chapter for a mapping between default key bindings and function names.
