7.4 The keyboard

7.4.1 Introduction

The keyboard is used for typing and to control the MP2500.
Typing is provided by letter keys organised in an alphabetical layout, with
separate numeric keypad and cursor key clusters. Symbols and punctuation
are provided by SHIFT (S) plus letter keys. This provides access to all the
functions that you are likely to need, although applications can also redefine
any of the keys to provide access to other functions, if required.
