6 Introduction
Keyboards
The “PC” keyboards, including the EPC (101-key) and the PC/+
(106/107-key), are similar in style and feature a number of key
groups.
The alphanumeric keypad is the main typewriter keypad, while
the function key group lies along the top of the keyboard and can
be programmed locally or downloaded from the host. The
numeric keypad is the calculator-style set of keys on the right-
hand side of the keyboard, used to enter numeric data.
The cursor and edit keypads, located to the left of the numeric
keypad, allows users to edit text and move around in the
document. The communication key group, above the edit
keypad, is used to control communications with the host or
printer.
The ANSI keyboard varies from the PC keyboard styles mainly in
that it features 20 function keys, a set of PF-keys, and a different
style numeric keypad.
For each keyboard, there is a set of local “hot-keys.” They
perform a variety of terminal functions, such as “Print Screen”
and “Enter Setup.” (See Appendix A for a complete list of local
functions.)
