Descriptions
The four
programmable
function (PF) keys directly above the keypad allows
navigation though the system mode menus and selection of specific terminal
operations.
Cancel Key
Pressing the cancel key in normal mode—when the terminal’s application is
loaded and running—usually has the same effect as pressing the Esc (escape)
key on a PC. That is, it terminates the current function or operation.
In system mode, use cancel to perform a variety of functions. The most common
use of cancel in system mode is to exit a system mode submenu and return to the
main system mode menu. The specific effect of pressing the cancel key depends
on the currently active system mode menu.
Backspace Key
In normal mode, the backspace key is commonly used to delete a number, letter,
or symbol on the terminal’s display screen. Press backspace one time to delete
the last character typed on a line. To delete additional characters, moving from
right to left, press backspace once for each character or hold down backspace to
delete all characters on a line.
In system mode, the specific effect of pressing backspace depends the currently
active system mode menu.
ALPHA Key
In normal mode, the ALPHA key enables you to enter one of the two or more
characters or symbols assigned to individual keys on the 12-key Telco-style
keypad. Use the ALPHA to enter up to 50 different ASCII characters through the
following procedure:
1 Press the key on the 12-key keypad that shows the letter or symbol you want
(for example, use 2 to type 2, A, B, or C). The number (1–9 or 0) or the symbol
(* or #) you pressed now displays.
2 Press ALPHA once to display the first letter. Continuing our example, 2
ALPHA displays the letter A.
