Soft Keys
Soft Keys
The four keys below the screen are called soft keys because their functions
change according to the operation. The soft keys are grouped into related sets
and subsets providing access to the various functions. The soft key labels are
displayed on the screen just above the keys. The default soft keys are displayed
until you press a key, or select an item on the screen; the soft keys associated
with the action are then displayed.
The currently selected soft key option is shown by its green background. If the
key text is displayed in gray rather than in black, it is not currently available.
When you press a soft key one of the following happens:
i. The associated operation is actioned, e.g.
NORTH UP
.
ii. A sub-set of soft keys is displayed, providing further functions.
iii. A pop-up menu is displayed, providing further options.
As with dedicated keys, when you press a soft key a single audio beep
confirms the key action. If the key-press is not valid for the current screen or
mode, three rapid beeps sound to indicate that no response is available. If
required, you can turn the key beeps off as part of your set up procedure (see
Chapter 7).
Pop-Up Menus
Pop-up menus usually provide set up options. When a pop-up menu is on-
screen, a set of associated soft keys is also displayed as shown in Figure 1-5.
