Main Menu Key Cursor
With the exception of the SYSTEM key, when any
main menu key is pressed, the main menu that is
displayed contains a cursor positioned adjacent to
the pressed key (Figure 3-2). The cursor is displayed
on all sub-menus of the current menu until a differ-
ent main menu key is pressed.
When the SYSTEM key is pressed, the System
menu is displayed. The System menu and its sub-
menus do not contain a main menu key cursor.
Menu Soft-Keys
As shown on the left, five menu soft-keys are located
below the data display and five menu soft-keys are
located to the right of the data display. In general,
the menu soft-keys located below the data display
select a sub-menu of the current main (top-level)
menu display; the menu soft-keys located to the
right of the data display either control a function on
the current menu display or select an additional
sub-menu. Menu labels that identify the current
function of each soft-key are shown on the menu dis
-
play adjacent to the soft-keys.
