Chapter 1: Overview
Trackpad and Cursor
The trackpad is used to move the cursor horizontally, vertically or
diagonally. The cursor is the cross-hair symbol (+) which is used to select
a position or item on the chart.
The longer that the edge of the trackpad is pressed, the faster the cursor
moves. The current cursor position is shown in the status bar at the top of
the screen.
The cursor is context-sensitive. Some items on the screen, such as
waypoints and chart objects have information associated with them.
When the cursor is placed over such objects, their information is
displayed in the status bar. In addition, a function bar is displayed for
certain items. For example, when the cursor is placed over a waypoint,
the waypoint data is displayed in the status bar and the waypoint options
function is displayed.
Note: During many operations the cursor cannot be moved around the
screen, eg. whilst a function bar is displayed, the cursor is used exclusive-
ly for selection. In such cases, three rapid beeps indicate invalid action.

2. A pop-up menu is displayed, providing further options.
3. A set of functions is displayed.
As a key is pressed, 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, the key beeps
can be turned off as part of your set up procedure (see Chapter 4).
Press: Press the key momentarily and then release it. This method is
used for most key operations.
