2.4 Using the RayChart Controls

The RayChart controls are summarized in the illustration on the
following fold-out page. The remainder of this section considers the
trackpad and soft keys in more detail, and provides some simple
exercises for you to try.

The Trackpad

The trackpad is used to move the cursor on the chart and around the
on-screen menu displays. The cursor is the cross symbol ( ) that is
visible on the chart.
You can push on any of the four dots on the trackpad, or midway
between two dots, to move the cursor in that direction. If you press and
hold down the trackpad, the cursor moves faster.
Try using the trackpad now to move the cursor around the chart. You
can use short presses on the trackpad to move the cursor small
distances, or press and hold to move the cursor quickly.
As you move the cursor to the edge of the display, the display pans
across the chart so that the area you have moved to remains in view. If
you continue to scroll, the chart is redrawn on the screen at intervals.
If you move the cursor over an object for which there is information
available, an Object Data Box appears at the top of the screen (see
Chapter 3).
The trackpad is also used to edit information and move around menus,
as described in Chapter 6.

The Soft Keys

The four soft keys are called "soft" because they can have completely
different functions when you select different modes of operation. This is
why the keys do not have labels printed on them. Instead, the labels for
the current functions are displayed on the screen immediately above
the keys.
You can control whether or not the soft key labels are displayed all the
time, using the system set up as described in Chapter 6. If no labels are
displayed, press one of the soft keys to make them appear. The labels
disappear again if you do not press a key for 7 seconds.
