4.2.1 Pointing Devices – Trackball and Mouse
All user interface controls are operated by the mouse or trackball which is connected to the respective
MFD. Even if you are already familiar with using input devices like mouse or trackball, you will find one
or the other important note in this section.
Fig. I / 6 Possible pointing devices
To start an operating step move the pointer on the screen by moving the trackball or mouse. Move the
pointer to the desired position on the screen, e.g. to a text item, a numerical value, a symbol, or any
desired position e.g. on the PPI. The shape of the pointer changes when you point at different elements
on screen. The pointer’s shape depends on the application and the element you point at. See chapter I
- 5.10 on page 82.
When you point at a click-sensitive (clickable) element on screen then you can press and release (click)
one of the trackball keys to display information or activate a function. The possible types of clicks are
explained separately. See chapter I - on page 31. The specific effect of clicking depends on the key
used, the element you clicked, and the operating situation. This is described in the specific parts of these
operating instructions. Desktop trackball or mouse have two different buttons, DO and MORE key. The
functions of the DO and MORE keys are described in the following.
DO Key
The most frequently used of the keys is the DO key, i.e. the middle key on the built-in trackball and the
left button of the desktop trackball and mouse. Most elements on screen respond to this key by opening
a menu from which you can select frequently used functions.
In these operating instructions, "clicking" always means pressing the DO key. When you have to
press the MORE key or the right mouse/trackball button, this will be explicitly explained in the
instructions.
