Zooming and Scale

How do I Zoom to change the Map scale?

Zooming changes the Map scale and is accomplished in one of three ways:

1)      Command bar ‘ Zoom’ and select scale

2)      Menu > Zoom and select scale

3)      Display the Navbox ‘ Zoom+’ or ‘Zoom-’ and press either button on screen

Note: It is also possible to assign the Zoom action to any one of the Navboxes displayed on screen, see  Assigning Actions to Navboxes.
