The navigator palette is used to give you the ability to
make quick view changes of your work.
The view changes are:
Magnification: you can change the magnification in
your navigator palette by either entering the value you want in the box
designed for that purpose or by clicking on the zoom in – zoom out buttons,
and you can also drag the slider designed for that purpose.
Moving the view: to move the view entered a high
magnification value, just drag the box you see inside the colored thumbnail
in your navigator palette, you’ll see that the original image is moving to
the exact position that you dragged the box to in your navigator palette.
If you click on the palette options button under
the close button in the navigator palette a pop up menu will appear giving
you he ability to change the color of thumbnail area by selecting a color
from the color picker dialog box.
