Zoom Out; Zoom Extents; Zoom Window - Garmin PC150 Owner's Manual

7.2 ZOOM OUT

This option enlarges the area of the map displayed on the screen, thus
reducing the appearance of the plot. The Zoom Out function enlarges the plot
display area to twice its original size (i.e., the distance from corner to corner
represents two times the original distance). The accelerator key for Zoom
Out is <Ctrl+O>.

7.3 ZOOM EXTENTS

This option resets the boundaries and scale of the map such that the plot
spans the entire display area. Note that new data points which are added to
the plot after it has been fitted to the screen may not be visible in the display
area.

7.4 ZOOM WINDOW

Zoom Window is an alternate way to zoom in on a specific area of your plot.
After selecting this option, the status line on the bottom of the screen will
indicate "Zoom Mode". The accelerator key for Zoom Window is <Ctrl+Z>.
Use the mouse to move the screen pointer near an area which you would like
to enlarge. Click the left mouse button once. A box outline will appear with
one corner attached to your screen pointer. Move the screen pointer using
your mouse until the box outline frames the area you wish to enlarge. Click
the left mouse button a second time and the area bounded by the box will be
scaled to fit your screen. To cancel the zoom window (without pressing the
left mouse button a second time), press Esc
< >.
