.section Resizing the Zoom Window
.*

until the window is the desired size.
.step Release the mouse button.

Normally, Zoom only refreshes the selected area in the Zoom window
when the magnifier moves. When the Auto Refresh option Configuring Zoom: is selected,
Zoom refreshes the image displayed in the Zoom window at regular
intervals, as well as when the magnifier moves. This feature is useful
when magnifying screen images that change frequently, such as the
seconds on the clock application Configuring Zoom:.

When the enable auto refresh box in the configuration Configuring Zoom: dialog is
checked you can enter a value in the Interval field. This value
specifies the interval in tenths of seconds that Zoom will wait
between image refreshes.
