I figured out that using the arrow keys is the way.

I am new to Screenshot Captor.
I have an application that provides maps.  In order to capture an entire target region I would need to scroll down.  (The addition section I want to include lies below what is currently in the window.)

The application does not have a scroll feature.  (The mouse wheel controls a zoom feature.)  In order to see parts of the map that are not in the current window I need to "pan". (move the screen content around with the mouse)

I would appreciate some guidance on this. Is there a tutorial that addresses this specific situation?
