The Operations → Duplicate function or the button allows you to make a copy of any image, curve or section opened in the program.
To make copy of a window select it and then click the button. If you want to copy a part of the image select this part with standard selection tool and then make a copy. Only the selected area will be copied. The selection with complex shape will be copied as a rectangle circumscribed about the selection.
Part of a curve or section can be selected for copying the same way by vertical marks.
Special functionality is provided for operations with force maps.
