Snap to Guide Lines snaps selected objects to nearest guide line when user moves objects in the Transformation mode. Objects are snapped only if they are near to the guide line. This function allows user to align objects with use of the guide lines. It works with whole objects (not just edited nodes as snap options under then main menu > Nodes).

Lock Guide Lines disables editing of guide lines and adding of new guide lines. Locking of guide lines prevents unwanted seizure of guide lines when working with digitized objects in the work area.

Erase Guide Lines deletes all guide lines in the work area.

Copy and Paste are clipboard operations.
