You can switch the visible area of an unfolded section from full to half, partial, broken, and vice versa. However, some attributes of the visible area may be lost during the switching due to missing references.

If a reference of the original visible area is missing, you are prompted to select a new reference.

If the reference related to a break line is missing, the break is removed and a message informs you about the deletion of the break that has a missing reference.

Annotations that have lost their references during the switching are erased. Additionally, annotations that are not valid for the switched visible area are erased. In both cases, a message informs you about the erased annotations. The switching of visible areas does not affect the orientation of annotations.
