Annotations can be arranged in groups and locked to prevent editing. In a group of annotations, only all annotations at once can be selected, moved and modified. Once you select one annotation of a group, all of them will be selected. Locked annotations cannot be moved or modified until you unlock them.
To group a number of annotations, select the annotations, and choose Edit Selection Group. Use Edit Selection Ungroup to ungroup them again.
To lock one or more annotations, select the annotations, and choose Edit Selection Lock. Use Edit Selection Unlock to unlock them again.
