Group and Lock Annotations
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.
Grouping and Ungrouping Annotations
To group a number of annotations, select the annotations, and choose Edit 
Selection Group. Use Edit Selection Ungroup to ungroup them again.
Locking and Unlocking Annotations
To lock one or more annotations, select the annotations, and choose Edit Selection Lock. Use Edit Selection Unlock to unlock them again.
 | If a selection contains locked annotations as well as unlocked annotations, only the unlocked annotations will be selected. Locked annotations can still be selected (and unlocked) separately, or by locating them in the Annotations Sidebar. |
