A group of annotations is comprised of one parent annotation and one or more child annotations. Any operation (delete, move, etc.) performed upon one annotation in a group will also be performed on the rest of group. Also, all children will display their parent's comments.
Create a group by selecting two or more annotations, right-clicking (Mac: Ctrl+click) on one of them, and choosing Group from the mouse context menu. The annotation that was right-clicked will be the parent.
Annotations may be ungrouped by right-clicking (Mac: Ctrl+click) on an annotation group and choosing Ungroup from the mouse context menu.
Note: that the following annotations cannot be included in a group: sound and text replace annotations.
