If you have selected multiple objects in the graphics pane, you can choose Grouping|Group from the context menu of one of the objects or Graphics|Group|Group from the main menu to group the objects. When objects are grouped, they behave as a single object. Hence, when you select one object, all objects in the group are selected. When you edit the graphical property (e.g., font, background color) of one object, the corresponding property of all objects in the group is modified.
Note: Elements cannot be a member of a group. Only graphical objects, text, images and hyperlinks can be members of a group.
To Ungroup the set of objects, select the Group, and choose Grouping|Ungroup from the context menu of one of the objects or Graphics|Group|Ungroup from the main menu.
The Group and Ungroup options are also available in the Graphical Tools toolbar:
