Group objects

To manipulate elements as a single object, group them. For example, after creating a drawing, you might group the elements of the drawing so that you can easily select and move the drawing as a whole.

When you select a group, the Property inspector displays the x and y coordinates of the group and its pixel dimensions.

You can edit groups without ungrouping them. You can also select an individual object in a group for editing without ungrouping the objects.

Group and ungroup objects

Select the objects to group. You can select shapes, other groups, symbols, text, and so on.

To group objects, select Modify > Group, or press Control+G (Windows) or Command+G (Macintosh).
To ungroup objects, select Modify > Ungroup, or press Control+Shift+G (Windows) or Command+Shift+G (Macintosh).

Edit a group or an object within a group

Select the group, and then select Edit > Edit Selected, or double-click the group with the Selection tool.
Everything on the page that is not part of the group is dimmed, indicating that elements outside the group are inaccessible.
Edit any element within the group.
Select Edit > Edit All, or double-click a blank spot on the Stage with the Selection tool.
Flash restores the group to its status as a single entity, and you can work with other elements on the Stage.
