There are times when you have two or more objects that always belong together, as in the case of shadow boxes, the text and the box will always remain together. I such cases, you can Group the objects under question. Then when you move any one of the objects in the group, all will move together, and their relative position will remain constant.
To create a group, follow the following process:
1) Select all the objects that are to be in the group.
2) Choose Element followed by Group or Press (Ctrl + G).
Now to select a group, you need to click any of the objects comprising the group. In case you want to modify one of the objects in the group, you can do so without breaking the group. Hold down the Ctrl key as you click the object you want to modify (with the pointer tool selected). You can then change its attributes, reposition it, resize it, etc. If text is part of the group, you can directly edit it using the text tool as is normally done. However, if you need to ungroup a group, choose:
1) Select the grouped objects.
2) Element à Ungroup or press (Shift + Ctrl + G).
