Creating a Group
Combines all selected objects into a group. This tool is available on the Groups and Blocks toolbar, or on the icon in the Drawing Tools.
...
Note: The new group will be placed on Layer 0 if its components are originally on different layers. See Snap Modes. If you explode a group, the objects will return to their original layers. Layer 0 should always be left visible, or newly created groups will instantly "disappear."
...
If you open the Selection Info Palette, you can view the contents and properties of a selected group.
You can highlight any component of the group to view its individual properties as well.
