Objects can be
grouped so that they always are selected and moved together. The
objects can also be ungrouped or regrouped (after ungrouping). Members
of the same group can also share a set of group-specific properties.
Multiple groups and objects can be combined to form a single group.
Procedure
- Select more than one object.
- Choose the Draw > Group > Group menu
item.

Regroup icons on the Layout Bar:
