Making selections is
critical to be able to use Illustrator effectively. In order to make
any kind of adjustment to a drawing you must first select what you
wish to manipulate.
Illustrator takes advantage of the following
selection tools:
The selection tool is used to select entire objects
The Direct Selection Tool is used to select pieces
or control points of objects
The Group selection tool is used to select a single object
within a set of objects you have defined as a group.
Position
the selection tool over the portion of the artwork that you wish to
manipulate and click. When the object turns blue you know that it
has been selected.
