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 portions,
or segments 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.
