Working with Text Field Selections
When
a user selects a portion of a dynamic
or user-input text field, the positions of the selected characters
are stored in a special built-in object called the
Selection object. Using the
Selection object, we can check which part of a
text field a user has selected or even select a part of a text field
programmatically. The Selection object can also
tell us which of a series of text fields is currently selected by the
user. Finally, we can use the Selection object
to give keyboard focus to a particular text field, prompting a user
to type in a suggested location.
To learn how to work with text field selections, see the
Selection object in Part III.
