Selection class
Availability
Flash Player 5.
Description
The Selection class lets you set and control the text field in which the insertion point is located
(that is, the field that has focus). Selection-span indexes are zero-based (for example, the first
position is 0, the second position is 1, and so on).
There is no constructor function for the Selection class, because there can be only one currently
focused field at a time.
