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 only be one currently focused field at a time.
