# Description
Handle the selectionChanged message if you want to perform updates or do some action when the user changes the selected text of a field or the selected portion of a player.
The selectionChanged message is sent to a field whenever the user makes a text selection or moves the insertion point in the field, after the selection is changed.
>*Note:* If the selection change is a result of the text being added or removed (for example, cut or paste over selected text), selectionChanged will not be sent, but rather textChanged.
The selectionChanged message is sent to a player whenever the user selects a portion of the sound or movie, or when a handler sets the player startTime or endTime property.
>*Note:* If an already-selected-item in a list is reselected a > selectionChanged message will still be sent.
