Identifies the event raised whenever the text selection is modified.
Assembly: UIAutomationTypes (in UIAutomationTypes.dll)
Some text controls handle the text insertion point (cursor) as a zero-width text selection and might raise TextSelectionChangedEvent when the cursor is moved.
To follow cursor movements, UI Automation clients are advised to keep track of insertion point changes by listening for corresponding UI Automation element events rather than depending on TextSelectionChangedEvent.
This identifier is used by UI Automation providers. Client applications should use the equivalent field in TextPattern.
