When you select or deselect objects in an InDesign document, InDesign generates the afterSelectionChanged event. When you change an attribute (the formatting or position) of the selected object or objects, InDesign generates the afterSelectionAttributeChanged event. These two events are useful when you want to create a script that responds to user actions.

Sample Selection Event Listeners
InDesign can respond to events related to selection. When you select or deselect objects in an InDesign
document, InDesign generates the
afterSelectionChanged
event. When you change an attribute (the
formatting or position) of the selected object or objects, InDesign generates the
afterSelectionAttributeChanged
event. These two events are useful when you want to create a script
that responds to user actions.
