## Discussion

[`NSEvent.EventType.smartMagnify`](/documentation/AppKit/NSEvent/EventType/smartMagnify) represents the smart zoom gesture (that is, a two-finger double tap on trackpads), along with a corresponding [`NSResponder`](/documentation/AppKit/NSResponder) method. In response to this event, you should magnify the content appropriately for your app. For example, you might zoom in on a specific paragraph or image.
