# isMouseCoalescingEnabled

A Boolean value that indicates whether the system coalesces mouse movement events.

```
class var isMouseCoalescingEnabled: Bool { get set }
```

## Discussion

Mouse movement events include mouse-moved, mouse-dragged, and tablet events. If this property is <doc://com.apple.documentation/documentation/Swift/true>, coalescing is enabled; otherwise, it’s disabled. The default value of this property is <doc://com.apple.documentation/documentation/Swift/true>.
