# automaticRearrangementKeyPaths

An array of key paths that trigger automatic content sorting or filtering

```
var automaticRearrangementKeyPaths: [String]? { get }
```

## Discussion

Subclasses can override this property to customize the default behavior of the sort descriptors and filtering predicates, for example, if additional arrangement criteria are used in a custom implementation of [`arrangedObjects`](/documentation/AppKit/NSArrayController/arrangedObjects).
