# NSAccessibilityCustomRotor

A context-sensitive function that helps VoiceOver users find the next instance of a related accessibility element.

```
class NSAccessibilityCustomRotor
```

## Overview

Assistive apps, like VoiceOver, provide interfaces to quickly search apps for content of a specific type. For example, in a web browser, a user can quickly explore a list of navigational links or buttons using VoiceOver’s content menus.

[`NSAccessibilityCustomRotor`](/documentation/AppKit/NSAccessibilityCustomRotor) provides a way for apps to vend their own content menus. For example, Pages can create a *Headings* custom rotor that allows assistive apps to search the Pages document for all headings.

## Topics

[`init(label:itemSearchDelegate:)`](/documentation/AppKit/NSAccessibilityCustomRotor/init(label:itemSearchDelegate:))

Creates a custom rotor with the specified label and item search delegate.

[`init(rotorType:itemSearchDelegate:)`](/documentation/AppKit/NSAccessibilityCustomRotor/init(rotorType:itemSearchDelegate:))

[`NSAccessibilityCustomRotorItemSearchDelegate`](/documentation/AppKit/NSAccessibilityCustomRotorItemSearchDelegate)

The delegate for loading item results that don’t have a backing UI element at loading time.

[`NSAccessibilityElementLoading`](/documentation/AppKit/NSAccessibilityElementLoading)
