# AccessibilityScrollDirection

> Describes the direction of a scrolling action.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEngine.Accessibility](/engine/6000.7/script-reference/unityengine/accessibility.md)
* **Assembly:** UnityEngine.AccessibilityModule

```csharp
public enum AccessibilityScrollDirection : byte
```

## Remarks

The values in this enumeration are used by the [\_scrolled](/engine/6000.7/script-reference/unityengine/accessibility/accessibilitynode/scrolled.md) event, which is sent when a screen reader user performs a scrolling action.

Each direction describes how the visible region of the content should move: [AccessibilityScrollDirection.Up](/engine/6000.7/script-reference/unityengine/accessibility/accessibilityscrolldirection/up.md) and [AccessibilityScrollDirection.Left](/engine/6000.7/script-reference/unityengine/accessibility/accessibilityscrolldirection/left.md) should move the visible region toward the start of the content, revealing the content above or to the left of it, and [AccessibilityScrollDirection.Down](/engine/6000.7/script-reference/unityengine/accessibility/accessibilityscrolldirection/down.md) and [AccessibilityScrollDirection.Right](/engine/6000.7/script-reference/unityengine/accessibility/accessibilityscrolldirection/right.md) should move it toward the end. [AccessibilityScrollDirection.Forward](/engine/6000.7/script-reference/unityengine/accessibility/accessibilityscrolldirection/forward.md) and [AccessibilityScrollDirection.Backward](/engine/6000.7/script-reference/unityengine/accessibility/accessibilityscrolldirection/backward.md) should scroll to the next and previous portion of the content along its main scrolling axis.
