# NSTextSelectionManager

An object that coordinates text selection behavior for custom text views.

## Declaration

```swift
@MainActor class NSTextSelectionManager
```

## Overview

Overview NSTextSelectionManager provides a centralized way to manage text selection interactions using a set of gesture recognizers. For keyboard-based selection, integrate NSTextSelectionNavigation with your view. The selection manager works with a delegate to update and respond to selection changes, and with a data source to query the text layout system.
