## Overview

The [`BETextInput`](/documentation/BrowserEngineKit/BETextInput) protocol’s [`requestDocumentContext(_:completionHandler:)`](/documentation/BrowserEngineKit/BETextInput/requestDocumentContext(_:completionHandler:)) and [`requestTextContextForAutocorrection(completionHandler:)`](/documentation/BrowserEngineKit/BETextInput/requestTextContextForAutocorrection(completionHandler:)) methods provide an instance of this class to their completion handlers.

## Topics

### Creating a text document context

[`init(attributedSelectedText:contextBefore:contextAfter:markedText:selectedRangeInMarkedText:)`](/documentation/BrowserEngineKit/BETextDocumentContext/init(attributedSelectedText:contextBefore:contextAfter:markedText:selectedRangeInMarkedText:))

Initializes a document with attributed strings that represent the selection and its surrounding context.

[`init(selectedText:contextBefore:contextAfter:markedText:selectedRangeInMarkedText:)`](/documentation/BrowserEngineKit/BETextDocumentContext/init(selectedText:contextBefore:contextAfter:markedText:selectedRangeInMarkedText:))

Initializes a document with plain text strings that represent the selection and its surrounding context.

### Accessing autocorrected ranges

[`autocorrectedRanges`](/documentation/BrowserEngineKit/BETextDocumentContext/autocorrectedRanges)

An array of ranges that identify text the system autocorrects, relative to the context string.
