### Returns

| Type                                                                                      | Description |
| ----------------------------------------------------------------------------------------- | ----------- |
| [TouchScreenKeyboard](/engine/6000.5/script-reference/unityengine/touchscreenkeyboard.md) |             |

### Remarks

The `autocorrection` determines whether the input tracks unknown words and suggests a more suitable replacement candidate to the user, replacing the typed text automatically unless the user explicitly overrides the action. The `multiline` determines if user can input more than one line of text. The `secure` identifies whether the keyboard is used for password. Text in the input field will be hidden from the user except the recently typed character. The keyboard can be opened in the `alert` mode too. The `placeholder` string will be displayed when there is no other text in the input field of the keyboard.
