Keyboard provides an api for managing a virtual keyboard. The high level api is [Keyboard.type()](./puppeteer.keyboard.type.md), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page.
For finer control, you can use [Keyboard.down()](./puppeteer.keyboard.down.md), [Keyboard.up()](./puppeteer.keyboard.up.md), and [Keyboard.sendCharacter()](./puppeteer.keyboard.sendcharacter.md) to manually fire events as if they were generated from a real keyboard.
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Keyboard` class.
## Example 1
An example of holding down `Shift` in order to select and delete some text:
If `key` is a single character and no modifier keys besides `Shift` are being held down, a `keypress`/`input` event will also generated. The `text` option can be specified to force an input event to be generated. If `key` is a modifier key, `Shift`, `Meta`, `Control`, or `Alt`, subsequent key presses will be sent with that modifier active. To release the modifier key, use [Keyboard.up()](./puppeteer.keyboard.up.md).
After the key is pressed once, subsequent calls to [Keyboard.down()](./puppeteer.keyboard.down.md) will have [repeat](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/repeat) set to true. To release the key, use [Keyboard.up()](./puppeteer.keyboard.up.md).
Modifier keys DO influence [Keyboard.down()](./puppeteer.keyboard.down.md). Holding down `Shift` will type the text in upper case.
If `key` is a single character and no modifier keys besides `Shift` are being held down, a `keypress`/`input` event will also generated. The `text` option can be specified to force an input event to be generated.
Modifier keys DO effect [Keyboard.press()](./puppeteer.keyboard.press.md). Holding down `Shift` will type the text in upper case.
Modifier keys DO NOT effect [Keyboard.sendCharacter](./puppeteer.keyboard.sendcharacter.md). Holding down `Shift` will not type the text in upper case.
