## Keyboard.down() method
Dispatches a `keydown` event.
<b>Signature:</b>
```typescript
down(key: KeyInput, options?: {
text?: string;
}): Promise<void>;
```
## Parameters
| Parameter | Type | Description |
| --- | --- | --- |
| key | [KeyInput](./puppeteer.keyinput.md) | Name of key to press, such as <code>ArrowLeft</code>. See [KeyInput](./puppeteer.keyinput.md) for a list of all key names. |
| options | { text?: string; } | An object of options. Accepts text which, if specified, generates an input event with this text. |
<b>Returns:</b>
Promise&lt;void&gt;
## Remarks
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.
