# Keyboard class
|
|
|
|
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.
|
|
|
|
#### Signature:
|
|
|
|
```typescript
|
|
export declare class Keyboard
|
|
```
|
|
|
|
## Remarks
|
|
|
|
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.
|
|
|
|
On macOS, keyboard shortcuts like `⌘ A` -> Select All do not work. See [\#1313](https://github.com/puppeteer/puppeteer/issues/1313).
|
|
|
|
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:
|
|
|
|
```ts
|
|
await page.keyboard.type('Hello World!');
|
|
await page.keyboard.press('ArrowLeft');
|
|
|
|
await page.keyboard.down('Shift');
|
|
for (let i = 0; i < ' World'.length; i++)
|
|
await page.keyboard.press('ArrowLeft');
|
|
await page.keyboard.up('Shift');
|
|
|
|
await page.keyboard.press('Backspace');
|
|
// Result text will end up saying 'Hello!'
|
|
```
|
|
|
|
## Example 2
|
|
|
|
An example of pressing `A`
|
|
|
|
```ts
|
|
await page.keyboard.down('Shift');
|
|
await page.keyboard.press('KeyA');
|
|
await page.keyboard.up('Shift');
|
|
```
