Keyboard

Keyboard class

Keyboard provides an api for managing a virtual keyboard. The high level api is Keyboard.type(), which takes raw characters and generates proper keydown, keypress/input, and keyup events on your page.

Signature:

export declare class Keyboard

Remarks

For finer control, you can use Keyboard.down(), Keyboard.up(), and Keyboard.sendCharacter() 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.

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:

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

await page.keyboard.down('Shift');
await page.keyboard.press('KeyA');
await page.keyboard.up('Shift');
