title: Playwright on Mac does not support all keyboard shortcuts
body: <p>On a macOS, some of the shortcuts are available with playwright, such as: Meta+A, Meta+V.</p>
  <p>However, undo and redo methods which are committed by Meta+Z and Meta+Y do not work.</p>
  <pre><code>     await this.page.keyboard.down('Meta');
       await this.page.keyboard.press('Z');

  </code></pre>
