How can I implement keyboard navigation for accessibility in Angular?

To implement keyboard navigation in Angular, you can use the Angular CDK's a11y package, which provides utilities for managing focus and keyboard events.

Can you give me an example of how to use the CDK for this?

Sure! You can use the FocusKeyManager to manage focus on a list of items. Here's a simple example:

import { FocusKeyManager } from '@angular/cdk/a11y';

export class MyComponent {
  keyManager = new FocusKeyManager(this.items);

  handleKeydown(event: KeyboardEvent) {
    this.keyManager.onKeydown(event);
  }
}

What about handling focus when navigating with arrow keys?

You can extend the FocusKeyManager to handle arrow key navigation by listening for the arrow key events and updating the focus accordingly. Make sure to call keyManager.setFirstItemActive() to set the initial focus.
