How can I implement keyboard navigation in my Angular app?

You can implement keyboard navigation in Angular by using the HostListener decorator to listen for key events.

Can you show me a code example?

Sure! Here's a simple example:

import { Component, HostListener } from '@angular/core';

@Component({
  selector: 'app-keyboard-navigation',
  templateUrl: './keyboard-navigation.component.html'
})
export class KeyboardNavigationComponent {
  @HostListener('document:keydown', ['$event'])
  handleKeyboardEvent(event: KeyboardEvent) {
    if (event.key === 'ArrowUp') {
      // Move focus up
    } else if (event.key === 'ArrowDown') {
      // Move focus down
    }
  }
}

What if I want to navigate through a list of items?

You can maintain an index of the currently focused item and update it based on the key events. Use ngFor to render the list and apply focus accordingly.
