What are the best practices for manual keyboard testing?

Familiarize yourself with accessibility guidelines and standards, such as WCAG, to ensure you have a thorough understanding of keyboard accessibility requirements.

1. Test with multiple web browsers: Different browsers may handle keyboard interactions differently, so it's important to test with popular browsers such as Chrome, Firefox, and Safari.
2. Test with different operating systems: Keyboard behavior can also vary across operating systems, so test with different platforms like Windows, macOS, and Linux.
3. Document and prioritize issues: Keep a detailed record of any keyboard accessibility issues you encounter during testing, including their severity and impact on usability. Prioritize fixing critical issues first.
