Avoid Keyboard "traps" and Bypass Blocks
Content should be designed so that keyboard navigation does not cause a user to get "stuck" on a part of a website and a user should be able to navigate directly to the main content.
Why
Users who rely on keyboard navigation should be able to access to both navigate to and navigate away from any plugin on the web page. Also, users who rely on keyboard navigation should be ale to get to a main part of a webpage without having to make several keystrokes, which may prove painful.
Best Practices
- Make sure all navigation is controllable by either the "Tab" key or arrow keys
- Provide a "Skip to Content" Link
