Ealona Shmoel enhanced the accessibility of the Definition Widget in the Khan/perseus repository by implementing improved keyboard navigation and interaction. Using React with JavaScript and TypeScript, Ealona enabled users to dismiss the widget’s popover with the Escape key and navigate between interactive elements using Tab and Shift+Tab. This targeted update addressed usability for keyboard-only users and those relying on assistive technology, aligning with broader accessibility initiatives. The work established a reusable pattern for keyboard navigation within widgets, providing a foundation for future accessibility improvements across the codebase and demonstrating thoughtful attention to user experience and maintainable front end development practices.
