Worked on the Excalidraw repository to enhance the reliability of keyboard shortcut behaviors, focusing on user interface stability rather than new feature development. Addressed a critical bug affecting the crowfoot arrowhead keyboard shortcuts by correcting the keybindings for crowfoot_one and crowfoot_many, ensuring that users could select arrowhead styles predictably through keyboard input. Utilized JavaScript and TypeScript to implement and validate these changes, emphasizing front end and UI development best practices. The work improved keyboard accessibility and reduced user errors, with thorough testing to maintain consistency across workflows. Prioritized maintenance and user experience improvements during this period of development.
