Worked on the helix-editor/helix repository to enhance keyboard-driven navigation within completion menus, focusing on improving developer productivity and accessibility. Developed and integrated PageUp and PageDown key handling for completion menus and related popups, allowing users to efficiently navigate long lists of options. The implementation involved careful event handling and UI development using Rust, ensuring changes were incremental and safely integrated with existing editor internals. No major bugs were addressed during this period, as the work concentrated on targeted user experience improvements. All changes were validated through established test suites and Git workflows, demonstrating attention to code quality and review processes.
