Developed enhancements for the zed-industries/gemini-cli project, focusing on improving terminal input handling and Markdown editing workflows. Introduced support for Alt+key combinations, enabling users to input accented characters and navigate more efficiently across various terminal environments. Implemented a keyboard shortcut to toggle between rendered and raw Markdown views, streamlining content creation and review directly within the CLI. The work leveraged JavaScript, TypeScript, and React, emphasizing robust front end development and thorough testing practices. These features addressed cross-terminal compatibility and accessibility, resulting in a more efficient and user-friendly command-line experience for Markdown editing and navigation tasks.
