Summary of Changes

Hello @gemini-cli-robot, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refines the handling of Alt (Meta) key combinations for macOS users within the CLI. It specifically targets and remaps certain Alt key outputs (like "∫" for Alt+b) to their intended base characters, ensuring consistent functionality for actions such as moving words or toggling markup views. The change includes updated documentation and dedicated tests to confirm the correct behavior across various macOS terminal environments.

Highlights

• Refined macOS Alt Key Handling: The CLI's keypress context now specifically remaps Alt+b, Alt+f, and Alt+m (which produce "∫", "ƒ", "µ" on macOS) to their base characters, ensuring consistent functionality for actions like moving words or toggling views.
• Platform-Specific Remapping: The Alt key remapping logic has been updated to explicitly apply only when the application is running on macOS (process.platform === 'darwin'), preventing unintended behavior on other operating systems.
• Updated Documentation: The keyboard-shortcuts.md file has been updated to include a new section detailing these specific Meta+key combinations and their functionality on Mac, improving user understanding.
• Enhanced Testing: New tests have been added to verify the cross-terminal Alt key handling specifically for macOS, ensuring correct behavior for Alt+b, Alt+f, and Alt+m across different terminal emulators like iTerm2, Ghostty, MacTerminal, and VSCodeTerminal.

Code Review

This pull request cherry-picks a fix for handling Meta+key combinations on macOS. The changes correctly limit the special character remapping logic to the 'darwin' platform and scope it to only the necessary key mappings (b, f, m). The accompanying test changes properly mock the platform to ensure the new logic is covered, and the documentation is updated to reflect this Mac-specific behavior. The changes are well-implemented and improve the robustness of keyboard input handling. I have no further suggestions.
