The issue requests adding a search function to the help menu triggered by '/' key. Investigate the current help menu implementation in the codebase, likely in files like 'src/handle event.rs' or 'src/ui.rs'. See how other similar search features are implemented in the project (e.g., search in the main track list). Consider using a modal overlay or modifying the existing help view. Check linked PRs or comments for any prior attempts. The solution should allow filtering help commands by typing.
