Show HN: HN Keyboard Boost – Minimal Keyboard Navigation for Hacker News
HN Keyboard Boost is a browser extension that adds minimal keyboard navigation to Hacker News. It is available for both Firefox and Chrome, with source code on GitHub. The developer created it as a fun side project to make browsing HN more keyboard-friendly.
Background
- Hacker News (HN) is a massively popular tech-news and discussion site run by Y Combinator (the startup accelerator). It is deliberately minimalist — no infinite scroll, no rich UI — and has no built-in keyboard navigation for browsing comment threads or links.
- "Show HN" is a convention on HN where users share a personal project they've built. This is a browser extension, not a site feature.
- The author says they "vibecoded" it — a term that is spreading in AI discourse to mean building software quickly by prompting an AI assistant (in this case "GPT 5.5", though note that OpenAI's public models top out at GPT-4o and o-series; "5.5" may be a joke, a typo, or a reference to an internal/preview model). The phrase signals that the code was largely generated by an LLM rather than written by hand.
- The extension adds basic j/k keybindings (like Gmail, Reddit, or Vim) to navigate HN items and comments, filling a long-standing gap for keyboard-centric power users who find the site's lack of shortcuts frustrating.
