Docnav

A Cmd+K command palette and sticky outline for any documentation site.

docnav makes every documentation site keyboard-driven. ▎ ▎ Press Cmd+Shift+K (or Ctrl+Shift+K on Windows/Linux) to open a fuzzy command palette over every h1–h4 on the page. Type a few letters, hit ▎ Enter, scroll-snap to the heading. Press Cmd+Shift+O to toggle a sticky outline panel that highlights the section you're reading as you ▎ scroll. ▎ ▎ The palette also surfaces docs pages you've recently visited, so jumping back to a page you read yesterday doesn't require remembering the URL ▎ — and if that page is already open in another tab, docnav switches to that tab instead of opening a duplicate. ▎ ▎ Features: ▎ – Cmd+K fuzzy palette over headings (h1 to h4) ▎ – Sticky outline panel with active-section highlighting ▎ – Recent docs surfaced in the palette and popup ▎ – Switches to an existing tab when you re-open a Recent page (instead of duplicating) ▎ – Per-site enable/disable toggle from the popup ▎ – Light / Dark / System theme ▎ – Rebindable global hotkeys via chrome://extensions/shortcuts ▎ – UI rendered inside a shadow DOM, so it can't be styled by — or interfere with — the host page ▎ ▎ Works on MDN, React, Next, Tailwind, TanStack, Docusaurus-style sites, and anything else with <h1>–<h4> markup. All data stays on your ▎ machine.
