Keysmith — Custom Keyboard Shortcuts

Custom keyboard shortcuts that work on open tabs immediately.

Keysmith lets you bind any key combination to 50+ browser actions — and it works the moment you install it. WHY KEYSMITH • Works immediately: shortcuts run on tabs you already have open. No page reloads, no developer-mode switches, no "Allow user scripts" toggle. • Clear feedback: Keysmith tells you when a shortcut is already taken, or when Chrome reserves a combination (like Ctrl+T) that no extension can override. • Autosave: every change is saved instantly. • Moving from Shortkeys? Import your Shortkeys export file in one click. Anything we can't map is listed, never silently dropped. • Private by design: no accounts, no tracking, no analytics, no remote code. Your settings stay in your browser (synced by Chrome if you use sync). WHAT YOU CAN DO • Tabs: next / previous / first / last, jump to tab 1–9, last-used tab, new tab (or to the right), duplicate, close, close others / left / right, reopen closed tab, pin, mute, move left / right / to a new window • Windows: new window, new incognito window, close window • Navigation: back, forward, reload, hard reload, open a URL, open a bookmark, copy page URL, copy title + URL as a Markdown link • Scrolling: line, page, top, bottom — hold the key to keep scrolling • Zoom: in, out, reset • Video (YouTube and any HTML5 video): play/pause, speed up / down / reset, skip ±5 seconds • Block a site's own shortcut with a "Do nothing" action SMART CONTROLS • Per-site rules: run a shortcut everywhere, only on certain sites, or everywhere except certain sites • Choose whether a shortcut works while you're typing in text fields • Match by physical key position (great for non-QWERTY layouts) or by the typed character • Export and import your settings as a file GOOD TO KNOW Chrome does not allow extensions to run on chrome:// pages, the Chrome Web Store, or the New Tab page, so shortcuts are paused there.
