I kept losing time looking up keyboard shortcuts. Not dramatically — just the slow accumulation of opening a tab, landing on the wrong page, finding a forum post from 2018, and locating the right shortcut four minutes later. Annoying enough to build something.

hotkeycheatsheet.com is a searchable reference: 134 apps, 24,126 shortcuts, organized by category. Filter by OS (Windows, macOS, Linux) and search by app name, action, or partial key combo — "ctrl k" works, so does "cmd shift".

I tried to keep it fast and single-purpose. Whether that actually worked is what I'm most curious about — happy to hear what feels off or missing.
