As answered by people managing Codility and HKeys.app.
HKeys.app's answer:
Professionals and power users who work across multiple apps and want to build faster, more efficient workflows. Designers, developers, students, writers, and anyone switching between tools or platforms who needs an accurate, quick shortcut reference — without digging through documentation or app menus.
HKeys.app's answer:
HKeys started as a personal frustration: shortcut references were scattered, platform-specific differences were ignored, and most cheat sheets were static PDFs that went out of date. HKeys was built to be the reference that actually works — organized by app and platform, kept current, and free to access.
HKeys.app's answer:
HKeys organizes shortcuts by platform, not just by app. Most shortcut references give you one flat list — HKeys gives you a separate, accurate page for each platform an app runs on (macOS, Windows, Linux, iOS, web), because the key combinations are actually different. Every page also includes a platform switcher, multiple view modes (Full, Short, Icon), and a downloadable free PDF cheat sheet.
HKeys.app's answer:
HKeys covers a wide range of apps across every major platform in one place — design tools, browsers, office apps, developer tools, communication and productivity apps, and operating systems. The catalog is free to browse without an account, shortcuts are organized per platform so you always see the right key combinations for your OS, and every page has a printable PDF cheat sheet available to free account holders.
