KeyCue shows your shortcuts. HotkeyClash finds where they clash.

Different tools for different questions

KeyCue (and the free KeyClu) answers: “What shortcuts does this app offer?” Hold a modifier and an overlay lists everything available — a genuinely useful cheat sheet, especially while learning a new app.

HotkeyClash answers a different question: “Why doesn’t my shortcut work, and where do my apps fight over keys?” A viewer can’t answer that — it shows each app’s shortcuts in isolation, and it doesn’t see global hotkeys from launchers, window managers, or Karabiner rules at all. Conflicts live exactly in those gaps.

Where KeyCue genuinely wins

If you want a polished, always-available shortcut reference with themes and emoji search, buy KeyCue — or try KeyClu first, which covers the basics for free. Ergonis has maintained KeyCue for two decades and it shows.

Where it can’t help you

When ⌘⇧5 suddenly opens your screen recorder instead of taking a screenshot, a cheat sheet shows you two apps that both list the combo — and leaves the diagnosis to you. KeyCue costs about $25/year with upgrade pricing, runs as a closed-source binary with Accessibility access, and detecting conflicts was never its job.

HotkeyClash groups every binding from every source by key combination, flags combinations claimed more than once, and classifies how badly they clash. It’s the diagnostic tool; KeyCue is the reference card.
