description: "A free macOS utility that overlays every keyboard shortcut for the frontmost app when you double-tap and hold Command, a free alternative to CheatSheet or KeyCue."
---

Double-tap and hold Command and KeyClu overlays every shortcut the frontmost app exposes through its menu bar, so you stop guessing whether it's Cmd-Shift-K or Cmd-Option-K. It fills the same niche as CheatSheet or KeyCue, just free and open-source, installable via Homebrew or a plain DMG. Its own changelog admits the honest limit: shortcuts hidden behind icon-only menu items won't show up, only what the app's menu bar actually lists.
