Need a hand?

It depends on the feature switch. When it is on, clicking Close hides the control window and Dock icon while gesture detection continues in the background. When it is off, clicking Close ends the app. The switch takes effect immediately and remembers your choice.

Open CmdFlick again from the Applications folder in Finder to return to the same control window. The window stays open when you visit System Settings. While the control window is visible, Command-Q and a normal Quit from the Dock follow the same rule. System requests to quit and reopen still end the process.

Press and release Command fully each time. Hold each press for no more than 0.25 seconds and leave no more than 0.35 seconds between releasing the first tap and pressing the second. Both taps must use the same key. Long presses, alternating sides, or holding both Command keys will not trigger the gesture.

The app needs to recognize the gesture while other apps are in the foreground, and rule out ordinary shortcuts and mouse actions. It handles only necessary key codes, states, and timing. It does not extract typed text or save or upload keystrokes. Read the full privacy policy.

1. Open CmdFlick again. If the permission section is shown, allow Input Monitoring first, then turn on Enable double-Command. If the switch is already on, granting permission enables monitoring automatically. Showing the control window does not pause the gesture.
2. Use the same Command key twice without other keys, clicks, dragging, or scrolling between taps.
3. If you moved the app or changed its signature, check whether permission needs to be granted again.
4. Check the monitoring status in the control window or any Spotlight error. To restart the app, turn the feature off and click Close, then reopen CmdFlick and switch it on again.
5. Check Spotlight itself using the macOS system shortcut. CmdFlick does not change Spotlight’s settings.

A password field or another app may enable macOS Secure Input. CmdFlick pauses global gesture monitoring while that protection is active. Leave the secure input context, wait a moment, and try again; reopen CmdFlick if necessary. There is no need to disable system security features.

Monitoring is read-only: input is not suppressed or changed. Ordinary keys, other modifiers, mouse actions, and long presses cancel a pending gesture. Three consecutive taps produce only one double tap. Caps Lock being on does not affect the gesture.

Turn on the Launch CmdFlick when I log in switch to apply the setting immediately; turn it off to disable login startup. It is off by default and independent of the feature switch. If macOS requests approval, review it in System Settings → General → Login Items & Extensions. Future login launches stay silent and use the remembered feature switch state.

To quit completely, turn off Enable double-Command, then click Close. This preserves the login setting. To also prevent the next login launch, turn off the launch-at-login switch first. No separate daemon restarts the app.

The app supports Simplified Chinese and English and follows your system’s preferred language automatically. Other languages use English. There is no separate language setting in the app.

CmdFlick is available as source code under GPLv3 (GPL-3.0-only), so you can build it on your Mac. A paid Mac App Store download is planned. Both focus on the same double-tap feature; the store option saves you the build steps. Store availability and pricing have not been announced.
