Launch App
How this Rule works
The example uses Option-Space to launch Safari with no Condition. Select your app and an unused shortcut in the Rule.
Configure and try it
Import the Rule, review its Trigger and Actions, and adjust the settings described above before enabling it. Test the result in a safe, temporary context.
Requirements and limits
Allow Accessibility for the shortcut and test with the app closed and already running. This sample contains Launch Application only; it does not include a separate focus Action.
