Keystroke for background active application

With SONOS Application launch in background, I would like to invoque a keytroke to change for previous track, for example.
Is it possible with KM?

Thank you for your help…

:wink:

It is indeed possible as long as you're using KM8 or later, though reliability is not 100% guaranteed since macOS expects apps receiving keystrokes to be at the front. Click the gear menu in a "Type a Keystroke" action and look for the "Send To" submenu:

You are my hero !..

Merci beaucoup pour votre aide et très belle fête de fin d’année… from Paris !.. :wink:
