Hi @LimpinAintEZ, thanks for the tip. Years ago I had installed a similar app called "Actions for iPad" and later "Quattro". Due to exaggerated subscription prices, this app doesn't do well anymore.
A free alternative is Apple's own Shortcuts app. In this article just an example how I lock and unlock my Macs via Siri and Keyboard Maestro. This can be done via a voice command as well as via the Touch in the Shortcuts app
When I mirror my macOS to the TV via Air Play, I use the BTT Remote App, because I can also make text entries with it and have a cursor control available.
The setup and functionality is however identical to the Shortcuts app.
The possibilities in combination with Keyboard Maestro are simply ingenious, because you can only use the AppleScript of the macro and later change the macro as you like, without having to change the carrier (Applescript).
