If you can’t get Vicreo Listener (https://www.vicreo-listener.com) to simulate keystrokes on your Linux machine via Companion app (https://bitfocus.io/companion/), instead of using the key press action, use the Send shell command option to send a xdotool command (https://www.xmodulo.com/simulate-key-press-mouse-movement-linux.html).
e.g., on press, send VICREO hotkey: Send shell command: xdotool key n (to proceed to the next slide in your slides.com presentation) ;)
PS. Join us live today on Small Is Beautiful at 5PM Irish time to hear about what we’ve been up to, including my work on elementary OS and on removing the Mac from my streaming setup (oh, that client-side scanning is going to cost you more than just my business, Apple) ;)
This is my personal Mastodon.
