Laser · Stream Deck plugin
Every key lands in LightBurn and only LightBurn. It brings the app to the front first and never fires into whatever else is open.
On the Elgato Marketplace
LightBurn 2.1.04 on macOS 13 or later, and Stream Deck software 6.9 or newer. The Stream Deck app needs Accessibility permission to send keystrokes; macOS asks once.
