Can you determine what USB HID code(s) the scanner is sending for that? (Perhaps using wireshark, or usbmon on linux, …) Some years ago I worked on ChromeOS keyboard input, and I can probably tell you right away what it'd do with it. Basically, is the USB code in https://source.chromium.org/chromium/chromium/src/+/main:ui/events/keycodes/dom/dom_code_data.inc https://source.chromium.org/chromium/chromium/src/+/main:ui/... Alternatively (but probably less usefully), try it on https://w3c.github.io/uievents/tools/key-event-viewer.html https://w3c.github.io/uievents/tools/key-event-viewer.html
