I quite liked the coordinate system proposal. I can propose this: Vendor maps the keyboard lights to a grid. That would be something 16x8 for thinkpad X220. Then we provide functionality to query "is a working pixel there" and "what kind of key is at this pixel" -- I guess we can use input keycodes for that. Multiple pixels can map to one keycode. (And then we make best effort to map normal keyboards into similar grids). Best regards, Pavel -- People of Russia, stop Putin before his war on Ukraine escalates.
