So I flashed my keyboard firmware with the provided tool and it’s very nice to have fn+trackball to scroll and volume works as expected. But for my project I’d like to have trackball to be permanently in scroll mode without needing to hold fn. What would be my steps to achieve that? Something like fn+s to set the scroll mode and again fn+s to turn it off.
Ideally I’d wish to have this feature turned off/on. I tried keyd daemon but remapping fn key isn’t possible with it. So I guess my only option is custom firmware.
