Keyboard and Trackball firmware mod

I have found some of the default bindings on the keyboard to be rather annoying and I wish to change them ( I want to replace left alt with super and make function trackball scroll wheel) how do I go about performing this mod.

I think the easiest way is to install a modified QMK firmware, it’s pretty easy to modify those keymaps

I mean how do I modify the firmware the website mentions an arduino environment and micro-USB but other than that I dont know how I modify it.

  1. you need to update your keyboard firmware version, instructions are in their github
  2. you can switch to QMK and have select + ball for scroll

in X11 you can do it via xkb https://unix.stackexchange.com/questions/86933/swap-alt-and-super#367016

have no idea how to handle it in wayland, check your DE/WM documentation (all hail wayland)

Keyd is also great for this

Works for both X11 and wayland

Thanks to the 3 that replied I just got round to it keyd is what I used, no issues (unlike almost everything else) would definitely recommend it though I havent gotten round to the trackball scroll the wiki is a bit vague sometimes hopefully chatgpt will help
