+*Edit 2024-09-09: Please be advised that this post refers to an older version of `keyd` that still used a different configuration format. An older version also stated the config file was stored at `~/.config/keyd`, that was an error on my part. Thanks to a reader for the related heads-up!*

 As a German living in Germany with umlauts in my last name and a US ANSI keyboard layout on all my devices[^1] I need to remap some stuff to be able to easily type ä, ö, ü and ß. On Windows I solved this with [Autohotkey](https://www.autohotkey.com/), mapping `AltGr`+`a` to `ä`, `AltGr`+`o` to `ö`, `AltGr`+`u` to `ü` and `AltGr`+`s` to `ß` (well, technically `RAlt` - the right `Alt` key). That has burned itself into my muscle memory now, and so while currently setting up my new Framework laptop under Linux, with Gnome running on Wayland, I was looking for a way to remap the keys to this layout as well.
 
 In the old days, I would have written an `.Xmodmap` file and called it a day, but that no longer works under Wayland. Thankfully however there's a whole new generation of mapping tools that instead of depending on the X server allow remapping right at the kernel input level, and one of them is [keyd](https://github.com/rvaiya/keyd) which I used to solve my umlaut problem, and while at it also added a fancy mod layer and even a mouse layer.
