After exploring all solutions, and fighting a few things to build either Hawck or Espanso on openSUSE (I’m not a dev), I finally managed to find instructions to get Espanso to build (it’s all there, fellow desperate random reader of the future). Since you can define the keyboard layout AND the variant of said keyboard you are using with Espanso, it’s working as expected.
So now, I’ve associated “:$” with “|>”, not sure how well that’ll work in the future, but it’s far easier to type on my keyboard at least… Also, I gained a tool to insert greek symbols and smileys everywhere that I didn’t know I needed, but very quickly adopting! 😅
