So I moved from Windows to Ubuntu. I looked around but couldn't find it. I'd need to add keybindings:
Alt Gr-] woult bind to õ
. Shift-Alt Gr-[ to Ü
etc.
How would one achieve this monstrosity?
This monstrosity is achieved by a tool called Xmodmap. You will need to create a file, called .Xmodmap
in your home directory. Search over the net for instructions on how to fill it.
Many xmodmap manuals tell you to run it manually - you don't need to, the file will be applied on relogin automatically.
