Currently, you can swap the position of casual parenthesis with casual brackets. I suggest to add one option to change its position with curly ones as well. http://funkyimg.com/i/2LvXn.png Thanks a lot
These options come from XKB itself; you would have to submit a merge request at https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/merge_requests/ However I tried doing this recently and got rejected: https://gitlab.freedesktop.org/xkeyboard-config/xkeyboard-config/-/merge_requests/186 I get the sense that they aren't interested in adding any new options and they seem to think that the number of existing options available was a mistake.
