Thank you both for pointing me in the right direction.
As I want usually want at least one terminal (interactive) instance open, I wanted to mimic
activate kitty.app without the special KM variables in my main interactive session. Personal preference, I guess, aligning with the philosophy of using local variables in KM as well.
Currently, the other alternative to unsetting variables I see is to just open a terminal, run my command (
/usr/local/bin/kitty --bunch-of-flags), but I can't close the parent shell, otherwise it would terminate my kitty instance. I know it's going off topic now, but Google searches led me to the
disown commands, but honestly I'm at my limits.
Which leads me to a general, final question: is there a native way to run background scripts preferably via hotkeys?
