Zsh Autosuggestions

I used zsh for couple of years, and then switched to fish mainly for its built-in autocompletion. fish is a modern shell (just like helix) and thus (I think) it does several things differently. For someone using various shells for over 2 decades, resisting muscle memory does not come easy. 1 I was used to export KEY=value, so in fish I always had to look up How to set an environment variable in fish 😆 - even after 2 years.
