I also use zsh for years and did not know that. What I like this: Actually having completions shown in the screen and being able to navigate them with tabs. I think that is not a default behavior, but that is what oh-my-zsh does for you in its default setup. Does someone have more insight on that?

I did not know about this, but I use https://github.com/wting/autojump, so I am not super sad that I missed something that hold me back severely. But good to know.
