alt Hacker NewsI was missing it too. Google says it's a builtin zsh feature but mac doesn't turn it on by default, so you add these to `~/.zshrc`
bindkey '^[[A' history-search-backward
bindkey '^[[B' history-search-forward
I'm not really sure what "turn it on by default" even means in the context of a shell. I've had that manually in my config for years.
