zsh-syntax-highlighting: unhandled ZLE widget 'history-substring-search-up'

[XXiaoA]

I used zinit to download zsh-history-substring-search and added the following bindkey like the document

bindkey '^[[A' history-substring-search-up

Unexpectedly, zsh threw some messages, although I never used zsh-syntax-highlighting

zsh-syntax-highlighting: unhandled ZLE widget 'history-substring-search-up'

BTW, I am using fast-syntax-highlighting

And, there is my all configuration

EDIT: According to my google results, it seems that bindkey should be put after source zsh-syntax-highlighting. However, I never use zsh-syntax-highlighting. So it pretty confuse me🤨

So you're saying that zsh-syntax-highlighting runs and you don't know why? That's a bug either in zinit or in your dotfiles, not in zsh-syntax-highlighting.

Good luck.
