Hooking up Emacs's Info to find Homebrew's info

[pedz]

I use zsh on a Mac (as most of us do) and the zshall man page is a frequent reference I must use. But I knew from the past that zsh had info and it wasn't in the info directory when I did ^H i in Emacs. So, after about two hours or research and head scratching, it is drop dead easy to hook up. I thought I would share.

The variable is Info-additional-directory-list. It does not exist until you start info once. Then you can customize it with /opt/homebrew/share/info. I'm not 100% sure but I think you need to quit and restart emacs to get it to take effect.

Enjoy!
