How can I toggle fold, open all folds, and close all folds within the Doom Docs?
I'm familiar enough with vim, but recently installed doom emacs. I found the potentially helpful `SPC h d s` for searching the doom help. I can't figure out how to get any one, or all of, the headlines to unfold.
For example, `SPC h d s` followed by a search for "buffer" takes me to :emacs ibuffer. `z R` manages to unfold "\*1 Description". I then try all sorts of `z R`, `z o`, and whatever other bindings I can find mentioned in `SPC h b b` under "fold", but I can't get the other folds to open.
