A little tip that may help with finding the documentation for zsh
built-ins:

	if ((${+aliases[run-help]})); then unalias run-help; fi
	autoload -Uz run-help

This will make the run-help command available, which will present the
manual page for the command that you give it as an argument (including
the correct documentation for zsh built-ins).  According to the run-help
source code: "Figure out where to get the best help, and get it."
