I just figured out how to do this:

$ zhelp() { man zshbuiltins | less -p "^       $1" }

$ zhelp read

      read [ -rszpqAclneE ] [ -t [ num ] ] [ -k [ num ] ] [ -d delim ]
             [ -u n ] [ name[?prompt] ] [ name ...  ]
      ....

... simple and effective, but I'll bet someone has something better.

you should try typing
read (or any other command) than pressing alt-h, by default bound to the
run-help widget

I think something got lost when I switched to the 'official' Debian copy 
of zsh.  I do remember run-help being useful but it doesn't work now, it 
reports as being an alias of 'man'.  And somebody has stolen the alt-h 
key, I think xfce owns it now, it brings up a graphical box that shows 
me an 'about' for the xterm. Mind I can probably steal it back.  If I 
can get run-help useful again.

Add this to .zshrc:

    autoload -Uz run-help

    if [[ -v aliases[run-help] ]]; then
     unalias run-help
    fi

You need
 unalias run-help
 autoload run-help
somewhere.

Tried that, no action.  In my downloaded zsh I have:

.../functions/run-help

In Debian's version:

.../functions/Misc/run-help

... but running it (sourcing it) directly from there it seems to work fine.

Ah! ... what is it ... zsh's internal path, can't remember what it's 
called but it finds this sort of thing.  Maybe my configuration isn't 
set to find it in 'Misc' -- why would Debian decide to put things where 
zsh devs don't want them to be anyway? You guys know where you want 
things, why not leave it alone?

% which zman
zman () {
	PAGER="less -g -s '+/(?i)^       "$1"'" LANG= man zshall
}

I, personally, don't find read-help that useful (which is suggested in 
the other branch of this tread).
Try `run-help run-help` which says that there is nothing to be found, 
whereas `zman run-help` shows me what I need :)

I'll play with that, thanks.
