Subject: 24.2; Cannot discover automatic-all or other multi-buffer replacement
	commands
Date: Mon, 15 Oct 2012 12:40:46 +0100

While investigating a problem, I happened to notice a ChangeLog entry
referring to multi-query-replace-map, which led me to the automatic-all
function, which happens to be something I had regularly felt the lack
of.

I was able to find a reference to it in the NEWS for Emacs 23.1, but
that again was at the Lisp level; nowhere can I find user documentation
for this handy feature. In particular, C-h m does not mention the extra
multi-query-replace-map keystrokes when one is running, for example,
tags-query-replace.

I bet I'm not the only user who would love this feature but has never
come across it; ideally it would also be documented in the manual, but
making its documentation appear when describe-mode is run would at least
make it discoverable.

In http://debbugs.gnu.org/267#15   I proposed to document this feature
in the help message displayed by `C-h'.

But you mentioned `C-h m' (`describe-mode').
Do you mean to describe this feature in the docstrings of
`tags-query-replace', `dired-do-query-replace-regexp',
`vc-dir-query-replace-regexp' and `reftex-query-replace-document' ?

`automatic-all' is already documented in (info "(elisp) Search and Replace")

Do you think it should be also documented in (info "(emacs) Tags Search") ?

Then (info "(emacs) VC Directory Commands") should link to the node
(info "(emacs) Tags Search") like (info "(emacs) Operating on Files") already does.
With these links, this feature could be documented just in one Info node.

No. That would seem a bad place, as it would duplicate information
manually. It should be somewhere that is controlled by the multifile
map being hooked into the keymap. The place that documents the current
keymap, i.e. the mode help, seems to be a logical place for this.

That is elisp coding documentation, not Emacs user documentation.

Might it be more logical to mention it in the documentation "(emacs)
Query Replace", where all the other keystrokes are documented?

Then the right place to document it is in `query-replace-help':

Right, with a link from (info "(emacs) Tags Search") to

this can be documented in (info "(emacs) Query Replace"):
