[Message part 3 (text/plain, inline)]
Emacs Maintainers,
The following two issues concerning Query Replace were
found in GNU Emacs version 27.1, started with 'emacs -Q':
1. It appears that it is not possible to display the options
available when using `query-replace' (M-%).
According to the Emacs manual at (emacs)Query Replace:
----
‘C-h’
‘?’
‘<F1>’
to display a message summarizing these options. Then you must type
another character to specify what to do with this occurrence.
----
Yet when any of these three keys are pressed after the
"Query replace: " prompt is displayed in the minibuffer,
there is no *Help* buffer displayed. Based on the text in
the manual, above, shouldn't we expect to see a help buffer
displayed with a summary of the keybindings for
`query-replace'?
A cursory look inside replace.el shows that it has the
DEFCONST `query-replace-help' defined to provide the
information that is described in the Emacs manual, but this
function is not being called when one of the keys C-h, [F1],
or ? is pressed.
2. The DEFCONST `query-replace-help' describes 'E' (upper-case
e) as:
----
E to edit the replacement string.
----
But the Emacs manual at (emacs)Query Replace describes 'e'
(lower-case e) as:
----
`e'
to edit the replacement string in the minibuffer. When you exit
the minibuffer by typing <RET>, the minibuffer contents replace the
current occurrence of the pattern. They also become the new
replacement string for any further occurrences.
----
In replace.el, the DEFVAR `query-replace-map' has both e and
E mapped to `edit-replacement'. So both keys should work,
but neither the help text nor the info manual document thatboth keys can be used.
Note: The following search did not find the above issues inthe GNU Bug Tracker:

This citation is incomplete: you've taken one item from a long list of
characters one can type, and that list begins with this text:
The characters you can type when you are shown a match for the string
or regexp are:
So the Help character will work if you type it after you already
provided the string to replace and its replacement, and Emacs shows
you the first match -- which is when this help is relevant. You don't
need this help earlier because none of those characters can be used
before the first match is found.

I added 'E' to the text in the manual on the emacs-27 branch.
With that, I'm closing this bug report. Thanks.
