Yes, thank you for that.

Apparently you agree that the rule for function keys is lowercase.
Yet you leave some of them capitalized or uppercase?  And the reason
is because those that you make lowercase are symbols?

The convention used should be the one that Emacs itself uses to
write key sequences.

(And yes, this discussion is outside this bug report.  I did not
ask in the report that you fix all key-sequence inconsistencies in
the manual.  But that's what the current discussion is about.
That and the inconsistencies between the notations in the manual
and the notation in the Emacs UI.

1. Yes, it is outside this bug report.
2. Too bad you are not interested in it, but so be it.

You fixed only some inconsistencies in the manual, but that is OK
for this bug report.  It is inconsistent to use <BACKSPACE> sometimes
and <Backspace> other times, <DELETE> and <Delete>, <left> and <Home>,
and so on.

But yes, beyond inconsistencies within the manual, the larger issue is
to get the manual in sync with the rest of Emacs, so there it uses the
same, single, key-sequence notation.  And yes, that is outside this
bug report.

I am OK with (what I guess is) what you have fixed for this bug report.

Thank you for that.
