Subject: Better sorting for describe-bindings and describe-mode
Date: Tue, 23 Apr 2024 18:04:27 +0800

I discovered that
C-h m describe-mode and thus also
C-h b describe-bindings
are several times more helpful, if sorted by the last field, not the first.
E.g., for
$ emacs file.html #then C-h m and save to a file and pipe it to
grep --perl-regexp \\t | expand | sort -k 1.16 #giving:

C-c C-a         sgml-attributes
C-c /           sgml-close-tag
C-c C-e         sgml-close-tag
C-c ]           sgml-close-tag
C-c C-d         sgml-delete-tag
C-c DEL         sgml-delete-tag
C-c C-n         sgml-name-char
C-c <left>      sgml-skip-tag-backward
C-c C-b         sgml-skip-tag-backward
C-c <right>     sgml-skip-tag-forward
C-c C-f         sgml-skip-tag-forward
/               sgml-slash
C-c C-o         sgml-tag
C-c C-t         sgml-tag
C-c ?           sgml-tag-help

Allowing the user to suddenly see all the alternate bindings in a glance.

Therefore I propose C-h b and C-h m start listing them that way, or at least offer an option to do so. Thanks.

Wait, hold on. Let's examine the default sort order.

...
C-c <left>	sgml-skip-tag-backward
C-c <right>	sgml-skip-tag-forward

C-M-i		ispell-complete-word

M-o M-o		font-lock-fontify-block

C-c C-c #	html-id-anchor
C-c C-c -	html-horizontal-rule
C-c C-c c	html-checkboxes
...

We see that there is no default sort order.
It's all just glued together as processing proceeded.
Even more reason to use my brilliant proposed order.
