bug#631: the M- notation suggestion


From: xah lee
Subject: bug#631: the M- notation suggestion
Date: Mon, 4 Aug 2008 04:33:01 -0700

The change suggested is only about in emacs manual, emacs tutorial, and in menus.

There is no proposal to change emacs lisp's keyboard macro or elisp functions.

This is not true.  There are many places in the Emacs Lisp code which
recognize the M- and C- notation.

First, there is the read syntax (I'm using Emacs 22.1):

  ?\M-A ⇒ 134217793
  ?\M-\C-b ⇒ 134217730

  "\M-A" ⇒ "\301" (yes, this is a bit different behavior for M-A)

Then, there is the convention of making symbol names with prefixes for
use in key bindings:

  M-f3
  M-mouse-1
  M-drag-mouse-2
  M-double-mouse-2

Then, there is the lovely kbd macro for use in key bindings:

  (kbd "C-M-<down>") ⇒ [C-M-down]

Then, there is the use of the M- and C- notation by edit-kbd-macro.

Then, there are the key-description, single-key-description, and
read-kbd-macro functions:

  (key-description [?\M-3 delete]) ⇒ "M-3 <delete>"

There is also the text-char-description function.
