LaTeX-math-keymap's value is shown below.
Keymap used for `LaTeX-math-mode' commands.
Defined in `latex'.
Value:
(keymap
(menu-bar keymap
(math menu-item "Math"
(keymap "Math"
(cal-whatever menu-item "Cal-whatever" LaTeX-math-cal
([96 99]
. " (` c)"))
(greek menu-item "Greek"
(keymap "Greek"
(γ\ \\gamma menu-item "Γ \\Gamma" LaTeX-math-Gamma
([96 71]
. " (` G)"))
(δ\ \\delta menu-item "Δ \\Delta" LaTeX-math-Delta
([96 68]
. " (` D)"))
(θ\ \\theta menu-item "Θ \\Theta" LaTeX-math-Theta
[...]
(greek menu-item "greek"
(keymap "greek"
(α\ \\alpha menu-item "α \\alpha" LaTeX-math-alpha
([96 97]
. " (` a)"))
(β\ \\beta menu-item "β \\beta" LaTeX-math-beta
([96 98]
. " (` b)"))
(γ\ \\gamma menu-item "γ \\gamma" LaTeX-math-gamma
([96 103]
[...]
Now it is obvious that the identifying symbols before the menu-items
are being downcased from their respective menu strings, and that we
get duplicate symbols this way.
Who is doing the downcasing?
We start from the variable LaTeX-math-menu defined as
LaTeX-math-menu's value is shown below.
Menu containing LaTeX math commands.
The menu entries will be generated dynamically, but you can specify
the sequence by initializing this variable.
Defined in `latex'.
Value:
("Math"
["Cal-whatever" LaTeX-math-cal t]
("Greek"
["Γ \\Gamma" LaTeX-math-Gamma t]
["Δ \\Delta" LaTeX-math-Delta t]
["Θ \\Theta" LaTeX-math-Theta t]
["Λ \\Lambda" LaTeX-math-Lambda t]
[...]
("greek"
["α \\alpha" LaTeX-math-alpha t]
["β \\beta" LaTeX-math-beta t]
["γ \\gamma" LaTeX-math-gamma t]
when creating the menu. This menu gets added with
(easy-menu-define LaTeX-math-mode-menu
LaTeX-math-keymap
"Menu used in math minor mode."
LaTeX-math-menu)
The symbols that easy-menu-define chooses obviously get downcased from
the respective menu strings, probably in order to provide a more
pleasing appearance or whatever.
Tracing this back in easymenu.el, we eventually arrive at
(defsubst easy-menu-intern (s)
(if (stringp s) (intern (downcase s)) s))
Looking in the CVS logs, we arrive at
revision 1.47
date: 2002/04/24 23:18:42; author: rms; state: Exp; lines: +38 -21
(easy-menu-intern): Downcase before interning.
(easy-menu-define-key-intern): Function deleted; callers intern
and then call easy-menu-define-key.
(easy-menu-do-add-item): Explicitly intern the key, but not BEFORE.
(easy-menu-define-key): Use easy-menu-name-match to match BEFORE.
(easy-menu-name-match): New function.
(add-submenu): New function.
(easy-menu-get-map-look-for-name): Use easy-menu-name-match.
----------------------------
So the main question is: what is the purpose of this change other than
the bad effects I am now experiencing?
If it should be disallowed to use menu entries that differ only in
case, then this needs to get documented somewhere.
