Subject: 23.0.60; Accented character input on OS X doesn't work right
Date: Tue, 16 Dec 2008 11:21:07 -0800

It seems like some modifiers are lost when using the standard OS X  
accented keys.

e.g. hitting Option+[ inserts U+201C LEFT DOUBLE QUOTATION MARK, and  
Option+Shift+[ inserts U+201D RIGHT DOUBLE QUOTATION MARK. However, in  
Emacs, Option+Shift+[ inserts U+007B LEFT CURLY BRACKET, as if the  
Option modifier wasn’t pressed.

Further, the Option modifier is lost when using Meta (which I have  
mapped to the Command key). For example, I have M-“ bound to (insert- 
pair):

(define-key ime-bindings-map [?\M-“] 'insert-pair)

When I press Opt-M-[, I get a pair of square brackets, as if I hadn’t  
pressed the Option key at all.

Note that I also have M-[ bound to (insert-pair):

(define-key ime-bindings-map "\M-[" 'insert-pair)

I cannot replicate this using either a Macbook Pro keyboard in US  
layout or a PC keyboard connected via USB, same layout.  What kind of  
keyboard are you using and what is your system input method set to?   
Could you make sure this still happens when you run emacs by:

/Applications/Emacs.app/Contents/MacOS/Emacs -Q

thanks

Okay, a few things going on here. First off, I’m using the built-in  
keyboard on a US MacBook Pro. I’m using the standard US English  
layout. The only exotic thing I’ve done is remapped Caps Lock to be  
Control (in System Preferences -> Keyboard & Mouse -> Keyboard ->  
Modifier Keys).

Firstly: A bunch of settings are stored in ~/Library/Preferences/ 
org.gnu.Emacs.plist. Even if I start Emacs with -Q, these settings are  
applied. This seems wrong.

The problem happens when the following two conditions are met:

1. In Emacs -> Preferences -> Modifiers, Alt key is set to "None."
2. In custom-set-variables defines: '(ns-alternate-modifier nil t)

I removed the customized var, as the docs for it indicated that it  
wasn't customizable, and things work again.
