- This section briefly describes the peculiarities of using Emacs built with
-the GNUstep libraries on GNU/Linux or other operating systems, or on Mac OS X
-with native window system support. For Mac OS X, Emacs can be built either
-without window system support, with X11, or with the Cocoa interface. This
-section only applies to the Cocoa build. Emacs 23 does not support Mac OS
-Classic.
-
- Emacs, when built on Mac OS X, uses the Cocoa application interface. For
-various historical and technical reasons, Emacs uses the term @samp{Nextstep}
-internally, instead of ``Cocoa'' or ``Mac OS X''; for instance, most of the
-commands and variables described in the following sections begin with
-@samp{ns-}, which is short for @samp{Nextstep}. NeXTstep was an application
-interface released by NeXT Inc during the 1980s, of which Cocoa is a direct
-descendent. Apart from Cocoa, there is another NeXTstep-style system:
-GNUstep, which is free software. As of this writing, the GNUstep support is
-alpha status (see @pxref{GNUstep Support}), but we hope to improve it in the
-future.

@section Basic Emacs usage under Mac OS and GNUstep

-
By default, the @key{alt} and @key{option} keys are the same as
-@key{Meta} when running under Mac OS. The Mac @key{Cmd} key is the
-same as @key{Super}, and Emacs provides a set of keybindings using
-this modifier key that mimic other Mac / GNUstep applications (@pxref{Mac /
-GNUstep Events}). You can change these bindings in the usual way (@pxref{Key
-Bindings}).
-
- The standard Mac / GNUstep font and color panels are accessible via the
-@samp{Windows} menu, or via the standard @key{Cmd-t} and @key{Cmd-C}
-keybindings. To use the color panel, drag from it to an Emacs frame

+
+ The variable @code{ns-right-alternate-modifier} controls the
+behavior of the right @key{alt} and @key{option} keys. These keys
+behave like the left-hand keys if the value is @code{left} (the
+default). A value of @code{control}, @code{meta}, @code{alt},
+@code{super}, or @code{hyper} makes them behave like the corresponding
+modifier keys; a value of @code{none} tells Emacs to ignore them.
+
+ The standard Mac / GNUstep font and color panels are accessible via
+Lisp commands. To use the color panel, drag from it to an Emacs frame
to change the foreground color of the face at that position (if the
@key{shift} key is held down, it changes the background color

-@samp{Save Options} in the @samp{Options} menu. To discard the
-settings, create a new frame and close the altered one.

@key{S-Mouse-1} (i.e., clicking the left mouse button
while holding down the @key{Shift} key) adjusts the region to the
@key{S-Mouse-1} normally does (@pxref{Temporary Face Changes}). This
change makes Emacs behave more like other Mac / GNUstep applications.

+ When you open or save files using the menus, or using the
@key{Cmd-o} and @key{Cmd-S} bindings, Emacs uses graphical file
dialogs to read file names. However, if you use the regular Emacs key
sequences, such as @key{C-x C-f}, Emacs uses the minibuffer to read

+Many programs which may run under Emacs, like latex or man, depend on the
settings of environment variables. If Emacs is launched from the shell, it
will automatically inherit these environment variables and its subprocesses
will inherit them from it. But if Emacs is launched from the Finder it
is not a descendant of any shell, so its environment variables haven't been

+set, which often causes the subprocesses it launches to behave differently than
they would when launched from the shell.
-To solve this problem for Emacs, there are two solutions. First is to
-run, from the command line:
-
-@example
-.../Emacs.app/Contents/MacOS/bin/mac-fix-env
-@end example
-
-This will pick up your environment settings and save them into a special file
-@file{~/.MacOSX/environment.plist}, which the desktop environment will use to
-set the environment for all launched applications. The drawback of this
-method is it needs to be run again whenever something changes.
-
-The other approach is to use the @code{ns-grabenv} command inside Emacs. This
-function will run a subshell and copy its environment variables into Emacs.
-
-Adding this line to your @file{~/.emacs} will grab the csh environment
-whenever emacs runs under a window system.
-
-@lisp
-(if window-system (ns-grabenv))
-@end lisp
-
-If you have a different shell you will have to give @code{ns-grabenv} some
-arguments. For zsh you would do this.
-
-@lisp
-(if window-system (ns-grabenv "/usr/bin/zsh"
- "source /etc/zshenv"
- "source ~/.zshenv"))
-@end lisp
-
-The reason that @code{ns-grabenv} is not done by default is that it adds up
-to a second or two to the Emacs startup time.
-
+For the PATH and MANPATH variables, a system-wide method
+of setting PATH is recommended on Mac OS X 10.5 and later, using the
+@file{/etc/paths} files and the @file{/etc/paths.d} directory.

Emacs can be customized in several ways in addition to the standard
customization buffers and the Options menu.
-In addition, redundancy in the menus can be reduced and more shortcuts

@subsection Font and Color Panels
-The Font Panel may be accessed from the Windows menu or by @kbd{Cmd-t}. It

-Emacs can be built and run under GNUstep however building is difficult and
