Inside Emacs, the command @kbd{M-x getenv} gets the value of an
environment variable. @kbd{M-x setenv} sets a variable in the Emacs
-environment. The way to set environment variables outside of Emacs
-depends on the operating system, and especially the shell that you are
-using. For example, here's how to set the environment variable
-@env{ORGANIZATION} to @samp{not very much} using Bash:

+variable yourself unless your installation is non-standard, since
+unlike other environment variables, it will be overridden by Emacs at
+startup. When setting other environment variables, such as
+@env{EMACSLOADPATH}, you may find it useful to use @env{emacs_dir}
+rather than hard-coding an absolute path. This allows multiple
+versions of Emacs to share the same environment variable settings, and
+it allows you to move the Emacs installation directory, without
+changing any environment or registry settings.
+@end table
+
+@node MS-Windows Registry
+@appendixsubsec The MS-Windows System Registry
+@pindex addpm, MS-Windows installation program
+@cindex registry, setting environment variables and resources on MS-Windows
+
+On MS-Windows, the installation program @command{addpm.exe} adds values
+for @env{emacs_dir}, @env{EMACSLOADPATH}, @env{EMACSDATA},
+@env{EMACSPATH}, @env{EMACSDOC}, @env{SHELL} and @env{TERM} to the
+@file{HKEY_LOCAL_MACHINE} section of the system registry, under
+@file{/Software/GNU/Emacs}. It does this because there is no standard
+place to set environment variables across different versions of
+Windows. Running @command{addpm.exe} is no longer strictly
+necessary in recent versions of Emacs, but if you are upgrading from
+an older version, running @command{addpm.exe} ensures that you do not have
+older registry entries from a previous installation, which may not be
+compatible with the latest version of Emacs.
+
+When Emacs starts, as well as checking the environment, it also checks
+the System Registry for those variables and for @env{HOME}, @env{LANG}
+and @env{PRELOAD_WINSOCK}.
+
+To determine the value of those variables, Emacs goes through the
+following procedure. First, the environment is checked. If the
+variable is not found there, Emacs looks for registry keys by that
+name under @file{/Software/GNU/Emacs}; first in the
+@file{HKEY_CURRENT_USER} section of the registry, and if not found
+there, in the @file{HKEY_LOCAL_MACHINE} section. Finally, if Emacs
+still cannot determine the values, compiled-in defaults are used.
+
+In addition to the environment variables above, you can also add many
+of the settings which on X belong in the @file{.Xdefaults} file
+(@pxref{X Resources}) to the @file{/Software/GNU/Emacs} registry key.
+Settings you add to the @file{HKEY_LOCAL_MACHINE} section will affect
+all users of the machine. Settings you add to the
+@file{HKEY_CURRENT_USER} section will only affect you, and will
+override machine wide settings.
+
+@node Display X
+@appendixsec Specifying the Display Name
+@cindex display name (X Window System)
+@cindex @env{DISPLAY} environment variable
+
+ The environment variable @env{DISPLAY} tells all X clients, including
+Emacs, where to display their windows. Its value is set by default
+in ordinary circumstances, when you start an X server and run jobs
+locally. Occasionally you may need to specify the display yourself; for
+example, if you do a remote login and want to run a client program
+remotely, displaying on your local screen.
+
+ With Emacs, the main reason people change the default display is to
+let them log into another system, run Emacs on that system, but have the
+window displayed at their local terminal. You might need to log in
+to another system because the files you want to edit are there, or
+because the Emacs executable file you want to run is there.
+
+ The syntax of the @env{DISPLAY} environment variable is
+@samp{@var{host}:@var{display}.@var{screen}}, where @var{host} is the
+host name of the X Window System server machine, @var{display} is an
+arbitrarily-assigned number that distinguishes your server (X terminal)
+from other servers on the same machine, and @var{screen} is a
+rarely-used field that allows an X server to control multiple terminal
+screens. The period and the @var{screen} field are optional. If
+included, @var{screen} is usually zero.
+
+ For example, if your host is named @samp{glasperle} and your server is
+the first (or perhaps the only) server listed in the configuration, your
+@env{DISPLAY} is @samp{glasperle:0.0}.
+
+ You can specify the display name explicitly when you run Emacs, either
+by changing the @env{DISPLAY} variable, or with the option @samp{-d
+@var{display}} or @samp{--display=@var{display}}. Here is an example:
+
+@smallexample
+emacs --display=glasperle:0 &
+@end smallexample
+
+ You can inhibit the direct use of the window system and GUI with the
+@samp{-nw} option. It tells Emacs to display using ordinary ASCII on
+its controlling terminal. This is also an initial option.
+
+ Sometimes, security arrangements prevent a program on a remote system
+from displaying on your local system. In this case, trying to run Emacs
+produces messages like this:
+
+@smallexample
+Xlib: connection to "glasperle:0.0" refused by server
+@end smallexample
+
+@noindent
+You might be able to overcome this problem by using the @command{xhost}
+command on the local system to give permission for access from your
+remote machine.
+
+@node Font X
+@appendixsec Font Specification Options
+@cindex font name (X Window System)
+
+ By default, Emacs displays text in the font named @samp{9x15}, which
+makes each character nine pixels wide and fifteen pixels high. You can
+specify a different font on your command line through the option
+@samp{-fn @var{name}} (or @samp{--font}, which is an alias for
+@samp{-fn}).
+
+@table @samp
+@item -fn @var{name}
+@opindex -fn
+@itemx --font=@var{name}
+@opindex --font
+@cindex specify default font from the command line
+Use font @var{name} as the default font.
+@end table
+
+ Under X, each font has a long name which consists of eleven words or
+numbers, separated by dashes. Some fonts also have shorter
+nicknames---@samp{9x15} is such a nickname. You can use either kind of
+name. You can use wildcard patterns for the font name; then Emacs lets
+X choose one of the fonts that match the pattern. Here is an example,
+which happens to specify the font whose nickname is @samp{6x13}:
+
+@smallexample
+emacs -fn \
+ "-misc-fixed-medium-r-semicondensed--13-*-*-*-c-60-iso8859-1" &
+@end smallexample
+
+@noindent
+You can also specify the font in your @file{.Xdefaults} file:
+
+@smallexample
+emacs.font: -misc-fixed-medium-r-semicondensed--13-*-*-*-c-60-iso8859-1
+@end smallexample
+
+ A long font name has the following form:
+
+@smallexample
+-@var{maker}-@var{family}-@var{weight}-@var{slant}-@var{widthtype}-@var{style}@dots{}
+@dots{}-@var{pixels}-@var{height}-@var{horiz}-@var{vert}-@var{spacing}-@var{width}-@var{charset}
+@end smallexample
+
+@table @var
+@item maker
+This is the name of the font manufacturer.
+@item family
+This is the name of the font family---for example, @samp{courier}.
+@item weight
+This is normally @samp{bold}, @samp{medium} or @samp{light}. Other
+words may appear here in some font names.
+@item slant
+This is @samp{r} (roman), @samp{i} (italic), @samp{o} (oblique),
+@samp{ri} (reverse italic), or @samp{ot} (other).
+@item widthtype
+This is normally @samp{condensed}, @samp{extended}, @samp{semicondensed}
+or @samp{normal}. Other words may appear here in some font names.
+@item style
+This is an optional additional style name. Usually it is empty---most
+long font names have two hyphens in a row at this point.
+@item pixels
+This is the font height, in pixels.
+@item height
+This is the font height on the screen, measured in tenths of a printer's
+point---approximately 1/720 of an inch. In other words, it is the point
+size of the font, times ten. For a given vertical resolution,
+@var{height} and @var{pixels} are proportional; therefore, it is common
+to specify just one of them and use @samp{*} for the other.
+@item horiz
+This is the horizontal resolution, in pixels per inch, of the screen for
+which the font is intended.
+@item vert
+This is the vertical resolution, in pixels per inch, of the screen for
+which the font is intended. Normally the resolution of the fonts on
+your system is the right value for your screen; therefore, you normally
+specify @samp{*} for this and @var{horiz}.
+@item spacing
+This is @samp{m} (monospace), @samp{p} (proportional) or @samp{c}
+(character cell).
+@item width
+This is the average character width, in pixels, multiplied by ten.
+@item charset
+This is the character set that the font depicts.
+Normally you should use @samp{iso8859-1}.
+@end table
+
+@cindex listing system fonts
+ You will probably want to use a fixed-width default font---that is,
+a font in which all characters have the same width. Any font with
+@samp{m} or @samp{c} in the @var{spacing} field of the long name is a
+fixed-width font. Here's how to use the @command{xlsfonts} program to
+list all the fixed-width fonts available on your system:
+
+@example
+xlsfonts -fn '*x*' | egrep "^[0-9]+x[0-9]+"
+xlsfonts -fn '*-*-*-*-*-*-*-*-*-*-*-m*'
+xlsfonts -fn '*-*-*-*-*-*-*-*-*-*-*-c*'
+@end example
+
+@noindent
+To see what a particular font looks like, use the @command{xfd} command.
+For example:
+
+@example
+xfd -fn 6x13
+@end example
+
+@noindent
+displays the entire font @samp{6x13}.
+
+ While running Emacs, you can set the font of the current frame
+(@pxref{Frame Parameters}) or for a specific kind of text
+(@pxref{Faces}).
+
+@node Colors
+@appendixsec Window Color Options
+@cindex color of window
+@cindex text colors, from command line
+
+@findex list-colors-display
+@cindex available colors
+ On a color display, you can specify which color to use for various
+parts of the Emacs display. To find out what colors are available on
+your system, type @kbd{M-x list-colors-display}, or press
+@kbd{C-Mouse-2} and select @samp{Display Colors} from the pop-up menu.
+If you do not specify colors, on windowed displays the default for the
+background is white and the default for all other colors is black. On a
+monochrome display, the foreground is black, the background is white,
+and the border is gray if the display supports that. On terminals, the
+background is usually black and the foreground is white.
+
+ Here is a list of the command-line options for specifying colors:
+
+@table @samp
+@item -fg @var{color}
+@opindex -fg
+@itemx --foreground-color=@var{color}
+@opindex --foreground-color
+@cindex foreground color, command-line argument

+@item --color=@var{mode}
+@opindex --color
+@cindex standard colors on a character terminal
+For a character terminal only, specify the mode of color support. The
+parameter @var{mode} can be one of the following:
+@table @samp
+@item never
+@itemx no
+Don't use colors even if the terminal's capabilities specify color
+support.
+@item default
+@itemx auto
+Same as when @option{--color} is not used at all: Emacs detects at
+startup whether the terminal supports colors, and if it does, turns on
+colored display.
+@item always
+@itemx yes
+@itemx ansi8
+Turn on the color support unconditionally, and use color commands
+specified by the ANSI escape sequences for the 8 standard colors.
+@item @var{num}
+Use color mode for @var{num} colors. If @var{num} is -1, turn off
+color support (equivalent to @samp{never}); if it is 0, use the
+default color support for this terminal (equivalent to @samp{auto});
+otherwise use an appropriate standard mode for @var{num} colors. If
+there is no mode that supports @var{num} colors, Emacs acts as if
+@var{num} were 0, i.e.@: it uses the terminal's default color support
+mode.

+@cindex position and size of Emacs frame
+@cindex width and height of Emacs frame
+@cindex specifying fullscreen for Emacs frame
+
+ Here is a list of the command-line options for specifying size and
+position of the initial Emacs frame:
+
+@table @samp
+@item -g @var{width}x@var{height}@r{[@{}+-@r{@}}@var{xoffset}@r{@{}+-@r{@}}@var{yoffset}@r{]]}
+@opindex -g
+Specify the size @var{width} and @var{height} (measured in character
+columns and lines), and positions @var{xoffset} and @var{yoffset}
+(measured in pixels). This applies to all frames.
+
+@item --geometry=@var{width}x@var{height}@r{[@{}+-@r{@}}@var{xoffset}@r{@{}+-@r{@}}@var{yoffset}@r{]]}
+@opindex --geometry
+This is another way of writing the same thing.
+
+@item -fs
+@opindex -fs
+@itemx --fullscreen
+@opindex --fullscreen
+@cindex fullscreen, command-line argument
+Specify that width and height shall be the size of the screen.
+
+@item -fh
+@opindex -fh
+@itemx --fullheight
+@opindex --fullheight
+@cindex fullheight, command-line argument
+Specify that the height shall be the height of the screen.
+
+@item -fw
+@opindex -fw
+@itemx --fullwidth
+@opindex --fullwidth
+@cindex fullwidth, command-line argument
+Specify that the width shall be the width of the screen.
+@end table
+
+
+@noindent
+In the @samp{--geometry} option, @code{@r{@{}+-@r{@}}} means either a plus
+ sign or a minus sign. A plus
+sign before @var{xoffset} means it is the distance from the left side of
+the screen; a minus sign means it counts from the right side. A plus
+sign before @var{yoffset} means it is the distance from the top of the
+screen, and a minus sign there indicates the distance from the bottom.
+The values @var{xoffset} and @var{yoffset} may themselves be positive or
+negative, but that doesn't change their meaning, only their direction.
+
+ Emacs uses the same units as @command{xterm} does to interpret the geometry.
+The @var{width} and @var{height} are measured in characters, so a large font
+creates a larger frame than a small font. (If you specify a proportional
+font, Emacs uses its maximum bounds width as the width unit.) The
+@var{xoffset} and @var{yoffset} are measured in pixels.
+
+ You do not have to specify all of the fields in the geometry
+specification. If you omit both @var{xoffset} and @var{yoffset}, the
+window manager decides where to put the Emacs frame, possibly by
+letting you place it with the mouse. For example, @samp{164x55}
+specifies a window 164 columns wide, enough for two ordinary width
+windows side by side, and 55 lines tall.
+
+ The default width for Emacs is 80 characters and the default height is
+40 lines. You can omit either the width or the height or both. If
+you start the geometry with an integer, Emacs interprets it as the
+width. If you start with an @samp{x} followed by an integer, Emacs
+interprets it as the height. Thus, @samp{81} specifies just the width;
+@samp{x45} specifies just the height.
+
+ If you start with @samp{+} or @samp{-}, that introduces an offset,
+which means both sizes are omitted. Thus, @samp{-3} specifies the
+@var{xoffset} only. (If you give just one offset, it is always
+@var{xoffset}.) @samp{+3-3} specifies both the @var{xoffset} and the
+@var{yoffset}, placing the frame near the bottom left of the screen.
+
+ You can specify a default for any or all of the fields in
+@file{.Xdefaults} file, and then override selected fields with a
+@samp{--geometry} option.
+
+ Since the mode line and the echo area occupy the last 2 lines of the
+frame, the height of the initial text window is 2 less than the height
+specified in your geometry. In non-X-toolkit versions of Emacs, the
+menu bar also takes one line of the specified number. But in the X
+toolkit version, the menu bar is additional and does not count against
+the specified height. The tool bar, if present, is also additional.
+
+ Enabling or disabling the menu bar or tool bar alters the amount of
+space available for ordinary text. Therefore, if Emacs starts up with
+a tool bar (which is the default), and handles the geometry
+specification assuming there is a tool bar, and then your
+@file{~/.emacs} file disables the tool bar, you will end up with a
+frame geometry different from what you asked for. To get the intended
+size with no tool bar, use an X resource to specify ``no tool bar''
+(@pxref{Table of Resources});then Emacs will already know there's no
+tool bar when it processes the specified geometry.
+
+ When using one of @samp{--fullscreen}, @samp{--fullwidth} or
+@samp{--fullheight} there may be some space around the frame
+anyway. That is because Emacs rounds the sizes so they are an
+even number of character heights and widths.
+
+ Some window managers have options that can make them ignore both
+program-specified and user-specified positions (sawfish is one).
+If these are set, Emacs fails to position the window correctly.
+
+@node Borders X
+@appendixsec Internal and External Borders
+@cindex borders (X Window System)
+
+ An Emacs frame has an internal border and an external border. The
+internal border is an extra strip of the background color around the
+text portion of the frame. Emacs itself draws the internal border.
+The external border is added by the window manager outside the frame;
+depending on the window manager you use, it may contain various boxes
+you can click on to move or iconify the window.
+
+@table @samp
+@item -ib @var{width}
+@opindex -ib
+@itemx --internal-border=@var{width}
+@opindex --internal-border
+@cindex border width, command-line argument
+Specify @var{width} as the width of the internal border, in pixels.
+
+@item -bw @var{width}
+@opindex -bw
+@itemx --border-width=@var{width}
+@opindex --border-width
+Specify @var{width} as the width of the main border, in pixels.
+@end table
+
+ When you specify the size of the frame, that does not count the
+borders. The frame's position is measured from the outside edge of the
+external border.
+
+ Use the @samp{-ib @var{n}} option to specify an internal border
+@var{n} pixels wide. The default is 1. Use @samp{-bw @var{n}} to
+specify the width of the external border (though the window manager may
+not pay attention to what you specify). The default width of the
+external border is 2.
+
+@node Title X
+@appendixsec Frame Titles
+
+ An Emacs frame may or may not have a specified title. The frame
+title, if specified, appears in window decorations and icons as the
+name of the frame. If an Emacs frame has no specified title, the
+default title has the form @samp{@var{invocation-name}@@@var{machine}}
+(if there is only one frame) or the selected window's buffer name (if
+there is more than one frame).
+
+ You can specify a title for the initial Emacs frame with a command
+line option:
+
+@table @samp
+@item -title @var{title}
+@opindex --title
+@itemx --title=@var{title}
+@itemx -T @var{title}
+@opindex -T
+@cindex frame title, command-line argument
+Specify @var{title} as the title for the initial Emacs frame.
+@end table
+
+ The @samp{--name} option (@pxref{Resources}) also specifies the title
+for the initial Emacs frame.
+
+@node Icons X
+@appendixsec Icons
+@cindex icons (X Window System)
+
+ Most window managers allow the user to ``iconify'' a frame, removing
+it from sight, and leaving a small, distinctive ``icon'' window in its
+place. Clicking on the icon window makes the frame itself appear again.
+If you have many clients running at once, you can avoid cluttering up
+the screen by iconifying most of the clients.
+
+@table @samp
+@item -i
+@opindex -i
+@itemx --icon-type
+@opindex --icon-type
+@cindex Emacs icon, a gnu
+Use a picture of a gnu as the Emacs icon.
+
+@item -iconic
+@opindex --iconic
+@itemx --iconic
+@cindex start iconified, command-line argument
+Start Emacs in iconified state.
+@end table
+
+ The @samp{-i} or @samp{--icon-type} option tells Emacs to use an icon
+window containing a picture of the GNU gnu. If omitted, Emacs lets the
+window manager choose what sort of icon to use---usually just a small
+rectangle containing the frame's title.
+
+ The @samp{-iconic} option tells Emacs to begin running as an icon,
+rather than showing a frame right away. In this situation, the icon
+is the only indication that Emacs has started; the text frame doesn't
+appear until you deiconify it.
