address@hidden Glossary
+
address@hidden @asis
address@hidden Abbrev
+An abbrev is a text string which expands into a different text string
+when present in the buffer.  For example, you might define a few letters
+as an abbrev for a long phrase that you want to insert frequently.
address@hidden
+
address@hidden Aborting
+Aborting means getting out of a recursive edit (q.v.@:).  The
+commands @kbd{C-]} and @kbd{M-x top-level} are used for this.
address@hidden
+
address@hidden Alt
+Alt is the name of a modifier bit which a keyboard input character may
+have.  To make a character Alt, type it while holding down the @key{ALT}
+key.  Such characters are given names that start with @kbd{Alt-}
+(usually written @kbd{A-} for short).  (Note that many terminals have a
+key labeled @key{ALT} which is really a @key{META} key.)  @xref{User
+Input, Alt}.
+
address@hidden Argument
+See `numeric argument.'
+
address@hidden @acronym{ASCII} character
+An @acronym{ASCII} character is either an @acronym{ASCII} control character or 
an @acronym{ASCII}
+printing character.  @xref{User Input}.
+
address@hidden @acronym{ASCII} control character
+An @acronym{ASCII} control character is the Control version of an upper-case
+letter, or the Control version of one of the characters @samp{@@[\]^_?}.
+
address@hidden @acronym{ASCII} printing character
address@hidden printing characters include letters, digits, space, and these
+punctuation characters: @samp{!@@#$%^& *()_-+=|\~` @address@hidden:;"' <>,.?/}.
+
address@hidden Auto Fill Mode
+Auto Fill mode is a minor mode in which text that you insert is
+automatically broken into lines of a given maximum width.
address@hidden
+
address@hidden Auto Saving
+Auto saving is the practice of saving the contents of an Emacs buffer in
+a specially-named file, so that the information will not be lost if the
+buffer is lost due to a system error or user error.  @xref{Auto Save}.
+
address@hidden Autoloading
+Emacs automatically loads Lisp libraries when a Lisp program requests a
+function or a variable from those libraries.  This is called
+`autoloading'.  @xref{Lisp Libraries}.
+
address@hidden Backtrace
+A backtrace is a trace of a series of function calls showing how a
+program arrived to a certain point.  It is used mainly for finding and
+correcting bugs (q.v.@:).  Emacs can display a backtrace when it signals
+an error or when you type @kbd{C-g} (see `quitting').  @xref{Checklist}.
+
address@hidden Backup File
+A backup file records the contents that a file had before the current
+editing session.  Emacs makes backup files automatically to help you
+track down or cancel changes you later regret making.  @xref{Backup}.
+
address@hidden Balancing Parentheses
+Emacs can balance parentheses (or other matching delimiters) either
+manually or automatically.  You do manual balancing with the commands
+to move over parenthetical groupings (@pxref{Moving by Parens}).
+Automatic balancing works by blinking or highlighting the delimiter
+that matches the one you just inserted (@pxref{Matching,,Matching
+Parens}).
+
address@hidden Balanced Expressions
+A balanced expression is a syntactically recognizable expression, such
+as a symbol, number, string constant, block, or parenthesized expression
+in C.  @xref{Expressions,Balanced Expressions}.
+
address@hidden Balloon Help
+See `tooltips.'
+
address@hidden Base Buffer
+A base buffer is a buffer whose text is shared by an indirect buffer
+(q.v.@:).
+
address@hidden Bind
+To bind a key sequence means to give it a binding (q.v.@:).
address@hidden
+
address@hidden Binding
+A key sequence gets its meaning in Emacs by having a binding, which is a
+command (q.v.@:), a Lisp function that is run when the user types that
+sequence.  @xref{Commands,Binding}.  Customization often involves
+rebinding a character to a different command function.  The bindings of
+all key sequences are recorded in the keymaps (q.v.@:).  @xref{Keymaps}.
+
address@hidden Blank Lines
+Blank lines are lines that contain only whitespace.  Emacs has several
+commands for operating on the blank lines in the buffer.
+
address@hidden Bookmark
+Bookmarks are akin to registers (q.v.@:) in that they record positions
+in buffers to which you can return later.  Unlike registers, bookmarks
+persist between Emacs sessions.
+
address@hidden Border
+A border is a thin space along the edge of the frame, used just for
+spacing, not for displaying anything.  An Emacs frame has an ordinary
+external border, outside of everything including the menu bar, plus an
+internal border that surrounds the text windows and their scroll bars
+and separates them from the menu bar and tool bar.  You can customize
+both borders with options and resources (@pxref{Borders X}).  Borders
+are not the same as fringes (q.v.@:).
+
address@hidden Buffer
+The buffer is the basic editing unit; one buffer corresponds to one text
+being edited.  You can have several buffers, but at any time you are
+editing only one, the `current buffer,' though several can be visible
+when you are using multiple windows (q.v.@:).  Most buffers are visiting
+(q.v.@:) some file.  @xref{Buffers}.
+
address@hidden Buffer Selection History
+Emacs keeps a buffer selection history which records how recently each
+Emacs buffer has been selected.  This is used for choosing a buffer to
+select.  @xref{Buffers}.
+
address@hidden Bug
+A bug is an incorrect or unreasonable behavior of a program, or
+inaccurate or confusing documentation.  Emacs developers treat bug
+reports, both in Emacs code and its documentation, very seriously and
+ask you to report any bugs you find.  @xref{Bugs}.
+
address@hidden Button Down Event
+A button down event is the kind of input event generated right away when
+you press down on a mouse button.  @xref{Mouse Buttons}.
+
address@hidden By Default
+See `default.'
+
address@hidden Byte Compilation
+See `compilation.'
+
address@hidden @kbd{C-}
address@hidden in the name of a character is an abbreviation for Control.
address@hidden Input,C-}.
+
address@hidden @kbd{C-M-}
address@hidden in the name of a character is an abbreviation for
+Control-Meta.  @xref{User Input,C-M-}.
+
address@hidden Case Conversion
+Case conversion means changing text from upper case to lower case or
+vice versa.  @xref{Case}, for the commands for case conversion.
+
address@hidden Character
+Characters form the contents of an Emacs buffer; see @ref{Text
+Characters}.  Also, key sequences (q.v.@:) are usually made up of
+characters (though they may include other input events as well).
address@hidden Input}.
+
address@hidden Character Set
+Emacs supports a number of character sets, each of which represents a
+particular alphabet or script.  @xref{International}.
+
address@hidden Character Terminal
+See `text-only terminal.'
+
address@hidden Click Event
+A click event is the kind of input event generated when you press a
+mouse button and release it without moving the mouse.  @xref{Mouse Buttons}.
+
address@hidden Clipboard
+A clipboard is a buffer provided by the window system for transferring
+text between applications.  On the X Window system, the clipboard is
+provided in addition to the primary selection (q.v.@:); on MS-Windows and Mac,
+the clipboard is used @emph{instead} of the primary selection.
address@hidden
+
address@hidden Coding System
+A coding system is an encoding for representing text characters in a
+file or in a stream of information.  Emacs has the ability to convert
+text to or from a variety of coding systems when reading or writing it.
address@hidden Systems}.
+
address@hidden Command
+A command is a Lisp function specially defined to be able to serve as a
+key binding in Emacs.  When you type a key sequence (q.v.@:), its
+binding (q.v.@:) is looked up in the relevant keymaps (q.v.@:) to find
+the command to run.  @xref{Commands}.
+
address@hidden Command History
+See `minibuffer history.'
+
address@hidden Command Name
+A command name is the name of a Lisp symbol which is a command
+(@pxref{Commands}).  You can invoke any command by its name using
address@hidden (@pxref{M-x,M-x,Running Commands by Name}).
+
address@hidden Comment
+A comment is text in a program which is intended only for humans reading
+the program, and which is marked specially so that it will be ignored
+when the program is loaded or compiled.  Emacs offers special commands
+for creating, aligning and killing comments.  @xref{Comments}.
+
address@hidden Common Lisp
+Common Lisp is a dialect of Lisp (q.v.@:) much larger and more powerful
+than Emacs Lisp.  Emacs provides a subset of Common Lisp in the CL
+package.  @xref{Top, Common Lisp, Overview, cl, Common Lisp Extensions}.
+
address@hidden Compilation
+Compilation is the process of creating an executable program from source
+code.  Emacs has commands for compiling files of Emacs Lisp code
+(@pxref{Byte Compilation,,, elisp, the Emacs Lisp
+Reference Manual}) and programs in C and other languages
+(@pxref{Compilation}).
+
address@hidden Complete Key
+A complete key is a key sequence which fully specifies one action to be
+performed by Emacs.  For example, @kbd{X} and @kbd{C-f} and @kbd{C-x m}
+are complete keys.  Complete keys derive their meanings from being bound
+(q.v.@:) to commands (q.v.@:).  Thus, @kbd{X} is conventionally bound to
+a command to insert @samp{X} in the buffer; @kbd{C-x m} is
+conventionally bound to a command to begin composing a mail message.
address@hidden
+
address@hidden Completion
+Completion is what Emacs does when it automatically fills out an
+abbreviation for a name into the entire name.  Completion is done for
+minibuffer (q.v.@:) arguments when the set of possible valid inputs
+is known; for example, on command names, buffer names, and
+file names.  Completion occurs when @key{TAB}, @key{SPC} or @key{RET}
+is typed.  @address@hidden
+
address@hidden Continuation Line
+When a line of text is longer than the width of the window, it
+takes up more than one screen line when displayed.  We say that the
+text line is continued, and all screen lines used for it after the
+first are called continuation lines.  @xref{Continuation Lines}.
+A related Emacs feature is `filling' (q.v.@:).
+
address@hidden Control Character
+A control character is a character that you type by holding down the
address@hidden key.  Some control characters also have their own keys, so
+that you can type them without using @key{CTRL}.  For example,
address@hidden, @key{TAB}, @key{ESC} and @key{DEL} are all control
+characters.  @xref{User Input}.
+
address@hidden Copyleft
+A copyleft is a notice giving the public legal permission to
+redistribute and modify a program or other work of art, but requiring
+modified versions to carry similar permission.  Copyright is normally
+used to keep users divided and helpless; with copyleft we turn that
+around to empower users and encourage them to cooperate.
+
+The particular form of copyleft used by the GNU project is called the
+GNU General Public License.  @xref{Copying}.
+
address@hidden @key{CTRL}
+The @key{CTRL} or ``control'' key is what you hold down
+in order to enter a control character (q.v.).
+
address@hidden Current Buffer
+The current buffer in Emacs is the Emacs buffer on which most editing
+commands operate.  You can select any Emacs buffer as the current one.
address@hidden
+
address@hidden Current Line
+The current line is the line that point is on (@pxref{Point}).
+
address@hidden Current Paragraph
+The current paragraph is the paragraph that point is in.  If point is
+between two paragraphs, the current paragraph is the one that follows
+point.  @xref{Paragraphs}.
+
address@hidden Current Defun
+The current defun is the defun (q.v.@:) that point is in.  If point is
+between defuns, the current defun is the one that follows point.
address@hidden
+
address@hidden Cursor
+The cursor is the rectangle on the screen which indicates the position
+called point (q.v.@:) at which insertion and deletion takes place.
+The cursor is on or under the character that follows point.  Often
+people speak of `the cursor' when, strictly speaking, they mean
+`point.'  @xref{Point,Cursor}.
+
address@hidden Customization
+Customization is making minor changes in the way Emacs works.  It is
+often done by setting variables (@pxref{Variables}) or faces
+(@pxref{Face Customization}), or by rebinding key sequences
+(@pxref{Keymaps}).
+
address@hidden cut and paste
address@hidden Cut and Paste
+See `killing' and `yanking.'
+
address@hidden Default Argument
+The default for an argument is the value that will be assumed if you
+do not specify one.  When the minibuffer is used to read an argument,
+the default argument is used if you just type @key{RET}.
address@hidden
+
address@hidden Default
+A default is the value that is used for a certain purpose if and when
+you do not specify a value to use.
+
address@hidden Default Directory
+When you specify a file name that does not start with @samp{/} or @samp{~},
+it is interpreted relative to the current buffer's default directory.
+(On MS-Windows and MS-DOS, file names which start with a drive letter
address@hidden@var{x}:} are treated as absolute, not relative.)
address@hidden File,Default Directory}.
+
address@hidden Defun
+A defun is a major definition at the top level in a program.  The name
+`defun' comes from Lisp, where most such definitions use the construct
address@hidden  @xref{Defuns}.
+
address@hidden @key{DEL}
address@hidden is a character that runs the command to delete one character
+of text before the cursor.  It is typically either the @key{DELETE}
+key or the @key{BACKSPACE} key, whichever one is easy to type.
address@hidden,DEL}.
+
address@hidden Deletion
+Deletion means erasing text without copying it into the kill ring
+(q.v.@:).  The alternative is killing (q.v.@:).  @xref{Killing,Deletion}.
+
address@hidden Deletion of Files
+Deleting a file means erasing it from the file system.
address@hidden File Ops,Misc File Ops,Miscellaneous File Operations}.
+
address@hidden Deletion of Messages
+Deleting a message means flagging it to be eliminated from your mail
+file.  Until you expunge (q.v.@:) the Rmail file, you can still undelete
+the messages you have deleted.  @xref{Rmail Deletion}.
+
address@hidden Deletion of Windows
+Deleting a window means eliminating it from the screen.  Other windows
+expand to use up the space.  The deleted window can never come back,
+but no actual text is thereby lost.  @xref{Windows}.
+
address@hidden Directory
+File directories are named collections in the file system, within which
+you can place individual files or subdirectories.  @xref{Directories}.
+
address@hidden Dired
+Dired is the Emacs facility that displays the contents of a file
+directory and allows you to ``edit the directory,'' performing
+operations on the files in the directory.  @xref{Dired}.
+
address@hidden Disabled Command
+A disabled command is one that you may not run without special
+confirmation.  The usual reason for disabling a command is that it is
+confusing for beginning users.  @xref{Disabling}.
+
address@hidden Down Event
+Short for `button down event' (q.v.@:).
+
address@hidden Drag Event
+A drag event is the kind of input event generated when you press a mouse
+button, move the mouse, and then release the button.  @xref{Mouse
+Buttons}.
+
address@hidden Dribble File
+A dribble file is a file into which Emacs writes all the characters that
+you type on the keyboard.  Dribble files are used to make a record
+for debugging Emacs bugs.  Emacs does not make a dribble file unless you
+tell it to.  @xref{Bugs}.
+
address@hidden Echo Area
+The echo area is the bottom line of the screen, used for echoing the
+arguments to commands, for asking questions, and showing brief messages
+(including error messages).  The messages are stored in the buffer
address@hidden so you can review them later.  @xref{Echo Area}.
+
address@hidden Echoing
+Echoing is acknowledging the receipt of input events by displaying
+them (in the echo area).  Emacs never echoes single-character key
+sequences; longer key sequences echo only if you pause while typing
+them.
+
address@hidden Electric
+We say that a character is electric if it is normally self-inserting
+(q.v.@:), but the current major mode (q.v.@:) redefines it to do something
+else as well.  For example, some programming language major modes define
+particular delimiter characters to reindent the line or insert one or
+more newlines in addition to self-insertion.
+
address@hidden End Of Line
+End of line is a character or a sequence of characters that indicate
+the end of a text line.  On GNU and Unix systems, this is a newline
+(q.v.@:), but other systems have other conventions.  @xref{Coding
+Systems,end-of-line}.  Emacs can recognize several end-of-line
+conventions in files and convert between them.
+
address@hidden Environment Variable
+An environment variable is one of a collection of variables stored by
+the operating system, each one having a name and a value.  Emacs can
+access environment variables set by its parent shell, and it can set
+variables in the environment it passes to programs it invokes.
address@hidden
+
address@hidden EOL
+See `end of line.'
+
address@hidden Error
+An error occurs when an Emacs command cannot execute in the current
+circumstances.  When an error occurs, execution of the command stops
+(unless the command has been programmed to do otherwise) and Emacs
+reports the error by displaying an error message (q.v.@:).  Type-ahead
+is discarded.  Then Emacs is ready to read another editing command.
+
address@hidden Error Message
+An error message is a single line of output displayed by Emacs when the
+user asks for something impossible to do (such as, killing text
+forward when point is at the end of the buffer).  They appear in the
+echo area, accompanied by a beep.
+
address@hidden @key{ESC}
address@hidden is a character used as a prefix for typing Meta characters on
+keyboards lacking a @key{META} key.  Unlike the @key{META} key (which,
+like the @key{SHIFT} key, is held down while another character is
+typed), you press the @key{ESC} key as you would press a letter key, and
+it applies to the next character you type.
+
address@hidden Expression
+See `balanced expression.'
+
address@hidden Expunging
+Expunging an Rmail file or Dired buffer or a Gnus newsgroup buffer is an
+operation that truly discards the messages or files you have previously
+flagged for deletion.
+
address@hidden Face
+A face is a style of displaying characters.  It specifies attributes
+such as font family and size, foreground and background colors,
+underline and strike-through, background stipple, etc.  Emacs provides
+features to associate specific faces with portions of buffer text, in
+order to display that text as specified by the face attributes.
address@hidden
+
address@hidden File Locking
+Emacs uses file locking to notice when two different users
+start to edit one file at the same time.  @xref{Interlocking}.
+
address@hidden File Name
+A file name is a name that refers to a file.  File names may be relative
+or absolute; the meaning of a relative file name depends on the current
+directory, but an absolute file name refers to the same file regardless
+of which directory is current.  On GNU and Unix systems, an absolute
+file name starts with a slash (the root directory) or with @samp{~/} or
address@hidden@var{user}/} (a home directory).  On MS-Windows/MS-DOS, an
+absolute file name can also start with a drive letter and a colon
address@hidden@var{d}:}.
+
+Some people use the term ``pathname'' for file names, but we do not;
+we use the word ``path'' only in the term ``search path'' (q.v.@:).
+
address@hidden File-Name Component
+A file-name component names a file directly within a particular
+directory.  On GNU and Unix systems, a file name is a sequence of
+file-name components, separated by slashes.  For example, @file{foo/bar}
+is a file name containing two components, @samp{foo} and @samp{bar}; it
+refers to the file named @samp{bar} in the directory named @samp{foo} in
+the current directory.  MS-DOS/MS-Windows file names can also use
+backslashes to separate components, as in @file{foo\bar}.
+
address@hidden Fill Prefix
+The fill prefix is a string that should be expected at the beginning
+of each line when filling is done.  It is not regarded as part of the
+text to be filled.  @xref{Filling}.
+
address@hidden Filling
+Filling text means shifting text between consecutive lines so that all
+the lines are approximately the same length.  @xref{Filling}.  Some
+other editors call this feature `line wrapping.'
+
address@hidden Font Lock
+Font Lock is a mode that highlights parts of buffer text according to
+its syntax.  @xref{Font Lock}.
+
address@hidden Fontset
+A fontset is a named collection of fonts.  A fontset specification lists
+character sets and which font to use to display each of them.  Fontsets
+make it easy to change several fonts at once by specifying the name of a
+fontset, rather than changing each font separately.  @xref{Fontsets}.
+
address@hidden Formatted Text
+Formatted text is text that displays with formatting information while
+you edit.  Formatting information includes fonts, colors, and specified
+margins.  @xref{Formatted Text}.
+
address@hidden Formfeed Character
+See `page.'
+
address@hidden Frame
+A frame is a rectangular cluster of Emacs windows.  Emacs starts out
+with one frame, but you can create more.  You can subdivide each frame
+into Emacs windows (q.v.@:).  When you are using a window system
+(q.v.@:), all the frames can be visible at the same time.
address@hidden  Some other editors use the term ``window'' for this,
+but in Emacs a window means something else.
+
address@hidden Fringe
+On a graphical display (q.v.@:), there's a narrow portion of the
+frame (q.v.@:) between the text area and the window's border.  Emacs
+displays the fringe using a special face (q.v.@:) called
address@hidden  @xref{Faces,fringe}.
+
address@hidden FTP
+FTP is an acronym for File Transfer Protocol.  Emacs uses an FTP client
+program to provide access to remote files (q.v.@:).
+
address@hidden Function Key
+A function key is a key on the keyboard that sends input but does not
+correspond to any character.  @xref{Function Keys}.
+
address@hidden Global
+Global means ``independent of the current environment; in effect
+throughout Emacs.''  It is the opposite of local (q.v.@:).  Particular
+examples of the use of `global' appear below.
+
address@hidden Global Abbrev
+A global definition of an abbrev (q.v.@:) is effective in all major
+modes that do not have local (q.v.@:) definitions for the same abbrev.
address@hidden
+
address@hidden Global Keymap
+The global keymap (q.v.@:) contains key bindings that are in effect
+except when overridden by local key bindings in a major mode's local
+keymap (q.v.@:).  @xref{Keymaps}.
+
address@hidden Global Mark Ring
+The global mark ring records the series of buffers you have recently
+set a mark (q.v.@:) in.  In many cases you can use this to backtrack
+through buffers you have been editing in, or in which you have found
+tags (see `tags table').  @xref{Global Mark Ring}.
+
address@hidden Global Substitution
+Global substitution means replacing each occurrence of one string by
+another string throughout a large amount of text.  @xref{Replace}.
+
address@hidden Global Variable
+The global value of a variable (q.v.@:) takes effect in all buffers
+that do not have their own local (q.v.@:) values for the variable.
address@hidden
+
address@hidden Graphic Character
+Graphic characters are those assigned pictorial images rather than
+just names.  All the non-Meta (q.v.@:) characters except for the
+Control (q.v.@:) characters are graphic characters.  These include
+letters, digits, punctuation, and spaces; they do not include
address@hidden or @key{ESC}.  In Emacs, typing a graphic character inserts
+that character (in ordinary editing modes).  @xref{Inserting Text}.
+
address@hidden Graphical Display
+A graphical display is one that can display images and multiple fonts.
+Usually it also has a window system (q.v.@:).
+
address@hidden Highlighting
+Highlighting text means displaying it with a different foreground and/or
+background color to make it stand out from the rest of the text in the
+buffer.
+
+Emacs uses highlighting in several ways.  When you mark a region with
+the mouse, the region is always highlighted.  Optionally Emacs can
+also highlight the region whenever it is active (@pxref{Transient
+Mark}).  Incremental search also highlights matches (@pxref{Incremental
+Search}).  See also `font lock'.
+
address@hidden Hardcopy
+Hardcopy means printed output.  Emacs has commands for making printed
+listings of text in Emacs buffers.  @xref{Printing}.
+
address@hidden @key{HELP}
address@hidden is the Emacs name for @kbd{C-h} or @key{F1}.  You can type
address@hidden at any time to ask what options you have, or to ask what any
+command does.  @xref{Help}.
+
address@hidden Help Echo
+Help echo is a short message displayed in the echo area when the mouse
+pointer is located on portions of display that require some
+explanations.  Emacs displays help echo for menu items, parts of the
+mode line, tool-bar buttons, etc.  On graphics displays, the messages
+can be displayed as tooltips (q.v.@:).  @xref{Tooltips}.
+
address@hidden Hook
+A hook is a list of functions to be called on specific occasions, such
+as saving a buffer in a file, major mode activation, etc.  By
+customizing the various hooks, you can modify Emacs's behavior without
+changing any of its code.  @xref{Hooks}.
+
address@hidden Hyper
+Hyper is the name of a modifier bit which a keyboard input character may
+have.  To make a character Hyper, type it while holding down the
address@hidden key.  Such characters are given names that start with
address@hidden (usually written @kbd{H-} for short).  @xref{User Input,
+Hyper}.
+
address@hidden Iff
+``Iff'' means ``if and only if.''  This terminology comes from
+mathematics.  Try to avoid using this term in documentation, since
+many are unfamiliar with it and mistake it for a typo.
+
address@hidden Inbox
+An inbox is a file in which mail is delivered by the operating system.
+Rmail transfers mail from inboxes to Rmail files (q.v.@:) in which the
+mail is then stored permanently or until explicitly deleted.
address@hidden Inbox}.
+
address@hidden Incremental Search
+Emacs provides an incremental search facility, whereby Emacs searches
+for the string as you type it.  @xref{Incremental Search}.
+
address@hidden Indentation
+Indentation means blank space at the beginning of a line.  Most
+programming languages have conventions for using indentation to
+illuminate the structure of the program, and Emacs has special
+commands to adjust indentation.
address@hidden
+
address@hidden Indirect Buffer
+An indirect buffer is a buffer that shares the text of another buffer,
+called its base buffer (q.v.@:).  @xref{Indirect Buffers}.
+
address@hidden Info
+Info is the hypertext format used by the GNU project for writing
+documentation.
+
address@hidden Input Event
+An input event represents, within Emacs, one action taken by the user on
+the terminal.  Input events include typing characters, typing function
+keys, pressing or releasing mouse buttons, and switching between Emacs
+frames.  @xref{User Input}.

address@hidden Keyboard Macro
+Keyboard macros are a way of defining new Emacs commands from
+sequences of existing ones, with no need to write a Lisp program.
address@hidden Macros}.
+
address@hidden keyboard shortcuts
address@hidden Keyboard Shortcut
+A keyboard shortcut is a key sequence (q.v.@:) which invokes a
+command.  What some programs call ``assigning a keyboard shortcut,''
+Emacs calls ``binding a key sequence.''  See `binding.'
+
address@hidden Key Sequence
+A key sequence (key, for short) is a sequence of input events (q.v.@:)
+that are meaningful as a single unit.  If the key sequence is enough to
+specify one action, it is a complete key (q.v.@:); if it is not enough,
+it is a prefix key (q.v.@:).  @xref{Keys}.
+
address@hidden Keymap
+The keymap is the data structure that records the bindings (q.v.@:) of
+key sequences to the commands that they run.  For example, the global
+keymap binds the character @kbd{C-n} to the command function
address@hidden  @xref{Keymaps}.
+
address@hidden Keyboard Translation Table
+The keyboard translation table is an array that translates the character
+codes that come from the terminal into the character codes that make up
+key sequences.
+
address@hidden Kill Ring
+The kill ring is where all text you have killed recently is saved.
+You can reinsert any of the killed text still in the ring; this is
+called yanking (q.v.@:).  @xref{Yanking}.
+
address@hidden Killing
+Killing means erasing text and saving it on the kill ring so it can be
+yanked (q.v.@:) later.  Some other systems call this ``cutting.''
+Most Emacs commands that erase text perform killing, as opposed to
+deletion (q.v.@:).  @xref{Killing}.
+
address@hidden Killing a Job
+Killing a job (such as, an invocation of Emacs) means making it cease
+to exist.  Any data within it, if not saved in a file, is lost.
address@hidden
+
address@hidden Language Environment
+Your choice of language environment specifies defaults for the input
+method (q.v.@:) and coding system (q.v.@:).  @xref{Language
+Environments}.  These defaults are relevant if you edit address@hidden text
+(@pxref{International}).
+
address@hidden Line Wrapping
+See `filling.'
+
address@hidden Lisp
+Lisp is a programming language.  Most of Emacs is written in a dialect
+of Lisp, called Emacs Lisp, that is extended with special features which
+make it especially suitable for text editing tasks.
+
address@hidden List
+A list is, approximately, a text string beginning with an open
+parenthesis and ending with the matching close parenthesis.  In C mode
+and other non-Lisp modes, groupings surrounded by other kinds of matched
+delimiters appropriate to the language, such as braces, are also
+considered lists.  Emacs has special commands for many operations on
+lists.  @xref{Moving by Parens}.
+
address@hidden Local
+Local means ``in effect only in a particular context''; the relevant
+kind of context is a particular function execution, a particular
+buffer, or a particular major mode.  It is the opposite of `global'
+(q.v.@:).  Specific uses of `local' in Emacs terminology appear below.
+
address@hidden Local Abbrev
+A local abbrev definition is effective only if a particular major mode
+is selected.  In that major mode, it overrides any global definition
+for the same abbrev.  @xref{Abbrevs}.
+
address@hidden Local Keymap
+A local keymap is used in a particular major mode; the key bindings
+(q.v.@:) in the current local keymap override global bindings of the
+same key sequences.  @xref{Keymaps}.
+
address@hidden Local Variable
+A local value of a variable (q.v.@:) applies to only one buffer.
address@hidden

address@hidden @kbd{M-}
address@hidden in the name of a character is an abbreviation for @key{META},
+one of the modifier keys that can accompany any character.
address@hidden Input,M-}.
+
address@hidden @kbd{M-C-}
address@hidden in the name of a character is an abbreviation for
+Control-Meta; it means the same thing as @kbd{C-M-}.  If your
+terminal lacks a real @key{META} key, you type a Control-Meta character by
+typing @key{ESC} and then typing the corresponding Control character.
address@hidden Input,C-M-}.
+
address@hidden @kbd{M-x}
address@hidden is the key sequence which is used to call an Emacs command by
+name.  This is how you run commands that are not bound to key sequences.
address@hidden,M-x,Running Commands by Name}.
+
address@hidden Mail
+Mail means messages sent from one user to another through the computer
+system, to be read at the recipient's convenience.  Emacs has commands for
+composing and sending mail, and for reading and editing the mail you have
+received.  @xref{Sending Mail}.  @xref{Rmail}, for how to read mail.
+
address@hidden Mail Composition Method
+A mail composition method is a program runnable within Emacs for editing
+and sending a mail message.  Emacs lets you select from several
+alternative mail composition methods.  @xref{Mail Methods}.
+
address@hidden Major Mode
+The Emacs major modes are a mutually exclusive set of options, each of
+which configures Emacs for editing a certain sort of text.  Ideally,
+each programming language has its own major mode.  @xref{Major Modes}.
+
address@hidden Margin
+The space between the usable part of a window (including the
+fringe) and the window edge.
+
address@hidden Mark
+The mark points to a position in the text.  It specifies one end of the
+region (q.v.@:), point being the other end.  Many commands operate on
+all the text from point to the mark.  Each buffer has its own mark.
address@hidden
+
address@hidden Mark Ring
+The mark ring is used to hold several recent previous locations of the
+mark, just in case you want to move back to them.  Each buffer has its
+own mark ring; in addition, there is a single global mark ring (q.v.@:).
address@hidden Ring}.
+
address@hidden Menu Bar
+The menu bar is the line at the top of an Emacs frame.  It contains
+words you can click on with the mouse to bring up menus, or you can use
+a keyboard interface to navigate it.  @xref{Menu Bars}.
+
address@hidden Message
+See `mail.'
+
address@hidden Meta
+Meta is the name of a modifier bit which you can use in a command
+character.  To enter a meta character, you hold down the @key{META}
+key while typing the character.  We refer to such characters with
+names that start with @kbd{Meta-} (usually written @kbd{M-} for
+short).  For example, @kbd{M-<} is typed by holding down @key{META}
+and at the same time typing @kbd{<} (which itself is done, on most
+terminals, by holding down @key{SHIFT} and typing @kbd{,}).
address@hidden Input,Meta}.
+
+On some terminals, the @key{META} key is actually labeled @key{ALT}
+or @key{EDIT}.
+
address@hidden Meta Character
+A Meta character is one whose character code includes the Meta bit.
+
address@hidden Minibuffer
+The minibuffer is the window that appears when necessary inside the
+echo area (q.v.@:), used for reading arguments to commands.
address@hidden
+
address@hidden Minibuffer History
+The minibuffer history records the text you have specified in the past
+for minibuffer arguments, so you can conveniently use the same text
+again.  @xref{Minibuffer History}.
+
address@hidden Minor Mode
+A minor mode is an optional feature of Emacs which can be switched on
+or off independently of all other features.  Each minor mode has a
+command to turn it on or off.  @xref{Minor Modes}.
+
address@hidden Minor Mode Keymap
+A minor mode keymap is a keymap that belongs to a minor mode and is
+active when that mode is enabled.  Minor mode keymaps take precedence
+over the buffer's local keymap, just as the local keymap takes
+precedence over the global keymap.  @xref{Keymaps}.
+
address@hidden Mode Line
+The mode line is the line at the bottom of each window (q.v.@:), giving
+status information on the buffer displayed in that window.  @xref{Mode
+Line}.
+
address@hidden Modified Buffer
+A buffer (q.v.@:) is modified if its text has been changed since the
+last time the buffer was saved (or since when it was created, if it
+has never been saved).  @xref{Saving}.
+
address@hidden Moving Text
+Moving text means erasing it from one place and inserting it in
+another.  The usual way to move text is by killing (q.v.@:) it and then
+yanking (q.v.@:) it.  @xref{Killing}.
+
address@hidden MULE
+MULE refers to the Emacs features for editing multilingual address@hidden text
+using multibyte characters (q.v.@:).  @xref{International}.
+
address@hidden Multibyte Character
+A multibyte character is a character that takes up several bytes in a
+buffer.  Emacs uses multibyte characters to represent address@hidden text,
+since the number of address@hidden characters is much more than 256.
address@hidden Chars, International Characters}.
+
address@hidden Named Mark
+A named mark is a register (q.v.@:) in its role of recording a
+location in text so that you can move point to that location.
address@hidden
+
address@hidden Narrowing
+Narrowing means creating a restriction (q.v.@:) that limits editing in
+the current buffer to only a part of the text in the buffer.  Text
+outside that part is inaccessible for editing until the boundaries are
+widened again, but it is still there, and saving the file saves it
+all.  @xref{Narrowing}.
+
address@hidden Newline
+Control-J characters in the buffer terminate lines of text and are
+therefore also called newlines.  @xref{Text Characters,Newline}.
+
address@hidden nil
address@hidden t
address@hidden @code{nil}
address@hidden is a value usually interpreted as a logical ``false.''  Its
+opposite is @code{t}, interpreted as ``true.''
+
address@hidden Numeric Argument
+A numeric argument is a number, specified before a command, to change
+the effect of the command.  Often the numeric argument serves as a
+repeat count.  @xref{Arguments}.
+
address@hidden Overwrite Mode
+Overwrite mode is a minor mode.  When it is enabled, ordinary text
+characters replace the existing text after point rather than pushing
+it to the right.  @xref{Minor Modes}.
+
address@hidden Page
+A page is a unit of text, delimited by formfeed characters (@acronym{ASCII}
+control-L, code 014) coming at the beginning of a line.  Some Emacs
+commands are provided for moving over and operating on pages.
address@hidden
+
address@hidden Paragraph
+Paragraphs are the medium-size unit of human-language text.  There are
+special Emacs commands for moving over and operating on paragraphs.
address@hidden
+
address@hidden Parsing
+We say that certain Emacs commands parse words or expressions in the
+text being edited.  Really, all they know how to do is find the other
+end of a word or expression.  @xref{Syntax}.
+
address@hidden Point
+Point is the place in the buffer at which insertion and deletion
+occur.  Point is considered to be between two characters, not at one
+character.  The terminal's cursor (q.v.@:) indicates the location of
+point.  @xref{Point}.
+
address@hidden Prefix Argument
+See `numeric argument.'
+
address@hidden Prefix Key
+A prefix key is a key sequence (q.v.@:) whose sole function is to
+introduce a set of longer key sequences.  @kbd{C-x} is an example of
+prefix key; any two-character sequence starting with @kbd{C-x} is
+therefore a legitimate key sequence.  @xref{Keys}.
+
address@hidden Primary Rmail File
+Your primary Rmail file is the file named @samp{RMAIL} in your home
+directory.  That's where Rmail stores your incoming mail, unless you
+specify a different file name.  @xref{Rmail}.
+
address@hidden Primary Selection
+The primary selection is one particular X selection (q.v.@:); it is the
+selection that most X applications use for transferring text to and from
+other applications.
+
+The Emacs kill commands set the primary selection and the yank command
+uses the primary selection when appropriate.  @xref{Killing}.
+
address@hidden Prompt
+A prompt is text used to ask the user for input.  Displaying a prompt
+is called prompting.  Emacs prompts always appear in the echo area
+(q.v.@:).  One kind of prompting happens when the minibuffer is used to
+read an argument (@pxref{Minibuffer}); the echoing which happens when
+you pause in the middle of typing a multi-character key sequence is also
+a kind of prompting (@pxref{Echo Area}).
+
address@hidden Query-Replace
+Query-replace is an interactive string replacement feature provided by
+Emacs.  @xref{Query Replace}.
+
address@hidden Quitting
+Quitting means canceling a partially typed command or a running
+command, using @kbd{C-g} (or @address@hidden on MS-DOS).  @xref{Quitting}.
+
address@hidden Quoting
+Quoting means depriving a character of its usual special significance.
+The most common kind of quoting in Emacs is with @kbd{C-q}.  What
+constitutes special significance depends on the context and on
+convention.  For example, an ``ordinary'' character as an Emacs command
+inserts itself; so in this context, a special character is any character
+that does not normally insert itself (such as @key{DEL}, for example),
+and quoting it makes it insert itself as if it were not special.  Not
+all contexts allow quoting.  @xref{Inserting Text,Quoting}.
+
address@hidden Quoting File Names
+Quoting a file name turns off the special significance of constructs
+such as @samp{$}, @samp{~} and @samp{:}.  @xref{Quoted File Names}.
+
address@hidden Read-Only Buffer
+A read-only buffer is one whose text you are not allowed to change.
+Normally Emacs makes buffers read-only when they contain text which
+has a special significance to Emacs; for example, Dired buffers.
+Visiting a file that is write-protected also makes a read-only buffer.
address@hidden
+
address@hidden Rectangle
+A rectangle consists of the text in a given range of columns on a given
+range of lines.  Normally you specify a rectangle by putting point at
+one corner and putting the mark at the diagonally opposite corner.
address@hidden
+
address@hidden Recursive Editing Level
+A recursive editing level is a state in which part of the execution of
+a command involves asking you to edit some text.  This text may
+or may not be the same as the text to which the command was applied.
+The mode line indicates recursive editing levels with square brackets
+(@samp{[} and @samp{]}).  @xref{Recursive Edit}.
+
address@hidden Redisplay
+Redisplay is the process of correcting the image on the screen to
+correspond to changes that have been made in the text being edited.
address@hidden,Redisplay}.
+
address@hidden Regexp
+See `regular expression.'
+
address@hidden Region
+The region is the text between point (q.v.@:) and the mark (q.v.@:).
+Many commands operate on the text of the region.  @xref{Mark,Region}.
+
address@hidden Register
+Registers are named slots in which text or buffer positions or
+rectangles can be saved for later use.  @xref{Registers}.  A related
+Emacs feature is `bookmarks' (q.v.@:).
+
address@hidden Regular Expression
+A regular expression is a pattern that can match various text strings;
+for example, @samp{a[0-9]+} matches @samp{a} followed by one or more
+digits.  @xref{Regexps}.
+
address@hidden Remote File
+A remote file is a file that is stored on a system other than your own.
+Emacs can access files on other computers provided that they are
+connected to the same network as your machine, and (obviously) that
+you have a supported method to gain access to those files.
address@hidden Files}.
+
address@hidden Repeat Count
+See `numeric argument.'
+
address@hidden Replacement
+See `global substitution.'
+
address@hidden Restriction
+A buffer's restriction is the amount of text, at the beginning or the
+end of the buffer, that is temporarily inaccessible.  Giving a buffer a
+nonzero amount of restriction is called narrowing (q.v.@:); removing
+a restriction is called widening (q.v.@:).  @xref{Narrowing}.
+
address@hidden @key{RET}
address@hidden is a character that in Emacs runs the command to insert a
+newline into the text.  It is also used to terminate most arguments
+read in the minibuffer (q.v.@:).  @xref{User Input,Return}.
+
address@hidden Reverting
+Reverting means returning to the original state.  Emacs lets you
+revert a buffer by re-reading its file from disk.  @xref{Reverting}.
+
address@hidden Rmail File
+An Rmail file is a file containing text in a special format used by
+Rmail for storing mail.  @xref{Rmail}.
+
address@hidden Saving
+Saving a buffer means copying its text into the file that was visited
+(q.v.@:) in that buffer.  This is the way text in files actually gets
+changed by your Emacs editing.  @xref{Saving}.
+
address@hidden Scroll Bar
+A scroll bar is a tall thin hollow box that appears at the side of a
+window.  You can use mouse commands in the scroll bar to scroll the
+window.  The scroll bar feature is supported only under windowing
+systems.  @xref{Scroll Bars}.
+
address@hidden Scrolling
+Scrolling means shifting the text in the Emacs window so as to see a
+different part of the buffer.  @xref{Scrolling}.
+
address@hidden Searching
+Searching means moving point to the next occurrence of a specified
+string or the next match for a specified regular expression.
address@hidden
+
address@hidden Search Path
+A search path is a list of directory names, to be used for searching for
+files for certain purposes.  For example, the variable @code{load-path}
+holds a search path for finding Lisp library files.  @xref{Lisp Libraries}.
+
address@hidden Secondary Selection
+The secondary selection is one particular X selection; some X
+applications can use it for transferring text to and from other
+applications.  Emacs has special mouse commands for transferring text
+using the secondary selection.  @xref{Secondary Selection}.

+
address@hidden Selecting a Buffer
+Selecting a buffer means making it the current (q.v.@:) buffer.
address@hidden Buffer}.
+
address@hidden Selection
+Windowing systems allow an application program to specify
+selections whose values are text.  A program can also read the
+selections that other programs have set up.  This is the principal way
+of transferring text between window applications.  Emacs has commands to
+work with the primary (q.v.@:) selection and the secondary (q.v.@:)
+selection, and also with the clipboard (q.v.@:).
+
address@hidden Self-Documentation
+Self-documentation is the feature of Emacs which can tell you what any
+command does, or give you a list of all commands related to a topic
+you specify.  You ask for self-documentation with the help character,
address@hidden  @xref{Help}.
+
address@hidden Self-Inserting Character
+A character is self-inserting if typing that character inserts that
+character in the buffer.  Ordinary printing and whitespace characters
+are self-inserting in Emacs, except in certain special major modes.
+
address@hidden Sentences
+Emacs has commands for moving by or killing by sentences.
address@hidden
+
address@hidden Sexp
+A sexp (short for ``s-expression'') is the basic syntactic unit of
+Lisp in its textual form: either a list, or Lisp atom.  Sexps are also
+the balanced expressions (q.v.@:) of the Lisp language; this is why
+the commands for editing balanced expressions have `sexp' in their
+name.  @xref{Expressions,Sexps}.
+
address@hidden Simultaneous Editing
+Simultaneous editing means two users modifying the same file at once.
+Simultaneous editing, if not detected, can cause one user to lose his
+or her work.  Emacs detects all cases of simultaneous editing, and
+warns one of the users to investigate.
address@hidden,Interlocking,Simultaneous Editing}.
+
address@hidden @key{SPC}
address@hidden is the space character, which you enter by pressing the
+space bar.
+
address@hidden Speedbar
+The speedbar is a special tall frame that provides fast access to Emacs
+buffers, functions within those buffers, Info nodes, and other
+interesting parts of text within Emacs.  @xref{Speedbar}.
+
address@hidden Spell Checking
+Spell checking means checking correctness of the written form of each
+one of the words in a text.  Emacs uses the Ispell spelling-checker
+program to check the spelling of parts of a buffer via a convenient user
+interface.  @xref{Spelling}.
+
address@hidden String
+A string is a kind of Lisp data object which contains a sequence of
+characters.  Many Emacs variables are intended to have strings as
+values.  The Lisp syntax for a string consists of the characters in the
+string with a @samp{"} before and another @samp{"} after.  A @samp{"}
+that is part of the string must be written as @samp{\"} and a @samp{\}
+that is part of the string must be written as @samp{\\}.  All other
+characters, including newline, can be included just by writing them
+inside the string; however, backslash sequences as in C, such as
address@hidden for newline or @samp{\241} using an octal character code, are
+allowed as well.
+
address@hidden String Substitution
+See `global substitution'.
+
address@hidden Syntax Highlighting
+See `font lock.'
+
address@hidden Syntax Table
+The syntax table tells Emacs which characters are part of a word,
+which characters balance each other like parentheses, etc.
address@hidden
+
address@hidden Super
+Super is the name of a modifier bit which a keyboard input character may
+have.  To make a character Super, type it while holding down the
address@hidden key.  Such characters are given names that start with
address@hidden (usually written @kbd{s-} for short).  @xref{User Input,
+Super}.
+
address@hidden Suspending
+Suspending Emacs means stopping it temporarily and returning control
+to its parent process, which is usually a shell.  Unlike killing a job
+(q.v.@:), you can later resume the suspended Emacs job without losing
+your buffers, unsaved edits, undo history, etc.  @xref{Exiting}.
+
address@hidden @key{TAB}
address@hidden is the tab character.  In Emacs it is typically used for
+indentation or completion.
+
address@hidden Tags Table
+A tags table is a file that serves as an index to the function
+definitions in one or more other files.  @xref{Tags}.
+
address@hidden Termscript File
+A termscript file contains a record of all characters sent by Emacs to
+the terminal.  It is used for tracking down bugs in Emacs redisplay.
+Emacs does not make a termscript file unless you tell it to.
address@hidden
+
address@hidden Text
+`Text' has two meanings (@pxref{Text}):
+
address@hidden @bullet
address@hidden
+Data consisting of a sequence of characters, as opposed to binary
+numbers, executable programs, and the like.  The basic contents of an
+Emacs buffer (aside from the text properties, q.v.@:) are always text
+in this sense.
address@hidden
+Data consisting of written human language, as opposed to programs,
+or following the stylistic conventions of human language.
address@hidden itemize
+
address@hidden Text-only Terminal
+A text-only terminal is a display that is limited to displaying text in
+character units.  Such a terminal cannot control individual pixels it
+displays.  Emacs supports a subset of display features on text-only
+terminals.
+
address@hidden Text Properties
+Text properties are annotations recorded for particular characters in
+the buffer.  Images in the buffer are recorded as text properties;
+they also specify formatting information.  @xref{Editing Format Info}.
+
address@hidden Tool Bar
+The tool bar is a line (sometimes multiple lines) of icons at the top
+of an Emacs frame.  Clicking on one of these icons executes a command.
+You can think of this as a graphical relative of the menu bar (q.v.@:).
address@hidden Bars}.
+
address@hidden Tooltips
+Tooltips are small windows displaying a help echo (q.v.@:) text that
+explains parts of the display, lists useful options available via mouse
+clicks, etc.  @xref{Tooltips}.
+
address@hidden Top Level
+Top level is the normal state of Emacs, in which you are editing the
+text of the file you have visited.  You are at top level whenever you
+are not in a recursive editing level (q.v.@:) or the minibuffer
+(q.v.@:), and not in the middle of a command.  You can get back to top
+level by aborting (q.v.@:) and quitting (q.v.@:).  @xref{Quitting}.
+
address@hidden Transposition
+Transposing two units of text means putting each one into the place
+formerly occupied by the other.  There are Emacs commands to transpose
+two adjacent characters, words, balanced expressions (q.v.@:) or lines
+(@pxref{Transpose}).

address@hidden User Option
+A user option is a face (q.v.@:) or a variable (q.v.@:) that exists so
+that you can customize Emacs by setting it to a new value.
address@hidden Customization}.
+
address@hidden Variable
+A variable is an object in Lisp that can store an arbitrary value.
+Emacs uses some variables for internal purposes, and has others (known
+as `user options' (q.v.@:)) just so that you can set their values to
+control the behavior of Emacs.  The variables used in Emacs that you
+are likely to be interested in are listed in the Variables Index in
+this manual (@pxref{Variable Index}).  @xref{Variables}, for
+information on variables.

+
address@hidden Visiting
+Visiting a file means loading its contents into a buffer (q.v.@:)
+where they can be edited.  @xref{Visiting}.
+
address@hidden Whitespace
+Whitespace is any run of consecutive formatting characters (space,
+tab, newline, and backspace).
+
address@hidden Widening
+Widening is removing any restriction (q.v.@:) on the current buffer;
+it is the opposite of narrowing (q.v.@:).  @xref{Narrowing}.
+
address@hidden Window
+Emacs divides a frame (q.v.@:) into one or more windows, each of which
+can display the contents of one buffer (q.v.@:) at any time.
address@hidden, for basic information on how Emacs uses the screen.
address@hidden, for commands to control the use of windows.  Some
+other editors use the term ``window'' for what we call a `frame'

+
address@hidden Word Search
+Word search is searching for a sequence of words, considering the
+punctuation between them as insignificant.  @xref{Word Search}.
+
address@hidden WYSIWYG
+WYSIWYG stands for ``What you see is what you get.''  Emacs generally
+provides WYSIWYG editing for files of characters; in Enriched mode
+(@pxref{Formatted Text}), it provides WYSIWYG editing for files that
+include text formatting information.
