address@hidden expansion (of abbrevs)
-
-  A defined @dfn{abbrev} is a word which @dfn{expands}, if you insert
-it, into some different text.  Abbrevs are defined by the user to expand
-in specific ways.  For example, you might define @samp{foo} as an abbrev
-expanding to @samp{find outer otter}.  Then you could insert
address@hidden outer otter } into the buffer by typing @kbd{f o o
address@hidden
-
-  A second kind of abbreviation facility is called @dfn{dynamic abbrev
-expansion}.  You use dynamic abbrev expansion with an explicit command
-to expand the letters in the buffer before point by looking for other
-words in the buffer that start with those letters.  @xref{Dynamic
-Abbrevs}.

address@hidden Abbrev Concepts
address@hidden Abbrev Concepts
-
-  An @dfn{abbrev} is a word which has been defined to @dfn{expand} into
-a specified @dfn{expansion}.  When you insert a word-separator character
-following the abbrev, that expands the abbrev---replacing the abbrev
-with its expansion.  For example, if @samp{foo} is defined as an abbrev
-expanding to @samp{find outer otter}, then you can insert @samp{find
-outer otter.} into the buffer by typing @kbd{f o o .}.

address@hidden abbrev-mode
address@hidden abbrev-mode
address@hidden Abbrev mode
address@hidden mode, Abbrev
-  Abbrevs expand only when Abbrev mode (a minor mode) is enabled.
-Disabling Abbrev mode does not cause abbrev definitions to be forgotten,
-but they do not expand until Abbrev mode is enabled again.  The command
address@hidden abbrev-mode} toggles Abbrev mode; with a numeric argument, it
-turns Abbrev mode on if the argument is positive, off otherwise.
address@hidden Modes}.  @code{abbrev-mode} is also a variable; Abbrev mode is
-on when the variable is address@hidden  The variable @code{abbrev-mode}
-automatically becomes local to the current buffer when it is set.
-
-  Abbrevs can have @dfn{mode-specific} definitions, active only in one major
-mode.  Abbrevs can also have @dfn{global} definitions that are active in
-all major modes.  The same abbrev can have a global definition and various
-mode-specific definitions for different major modes.  A mode-specific
-definition for the current major mode overrides a global definition.
-
-  You can define abbrevs interactively during the editing session.  You
-can also save lists of abbrev definitions in files for use in later
-sessions.  Some users keep extensive lists of abbrevs that they load
-in every session.

address@hidden Defining Abbrevs
address@hidden Defining Abbrevs
-
address@hidden @kbd
address@hidden C-x a g
-Define an abbrev, using one or more words before point as its expansion
-(@code{add-global-abbrev}).
address@hidden C-x a l
-Similar, but define an abbrev specific to the current major mode
-(@code{add-mode-abbrev}).
address@hidden C-x a i g
-Define a word in the buffer as an abbrev (@code{inverse-add-global-abbrev}).
address@hidden C-x a i l
-Define a word in the buffer as a mode-specific abbrev
-(@code{inverse-add-mode-abbrev}).
address@hidden M-x define-global-abbrev @key{RET} @var{abbrev} @key{RET} 
@var{exp} @key{RET}
-Define @var{abbrev} as an abbrev expanding into @var{exp}.
address@hidden M-x define-mode-abbrev @key{RET} @var{abbrev} @key{RET} 
@var{exp} @key{RET}
-Define @var{abbrev} as a mode-specific abbrev expanding into @var{exp}.
address@hidden M-x kill-all-abbrevs
-Discard all abbrev definitions, leaving a blank slate.
address@hidden table
-
address@hidden C-x a g
address@hidden add-global-abbrev
-  The usual way to define an abbrev is to enter the text you want the
-abbrev to expand to, position point after it, and type @kbd{C-x a g}
-(@code{add-global-abbrev}).  This reads the abbrev itself using the
-minibuffer, and then defines it as an abbrev for one or more words before
-point.  Use a numeric argument to say how many words before point should be
-taken as the expansion.  For example, to define the abbrev @samp{foo} as
-mentioned above, insert the text @samp{find outer otter} and then type
address@hidden 3 C-x a g f o o @key{RET}}.
-
-  An argument of zero to @kbd{C-x a g} means to use the contents of the
-region as the expansion of the abbrev being defined.
-
address@hidden C-x a l
address@hidden add-mode-abbrev
-  The command @kbd{C-x a l} (@code{add-mode-abbrev}) is similar, but
-defines a mode-specific abbrev.  Mode-specific abbrevs are active only in a
-particular major mode.  @kbd{C-x a l} defines an abbrev for the major mode
-in effect at the time @kbd{C-x a l} is typed.  The arguments work the same
-as for @kbd{C-x a g}.
-
address@hidden C-x a i g
address@hidden inverse-add-global-abbrev
address@hidden C-x a i l
address@hidden inverse-add-mode-abbrev
-  If the abbrev text itself is already in the buffer, you can use the
-commands @kbd{C-x a i g} (@code{inverse-add-global-abbrev}) and
address@hidden a i l} (@code{inverse-add-mode-abbrev}) to define it as an
-abbrev by specify the expansion in the minibuffer.  These commands are
-called ``inverse'' because they invert the meaning of the two text
-strings they use (one from the buffer and one read with the
-minibuffer).
-
address@hidden define-mode-abbrev
address@hidden define-global-abbrev
-  You can define an abbrev without inserting either the abbrev or its
-expansion in the buffer using the command @code{define-global-abbrev}.
-It reads two arguments---the abbrev, and its expansion.  The command
address@hidden does likewise for a mode-specific abbrev.
-
-  To change the definition of an abbrev, just define a new definition.
-When the abbrev has a prior definition, the abbrev definition commands
-ask for confirmation before replacing it.
-
address@hidden kill-all-abbrevs
-  To remove an abbrev definition, give a negative argument to the
-abbrev definition command: @kbd{C-u - C-x a g} or @kbd{C-u - C-x a l}.
-The former removes a global definition, while the latter removes a
-mode-specific definition.  @kbd{M-x kill-all-abbrevs} removes all
-abbrev definitions, both global and local.
-
address@hidden Expanding Abbrevs
address@hidden Controlling Abbrev Expansion
-
-  When Abbrev mode is enabled, an abbrev expands whenever it is
-present in the buffer just before point and you type a self-inserting
-whitespace or punctuation character (@key{SPC}, comma, etc.@:).  More
-precisely, any character that is not a word constituent expands an
-abbrev, and any word-constituent character can be part of an abbrev.
-The most common way to use an abbrev is to insert it and then insert a
-punctuation or whitespace character to expand it.
-
address@hidden abbrev-all-caps
-  Abbrev expansion preserves case; thus, @samp{foo} expands into @samp{find
-outer otter}; @samp{Foo} into @samp{Find outer otter}, and @samp{FOO} into
address@hidden OUTER OTTER} or @samp{Find Outer Otter} according to the
-variable @code{abbrev-all-caps} (setting it address@hidden specifies
address@hidden OUTER OTTER}).
-
-  These commands are used to control abbrev expansion:
-
address@hidden @kbd
address@hidden M-'
-Separate a prefix from a following abbrev to be expanded
-(@code{abbrev-prefix-mark}).
address@hidden C-x a e
address@hidden expand-abbrev
-Expand the abbrev before point (@code{expand-abbrev}).
-This is effective even when Abbrev mode is not enabled.
address@hidden M-x expand-region-abbrevs
-Expand some or all abbrevs found in the region.
address@hidden table
-
address@hidden M-'
address@hidden abbrev-prefix-mark
-  You may wish to expand an abbrev and attach a prefix to the expansion;
-for example, if @samp{cnst} expands into @samp{construction}, you might want
-to use it to enter @samp{reconstruction}.  It does not work to type
address@hidden, because that is not necessarily a defined abbrev.  What
-you can do is use the command @kbd{M-'} (@code{abbrev-prefix-mark}) in
-between the prefix @samp{re} and the abbrev @samp{cnst}.  First, insert
address@hidden  Then type @kbd{M-'}; this inserts a hyphen in the buffer to
-indicate that it has done its work.  Then insert the abbrev @samp{cnst};
-the buffer now contains @samp{re-cnst}.  Now insert a non-word character
-to expand the abbrev @samp{cnst} into @samp{construction}.  This
-expansion step also deletes the hyphen that indicated @kbd{M-'} had been
-used.  The result is the desired @samp{reconstruction}.
-
-  If you actually want the text of the abbrev in the buffer, rather than
-its expansion, you can accomplish this by inserting the following
-punctuation with @kbd{C-q}.  Thus, @kbd{foo C-q ,} leaves @samp{foo,} in
-the buffer, not expanding it.
-
address@hidden unexpand-abbrev
-  If you expand an abbrev by mistake, you can undo the expansion and
-bring back the abbrev itself by typing @kbd{C-_} to undo (@pxref{Undo}).
-This also undoes the insertion of the non-word character that expanded
-the abbrev.  If the result you want is the terminating non-word
-character plus the unexpanded abbrev, you must reinsert the terminating
-character, quoting it with @kbd{C-q}.  You can also use the command
address@hidden unexpand-abbrev} to cancel the last expansion without
-deleting the terminating character.
-
address@hidden expand-region-abbrevs
-  @kbd{M-x expand-region-abbrevs} searches through the region for defined
-abbrevs, and for each one found offers to replace it with its expansion.
-This command is useful if you have typed in text using abbrevs but forgot
-to turn on Abbrev mode first.  It may also be useful together with a
-special set of abbrev definitions for making several global replacements at
-once.  This command is effective even if Abbrev mode is not enabled.
-
-  Expanding any abbrev first runs the hook @code{pre-abbrev-expand-hook}
-(@pxref{Hooks}).
-

address@hidden Editing Abbrevs
address@hidden Examining and Editing Abbrevs
-
address@hidden @kbd
address@hidden M-x list-abbrevs
-Display a list of all abbrev definitions.  With a numeric argument, list
-only local abbrevs.
address@hidden M-x edit-abbrevs
-Edit a list of abbrevs; you can add, alter or remove definitions.
address@hidden table
-
address@hidden list-abbrevs
-  The output from @kbd{M-x list-abbrevs} looks like this:
-
address@hidden
address@hidden other address@hidden
-(lisp-mode-abbrev-table)
-"dk"          0    "define-key"
-(global-abbrev-table)
-"dfn"         0    "definition"
address@hidden example
-
address@hidden
-(Some blank lines of no semantic significance, and some other abbrev
-tables, have been omitted.)
-
-  A line containing a name in parentheses is the header for abbrevs in a
-particular abbrev table; @code{global-abbrev-table} contains all the global
-abbrevs, and the other abbrev tables that are named after major modes
-contain the mode-specific abbrevs.
-
-  Within each abbrev table, each nonblank line defines one abbrev.  The
-word at the beginning of the line is the abbrev.  The number that
-follows is the number of times the abbrev has been expanded.  Emacs
-keeps track of this to help you see which abbrevs you actually use, so
-that you can eliminate those that you don't use often.  The string at
-the end of the line is the expansion.
-
-  Some abbrevs are marked with @samp{(sys)}.  These ``system'' abbrevs
-(@pxref{Abbrevs,,, elisp, The Emacs Lisp Reference Manual}) are
-pre-defined by various modes, and are not saved to your abbrev file.
-To disable a ``system'' abbrev, define an abbrev of the same name that
-expands to itself, and save it to your abbrev file.
-
address@hidden edit-abbrevs
address@hidden C-c C-c @r{(Edit Abbrevs)}
-  @kbd{M-x edit-abbrevs} allows you to add, change or kill abbrev
-definitions by editing a list of them in an Emacs buffer.  The list has
-the same format described above.  The buffer of abbrevs is called
address@hidden, and is in Edit-Abbrevs mode.  Type @kbd{C-c C-c} in
-this buffer to install the abbrev definitions as specified in the
-buffer---and delete any abbrev definitions not listed.
-
-  The command @code{edit-abbrevs} is actually the same as
address@hidden except that it selects the buffer @samp{*Abbrevs*}
-whereas @code{list-abbrevs} merely displays it in another window.
-
address@hidden Saving Abbrevs
address@hidden Saving Abbrevs
-
-  These commands allow you to keep abbrev definitions between editing
-sessions.
-
address@hidden @kbd
address@hidden M-x write-abbrev-file @key{RET} @var{file} @key{RET}
-Write a file @var{file} describing all defined abbrevs.
address@hidden M-x read-abbrev-file @key{RET} @var{file} @key{RET}
-Read the file @var{file} and define abbrevs as specified therein.
address@hidden M-x quietly-read-abbrev-file @key{RET} @var{file} @key{RET}
-Similar but do not display a message about what is going on.
address@hidden M-x define-abbrevs
-Define abbrevs from definitions in current buffer.
address@hidden M-x insert-abbrevs
-Insert all abbrevs and their expansions into current buffer.
address@hidden table
-
address@hidden write-abbrev-file
-  @kbd{M-x write-abbrev-file} reads a file name using the minibuffer and
-then writes a description of all current abbrev definitions into that
-file.  This is used to save abbrev definitions for use in a later
-session.  The text stored in the file is a series of Lisp expressions
-that, when executed, define the same abbrevs that you currently have.
-
address@hidden read-abbrev-file
address@hidden quietly-read-abbrev-file
address@hidden abbrev-file-name
-  @kbd{M-x read-abbrev-file} reads a file name using the minibuffer
-and then reads the file, defining abbrevs according to the contents of
-the file.  The function @code{quietly-read-abbrev-file} is similar
-except that it does not display a message in the echo area; you cannot
-invoke it interactively, and it is used primarily in the @file{.emacs}
-file.  If either of these functions is called with @code{nil} as the
-argument, it uses the file name specified in the variable
address@hidden, which is by default @code{"~/.abbrev_defs"}.
-That file is your standard abbrev definition file, and Emacs loads
-abbrevs from it automatically when it starts up.
-
address@hidden save-abbrevs
-  Emacs will offer to save abbrevs automatically if you have changed
-any of them, whenever it offers to save all files (for @kbd{C-x s} or
address@hidden C-c}).  It saves them in the file specified by
address@hidden  This feature can be inhibited by setting the
-variable @code{save-abbrevs} to @code{nil}.
-
address@hidden insert-abbrevs
address@hidden define-abbrevs
-  The commands @kbd{M-x insert-abbrevs} and @kbd{M-x define-abbrevs} are
-similar to the previous commands but work on text in an Emacs buffer.
address@hidden insert-abbrevs} inserts text into the current buffer after point,
-describing all current abbrev definitions; @kbd{M-x define-abbrevs} parses
-the entire current buffer and defines abbrevs accordingly.
-
address@hidden Dynamic Abbrevs
address@hidden Dynamic Abbrev Expansion
-
-  The abbrev facility described above operates automatically as you
-insert text, but all abbrevs must be defined explicitly.  By contrast,
address@hidden abbrevs} allow the meanings of abbreviations to be
-determined automatically from the contents of the buffer, but dynamic
-abbrev expansion happens only when you request it explicitly.
-
address@hidden M-/
address@hidden C-M-/
address@hidden dabbrev-expand
address@hidden dabbrev-completion
address@hidden @kbd
address@hidden M-/
-Expand the word in the buffer before point as a @dfn{dynamic abbrev},
-by searching in the buffer for words starting with that abbreviation
-(@code{dabbrev-expand}).
-
address@hidden C-M-/
-Complete the word before point as a dynamic abbrev
-(@code{dabbrev-completion}).
address@hidden table
-
address@hidden dabbrev-limit
-  For example, if the buffer contains @samp{does this follow } and you
-type @kbd{f o M-/}, the effect is to insert @samp{follow} because that
-is the last word in the buffer that starts with @samp{fo}.  A numeric
-argument to @kbd{M-/} says to take the second, third, etc.@: distinct
-expansion found looking backward from point.  Repeating @kbd{M-/}
-searches for an alternative expansion by looking farther back.  After
-scanning all the text before point, it searches the text after point.
-The variable @code{dabbrev-limit}, if address@hidden, specifies how far
-away in the buffer to search for an expansion.
-
address@hidden dabbrev-check-all-buffers
-  After scanning the current buffer, @kbd{M-/} normally searches other
-buffers, unless you have set @code{dabbrev-check-all-buffers} to
address@hidden
-
address@hidden dabbrev-ignored-buffer-regexps
-  For finer control over which buffers to scan, customize the variable
address@hidden  Its value is a list of regular
-expressions.  If a buffer's name matches any of these regular
-expressions, dynamic abbrev expansion skips that buffer.
-
-  A negative argument to @kbd{M-/}, as in @kbd{C-u - M-/}, says to
-search first for expansions after point, then other buffers, and
-consider expansions before point only as a last resort.  If you repeat
-the @kbd{M-/} to look for another expansion, do not specify an
-argument.  Repeating @kbd{M-/} cycles through all the expansions after
-point and then the expansions before point.
-
-  After you have expanded a dynamic abbrev, you can copy additional
-words that follow the expansion in its original context.  Simply type
address@hidden@key{SPC} M-/} for each additional word you want to copy.  The
-spacing and punctuation between words is copied along with the words.
-
-  The command @kbd{C-M-/} (@code{dabbrev-completion}) performs
-completion of a dynamic abbrev.  Instead of trying the possible
-expansions one by one, it finds all of them, then inserts the text
-that they have in common.  If they have nothing in common, @kbd{C-M-/}
-displays a list of completions, from which you can select a choice in
-the usual manner.  @xref{Completion}.
-
-  Dynamic abbrev expansion is completely independent of Abbrev mode; the
-expansion of a word with @kbd{M-/} is completely independent of whether
-it has a definition as an ordinary abbrev.
-
address@hidden Dabbrev Customization
address@hidden Customizing Dynamic Abbreviation
-
-  Normally, dynamic abbrev expansion ignores case when searching for
-expansions.  That is, the expansion need not agree in case with the word
-you are expanding.
-
address@hidden dabbrev-case-fold-search
-  This feature is controlled by the variable
address@hidden  If it is @code{t}, case is ignored in
-this search; if it is @code{nil}, the word and the expansion must match
-in case.  If the value of @code{dabbrev-case-fold-search} is
address@hidden, which is true by default, then the variable
address@hidden controls whether to ignore case while searching
-for expansions.
-
address@hidden dabbrev-case-replace
-  Normally, dynamic abbrev expansion preserves the case pattern
address@hidden the dynamic abbrev you are expanding}, by converting the
-expansion to that case pattern.
-
address@hidden dabbrev-case-fold-search
-  The variable @code{dabbrev-case-replace} controls whether to
-preserve the case pattern of the dynamic abbrev.  If it is @code{t},
-the dynamic abbrev's case pattern is preserved in most cases; if it is
address@hidden, the expansion is always copied verbatim.  If the value of
address@hidden is @code{case-replace}, which is true by
-default, then the variable @code{case-replace} controls whether to
-copy the expansion verbatim.
-
-  However, if the expansion contains a complex mixed case pattern, and
-the dynamic abbrev matches this pattern as far as it goes, then the
-expansion is always copied verbatim, regardless of those variables.
-Thus, for example, if the buffer contains
address@hidden, and you type @kbd{v a M-/}, it
-copies the expansion verbatim including its case pattern.
-
address@hidden dabbrev-abbrev-char-regexp
-  The variable @code{dabbrev-abbrev-char-regexp}, if address@hidden,
-controls which characters are considered part of a word, for dynamic expansion
-purposes.  The regular expression must match just one character, never
-two or more.  The same regular expression also determines which
-characters are part of an expansion.  The value @code{nil} has a special
-meaning: dynamic abbrevs are made of word characters, but expansions are
-made of word and symbol characters.
-
address@hidden dabbrev-abbrev-skip-leading-regexp
-  In shell scripts and makefiles, a variable name is sometimes prefixed
-with @samp{$} and sometimes not.  Major modes for this kind of text can
-customize dynamic abbrev expansion to handle optional prefixes by setting
-the variable @code{dabbrev-abbrev-skip-leading-regexp}.  Its value
-should be a regular expression that matches the optional prefix that
-dynamic abbrev expression should ignore.
