-@kindex C-h
-@kindex F1
-
- Emacs provides extensive help features accessible through a single
-character, @kbd{C-h}. @kbd{C-h} is a prefix key that is used only for
-documentation-printing commands. The characters that you can type after
-@kbd{C-h} are called @dfn{help options}. One help option is @kbd{C-h};
-that is how you ask for help about using @kbd{C-h}. To cancel, type
-@kbd{C-g}. The function key @key{F1} is equivalent to @kbd{C-h}.
-
-@kindex C-h C-h
-@findex help-for-help
- @kbd{C-h C-h} (@code{help-for-help}) displays a list of the possible
-help options, each with a brief description. Before you type a help
-option, you can use @key{SPC} or @key{DEL} to scroll through the list.
-
- @kbd{C-h} or @key{F1} means ``help'' in various other contexts as
-well. For example, in the middle of @code{query-replace}, it describes
-the options available for how to operate on the current match. After a
-prefix key, it displays a list of the alternatives that can follow the
-prefix key. (A few prefix keys don't support @kbd{C-h}, because they
-define other meanings for it, but they all support @key{F1}.)
-
- Most help buffers use a special major mode, Help mode, which lets you
-scroll conveniently with @key{SPC} and @key{DEL}. It also offers
-hyperlinks to further help regarding cross-referenced names, Info nodes,
-customization buffers and the like. @xref{Help Mode}.
-
-@cindex searching documentation efficiently
-@cindex looking for a subject in documentation
- If you are looking for a certain feature, but don't know where
-exactly it is documented, and aren't even sure what is the name of the
-related command or option, we recommend trying these methods. Usually
-it is best to start with an apropos command, then try searching the
-manual index, then finally look in the FAQ and the package keywords.
-
-@table @kbd
-@item C-h a @var{topic} @key{RET}
-This searches for commands whose names match @var{topic}, which should
-be a regular expression (@pxref{Regexps}). Browse the buffer popped
-up by Emacs, to find what you are looking for. @xref{Apropos}.
-
-@item M-x apropos @key{RET} @var{topic} @key{RET}
-This works like @kbd{C-h a}, but it also searches for user options and
-other variables, in case the feature you are looking for is controlled
-by an option, not a command. @xref{Apropos}.
-
-@item M-x apropos-documentation @key{RET} @var{topic} @key{RET}
-This searches the @emph{documentation strings} (the built-in short
-descriptions) of all variables and functions (not their names) for a
-match for @var{topic}, a regular expression. @xref{Apropos}.
-
-@item C-h i d m emacs @key{RET} i @var{topic} @key{RET}
-This looks up @var{topic} in the indices of the Emacs on-line manual.
-If there are several matches, Emacs displays the first one. You can then
-press @key{,} to move to other matches, until you find what you are
-looking for.
-
-@item C-h i d m emacs @key{RET} s @var{topic} @key{RET}
-Similar, but searches for @var{topic} (which can be a regular
-expression) in the @emph{text} of the manual rather than in its
-indices.
-
-@item C-h F
-This brings up the Emacs FAQ, where you can use the usual search
-commands (@pxref{Search}) to find the information.
-
-@item C-h p
-Finally, you can try looking up a suitable package using keywords
-pertinent to the feature you need. @xref{Library Keywords}.

-
-@kindex C-h c
-@findex describe-key-briefly
- The most basic @kbd{C-h} options are @kbd{C-h c}
-(@code{describe-key-briefly}) and @w{@kbd{C-h k}} (@code{describe-key}).
-@kbd{C-h c @var{key}} prints in the echo area the name of the command
-that @var{key} is bound to. For example, @kbd{C-h c C-f} prints
-@samp{forward-char}. Since command names are chosen to describe what
-the commands do, this is a good way to get a very brief description of
-what @var{key} does.
-
-@kindex C-h k
-@findex describe-key
- @kbd{C-h k @var{key}} is similar but gives more information: it
-displays the documentation string of the command as well as its name.
-This is too big for the echo area, so a window is used for the display.
-
- @kbd{C-h c} and @kbd{C-h k} work for any sort of key sequences,
-including function keys and mouse events.
-
-@node Name Help
-@section Help by Command or Variable Name
-
-@kindex C-h f
-@findex describe-function
- @kbd{C-h f} (@code{describe-function}) reads the name of a Lisp function
-using the minibuffer, then displays that function's documentation string
-in a window. Since commands are Lisp functions, you can use this to get
-the documentation of a command that you know by name. For example,
-
-@example
-C-h f auto-fill-mode @key{RET}
-@end example
-
-@noindent
-displays the documentation of @code{auto-fill-mode}. This is the only
-way to get the documentation of a command that is not bound to any key
-(one which you would normally run using @kbd{M-x}).
-
- @kbd{C-h f} is also useful for Lisp functions that you are planning to
-use in a Lisp program. For example, if you have just written the
-expression @code{(make-vector len)} and want to check that you are using
-@code{make-vector} properly, type @kbd{C-h f make-vector @key{RET}}.
-Because @kbd{C-h f} allows all function names, not just command names,
-you may find that some of your favorite abbreviations that work in
-@kbd{M-x} don't work in @kbd{C-h f}. An abbreviation may be unique
-among command names yet fail to be unique when other function names are
-allowed.
-
- The function name for @kbd{C-h f} to describe has a default which is
-used if you type @key{RET} leaving the minibuffer empty. The default is
-the function called by the innermost Lisp expression in the buffer around
-point, @emph{provided} that is a valid, defined Lisp function name. For
-example, if point is located following the text @samp{(make-vector (car
-x)}, the innermost list containing point is the one that starts with
-@samp{(make-vector}, so the default is to describe the function
-@code{make-vector}.
-
- @kbd{C-h f} is often useful just to verify that you have the right
-spelling for the function name. If @kbd{C-h f} mentions a name from the
-buffer as the default, that name must be defined as a Lisp function. If
-that is all you want to know, just type @kbd{C-g} to cancel the @kbd{C-h
-f} command, then go on editing.
-
-@kindex C-h w
-@findex where-is
- @kbd{C-h w @var{command} @key{RET}} tells you what keys are bound to
-@var{command}. It prints a list of the keys in the echo area. If it
-says the command is not on any key, you must use @kbd{M-x} to run it.
-@kbd{C-h w} runs the command @code{where-is}.
-
- @kbd{C-h v} (@code{describe-variable}) is like @kbd{C-h f} but describes
-Lisp variables instead of Lisp functions. Its default is the Lisp symbol
-around or before point, but only if that is the name of a known Lisp
-variable. @xref{Variables}.@refill
-
- Help buffers describing variables or functions defined in Lisp
-normally have hyperlinks to the Lisp definition, if you have the Lisp
-source files installed. If you know Lisp, this provides the ultimate
-documentation. If you don't know Lisp, you should learn it. If you
-are treating Emacs as an object file, then you are just @emph{using}
-Emacs. For real intimacy with Emacs, you must read the source code.
-
-@node Apropos
-@section Apropos
-
-@kindex C-h a
-@findex apropos-command
-@cindex apropos
- A more sophisticated sort of question to ask is, ``What are the
-commands for working with files?'' To ask this question, type @kbd{C-h
-a file @key{RET}}, which displays a list of all command names that
-contain @samp{file}, including @code{copy-file}, @code{find-file}, and
-so on. With each command name appears a brief description of how to use
-the command, and what keys you can currently invoke it with. For
-example, it would say that you can invoke @code{find-file} by typing
-@kbd{C-x C-f}. The @kbd{a} in @kbd{C-h a} stands for ``Apropos'';
-@kbd{C-h a} runs the command @code{apropos-command}. This command
-normally checks only commands (interactive functions); if you specify a
-prefix argument, it checks noninteractive functions as well.
-
- Because @kbd{C-h a} looks only for functions whose names contain the
-string you specify, you must use ingenuity in choosing the
-string. If you are looking for commands for killing backwards and
-@kbd{C-h a kill-backwards @key{RET}} doesn't reveal any, don't give up.
-Try just @kbd{kill}, or just @kbd{backwards}, or just @kbd{back}. Be
-persistent. Also note that you can use a regular expression as the
-argument, for more flexibility (@pxref{Regexps}).
-
- Here is a set of arguments to give to @kbd{C-h a} that covers many
-classes of Emacs commands, since there are strong conventions for naming
-the standard Emacs commands. By giving you a feel for the naming
-conventions, this set should also serve to aid you in developing a
-technique for picking @code{apropos} strings.
-
-@quotation
-char, line, word, sentence, paragraph, region, page, sexp, list, defun,
-rect, buffer, frame, window, face, file, dir, register, mode, beginning, end,
-forward, backward, next, previous, up, down, search, goto, kill, delete,
-mark, insert, yank, fill, indent, case, change, set, what, list, find,
-view, describe, default.
-@end quotation
-
-@findex apropos-variable
- To list all user variables that match a regexp, use the command
-@kbd{M-x apropos-variable}. This command shows only user variables and
-customization options by default; if you specify a prefix argument, it
-checks all variables.
-
-@findex apropos
- To list all Lisp symbols that contain a match for a regexp, not just
-the ones that are defined as commands, use the command @kbd{M-x apropos}
-instead of @kbd{C-h a}. This command does not check key bindings by
-default; specify a numeric argument if you want it to check them.
-
-@findex apropos-documentation
- The @code{apropos-documentation} command is like @code{apropos} except
-that it searches documentation strings as well as symbol names for
-matches for the specified regular expression.
-
-@findex apropos-value
- The @code{apropos-value} command is like @code{apropos} except that it
-searches symbols' values for matches for the specified regular
-expression. This command does not check function definitions or
-property lists by default; specify a numeric argument if you want it to
-check them.
-
-@vindex apropos-do-all
- If the variable @code{apropos-do-all} is non-@code{nil}, the commands
-above all behave as if they had been given a prefix argument.
-
- If you want more information about a function definition, variable or
-symbol property listed in the Apropos buffer, you can click on it with
-@kbd{Mouse-2} or move there and type @key{RET}.
-
-@node Library Keywords
-@section Keyword Search for Lisp Libraries
-
-@kindex C-h p
-@findex finder-by-keyword

-@node Language Help
-@section Help for International Language Support
-
- You can use the command @kbd{C-h L}
-(@code{describe-language-environment}) to find out the support for a
-specific language environment. @xref{Language Environments}. This
-tells you which languages this language environment is useful for, and
-lists the character sets, coding systems, and input methods that go with
-it. It also shows some sample text to illustrate scripts.
-
- The command @kbd{C-h h} (@code{view-hello-file}) displays the file
-@file{etc/HELLO}, which shows how to say ``hello'' in many languages.
-
- The command @kbd{C-h I} (@code{describe-input-method}) describes
-information about input methods---either a specified input method, or by
-default the input method in use. @xref{Input Methods}.
-
- The command @kbd{C-h C} (@code{describe-coding-system}) describes
-information about coding systems---either a specified coding system, or
-the ones currently in use. @xref{Coding Systems}.
-
-@node Help Mode
-@section Help Mode Commands
-
- Help buffers provide the commands of View mode (@pxref{Misc File
-Ops}), plus a few special commands of their own.
-
-@table @kbd
-@item @key{SPC}
-Scroll forward.
-@item @key{DEL}
-@itemx @key{BS}
-Scroll backward. On some keyboards, this key is known as @key{BS} or
-@key{backspace}.
-@item @key{RET}
-Follow a cross reference at point.
-@item @key{TAB}
-Move point forward to the next cross reference.
-@item S-@key{TAB}
-Move point back to the previous cross reference.
-@item Mouse-2
-Follow a cross reference that you click on.
-@end table
-
- When a command name (@pxref{M-x,, Running Commands by Name}) or
-variable name (@pxref{Variables}) appears in the documentation, it
-normally appears inside paired single-quotes. You can click on the name
-with @kbd{Mouse-2}, or move point there and type @key{RET}, to view the
-documentation of that command or variable. Use @kbd{C-c C-b} to retrace
-your steps.
-
-@kindex @key{TAB} @r{(Help mode)}
-@findex help-next-ref
-@kindex S-@key{TAB} @r{(Help mode)}
-@findex help-previous-ref
- There are convenient commands for moving point to cross references in
-the help text. @key{TAB} (@code{help-next-ref}) moves point down to the
-next cross reference. Use @kbd{S-@key{TAB}} to move point up to the
-previous cross reference (@code{help-previous-ref}).
-
-@node Misc Help
-@section Other Help Commands
-
-@kindex C-h i
-@findex info
-@cindex Info
-@cindex manuals, on-line
-@cindex on-line manuals
- @kbd{C-h i} (@code{info}) runs the Info program, which is used for
-browsing through structured documentation files. The entire Emacs manual
-is available within Info. Eventually all the documentation of the GNU
-system will be available. Type @kbd{h} after entering Info to run
-a tutorial on using Info.
-
- If you specify a numeric argument, @kbd{C-h i} prompts for the name of
-a documentation file. This way, you can browse a file which doesn't
-have an entry in the top-level Info menu. It is also handy when you
-need to get to the documentation quickly, and you know the exact name of
-the file.
-
-@kindex C-h C-f
-@kindex C-h C-k
-@findex Info-goto-emacs-key-command-node
-@findex Info-goto-emacs-command-node
- There are two special help commands for accessing Emacs documentation
-through Info. @kbd{C-h C-f @var{function} @key{RET}} enters Info and
-goes straight to the documentation of the Emacs function
-@var{function}. @kbd{C-h C-k @var{key}} enters Info and goes straight
-to the documentation of the key @var{key}. These two keys run the
-commands @code{Info-goto-emacs-command-node} and
-@code{Info-goto-emacs-key-command-node}.
-
- When editing a program, if you have an Info version of the manual for
-the programming language, you can use the command @kbd{C-h C-i} to refer
-to the manual documentation for a symbol (keyword, function or
-variable). The details of how this command works depend on the major
-mode.
-
-@kindex C-h l
-@findex view-lossage
- If something surprising happens, and you are not sure what commands you
-typed, use @kbd{C-h l} (@code{view-lossage}). @kbd{C-h l} prints the last
-100 command characters you typed in. If you see commands that you don't
-know, you can use @kbd{C-h c} to find out what they do.
-
-@kindex C-h m
-@findex describe-mode
- Emacs has numerous major modes, each of which redefines a few keys and
-makes a few other changes in how editing works. @kbd{C-h m}
-(@code{describe-mode}) prints documentation on the current major mode,
-which normally describes all the commands that are changed in this
-mode.
-
-@kindex C-h b
-@findex describe-bindings
- @kbd{C-h b} (@code{describe-bindings}) and @kbd{C-h s}
-(@code{describe-syntax}) present other information about the current
-Emacs mode. @kbd{C-h b} displays a list of all the key bindings now in
-effect; the local bindings defined by the current minor modes first,
-then the local bindings defined by the current major mode, and finally
-the global bindings (@pxref{Key Bindings}). @kbd{C-h s} displays the
-contents of the syntax table, with explanations of each character's
-syntax (@pxref{Syntax}).
-
- You can get a similar list for a particular prefix key by typing
-@kbd{C-h} after the prefix key. (There are a few prefix keys for which
-this does not work---those that provide their own bindings for
-@kbd{C-h}. One of these is @key{ESC}, because @kbd{@key{ESC} C-h} is
-actually @kbd{C-M-h}, which marks a defun.)

+ @kbd{C-h} itself is one of the help options; @kbd{C-h C-h} displays
+a list of help options, with a brief description of each one
+(@code{help-for-help}). You can scroll the list with @key{SPC} and
+@key{DEL}, then type the help option you want. To cancel, type
+@kbd{C-g}.
+
+ @kbd{C-h} or @key{F1} means ``help'' in various other contexts as
+well. For instance, you can type them after a prefix key to display
+list of the keys that can follow the prefix key. (A few prefix keys
+don't support @kbd{C-h} in this way, because they define other
+meanings for it, but they all support @key{F1} for help.)
+
+ Most help buffers use a special major mode, Help mode, which lets
+you scroll conveniently with @key{SPC} and @key{DEL}. You can also
+follow hyperlinks to URLs, and to other facilities including Info
+nodes and customization buffers. @xref{Help Mode}.
+
+@cindex searching documentation efficiently
+@cindex looking for a subject in documentation
+ If you are looking for a certain feature, but don't know what it is
+called or where to look, we recommend three methods. First, try an
+apropos command, then try searching the manual index, then look in the
+FAQ and the package keywords.
+
+@table @kbd
+@item C-h a @var{topics} @key{RET}
+This searches for commands whose names match the argument
+@var{topics}. The argument can be a keyword, a list of keywords, or a
+regular expression (@pxref{Regexps}). This command displays all the
+matches in a new buffer. @xref{Apropos}.
+
+@item C-h i d m emacs @key{RET} i @var{topic} @key{RET}
+This searches for @var{topic} in the indices of the on-line Emacs
+manual, and displays the first match found. Press @kbd{,} to see
+subsequent matches. You can use a regular expression as @var{topic}.
+
+@item C-h i d m emacs @key{RET} s @var{topic} @key{RET}
+Similar, but searches the @emph{text} of the manual rather than the
+indices.

+@node Key Help
+@section Documentation for a Key
+
+@kindex C-h c
+@findex describe-key-briefly
+ The help commands to get information about a key sequence are
+@kbd{C-h c} and @w{@kbd{C-h k}}. @kbd{C-h c @var{key}} displays in
+the echo area the name of the command that @var{key} is bound to. For
+example, @kbd{C-h c C-f} displays @samp{forward-char}. Since command
+names are chosen to describe what the commands do, this gives you a
+very brief description of what @var{key} does.
+
+@kindex C-h k
+@findex describe-key
+ @kbd{C-h k @var{key}} is similar but gives more information: it
+displays the documentation string of the command as well as its name.
+It displays this information in a window, since it may not fit in the
+echo area.
+
+@kindex C-h K
+@findex Info-goto-emacs-key-command-node
+ To find the documentation of a key sequence @var{key}, type @kbd{C-h
+K @var{key}}. This displays the appropriate manual section which
+contains the documentation of @var{key}.
+
+ @kbd{C-h c}, @kbd{C-h k} and @kbd{C-h K} work for any sort of key
+sequences, including function keys, menus, and mouse events. For
+instance, after @kbd{C-h k} you can select a menu item from the menu
+bar, to view the documentation string of the command it runs.
+
+@kindex C-h w
+@findex where-is
+ @kbd{C-h w @var{command} @key{RET}} lists the keys that are bound to
+@var{command}. It displays the list in the echo area. If it says the
+command is not on any key, that means you must use @kbd{M-x} to run
+it. @kbd{C-h w} runs the command @code{where-is}.
+
+@node Name Help
+@section Help by Command or Variable Name
+
+@kindex C-h f
+@findex describe-function
+ @kbd{C-h f @var{function} @key{RET}} (@code{describe-function})
+displays the documentation of Lisp function @var{function}, in a
+window. Since commands are Lisp functions, you can use this method to
+view the documentation of any command whose name you know. For
+example,
+
+@example
+C-h f auto-fill-mode @key{RET}
+@end example
+
+@noindent
+displays the documentation of @code{auto-fill-mode}. This is the only
+way to get the documentation of a command that is not bound to any key
+(one which you would normally run using @kbd{M-x}).
+
+ @kbd{C-h f} is also useful for Lisp functions that you use in a Lisp
+program. For example, if you have just written the expression
+@code{(make-vector len)} and want to check that you are using
+@code{make-vector} properly, type @kbd{C-h f make-vector @key{RET}}.
+Because @kbd{C-h f} allows all function names, not just command names,
+you may find that some of your favorite completion abbreviations that
+work in @kbd{M-x} don't work in @kbd{C-h f}. An abbreviation that is
+unique among command names may not be unique among all function names.
+
+ If you type @kbd{C-h f @key{RET}}, it describes the function called
+by the innermost Lisp expression in the buffer around point,
+@emph{provided} that function name is a valid, defined Lisp function.
+(That name appears as the default while you enter the argument.) For
+example, if point is located following the text @samp{(make-vector
+(car x)}, the innermost list containing point is the one that starts
+with @samp{(make-vector}, so @kbd{C-h f @key{RET}} will describe the
+function @code{make-vector}.
+
+ @kbd{C-h f} is also useful just to verify that you spelled a
+function name correctly. If the minibuffer prompt for @kbd{C-h f}
+shows the function name from the buffer as the default, it means that
+name is defined as a Lisp function. Type @kbd{C-g} to cancel the
+@kbd{C-h f} command if you don't really want to view the
+documentation.
+
+@kindex C-h v
+@findex describe-variable
+ @kbd{C-h v} (@code{describe-variable}) is like @kbd{C-h f} but
+describes Lisp variables instead of Lisp functions. Its default is
+the Lisp symbol around or before point, if that is the name of a
+defined Lisp variable. @xref{Variables}.
+
+ Help buffers that describe Emacs variables and functions normally
+have hyperlinks to the corresponding source definition, if you have
+the source files installed. (@xref{Hyperlinking}.) If you know Lisp
+(or C), this provides the ultimate documentation. If you don't know
+Lisp, you should learn it. (The Introduction to Emacs Lisp
+Programming, available from the FSF through fsf.org, is a good way to
+get started.) If Emacs feels you are just @emph{using} it, treating
+it as an object program, its feelings may be hurt. For real intimacy,
+read the Emacs source code.
+
+@kindex C-h F
+@findex Info-goto-emacs-command-node
+ To find a function's documentation in a manual, use @kbd{C-h F}
+(@code{Info-goto-emacs-command-node}). This knows about various
+manuals, not just the Emacs manual, and finds the right one.
+
+@node Apropos
+@section Apropos
+
+ The @dfn{apropos} commands answer questions like, ``What are the
+commands for working with files?'' More precisely, you specify an
+@dfn{apropos pattern}, which means either a word, a list of words, or
+a regular expression. Each apropos command displays a list of items
+that match the pattern, in a separate buffer.
+
+@table @kbd
+@item C-h a @var{pattern} @key{RET}
+Search for commands whose names match @var{pattern}.
+
+@item M-x apropos @key{RET} @var{pattern} @key{RET}
+Search for functions and variables whose names match @var{pattern}.
+Both interactive functions (commands) and noninteractive functions can
+be found by this command.
+
+@item M-x apropos-variable @key{RET} @var{pattern} @key{RET}
+Search for user-option variables whose names match @var{pattern}.
+
+@item M-x apropos-value @key{RET} @var{pattern} @key{RET}
+Search for functions whose definitions @var{pattern}, and variables
+whose values match @var{pattern}.
+
+@item C-h d @var{pattern} @key{RET}
+Search for functions and variables whose @strong{documentation
+strings} match @var{pattern}.
+@end table
+
+@kindex C-h a
+@findex apropos-command
+@cindex apropos
+ The simplest kind of apropos pattern is one word. Anything which
+contains that word matches the pattern. Thus, to find the commands
+that work on files, type @kbd{C-h a file @key{RET}}. This displays a
+list of all command names that contain @samp{file}, including
+@code{copy-file}, @code{find-file}, and so on. Each command name
+comes with a brief description and a list of keys you can currently
+invoke it with. In our example, it would say that you can invoke
+@code{find-file} by typing @kbd{C-x C-f}.
+
+ The @kbd{a} in @kbd{C-h a} stands for ``Apropos''; @kbd{C-h a}
+runs the command @code{apropos-command}. This command normally checks
+only commands (interactive functions); if you specify a prefix
+argument, it checks noninteractive functions as well.
+
+ For more information about a function definition, variable or symbol
+property listed in the apropos buffer, you can click on it with
+@kbd{Mouse-1} or @kbd{Mouse-2}, or move there and type @key{RET}.
+
+ When you specify more than one word in the apropos pattern, a name
+must contain at least two of the words in order to match. Thus, if
+you are looking for commands to kill a chunk of text before point, you
+could try @kbd{C-h a kill back backward behind before @key{RET}}. The
+real command name @code{kill-backward} will match that; if there were
+a command @code{kill-text-before}, it would also match, since it
+contains two of the specified words.
+
+ For even greater flexibility, you can specify a regular expression
+(@pxref{Regexps}). An apropos pattern is interpreted as a regular
+expression if it contains any of the regular expression special
+characters, @samp{^$*+?.\[}.
+
+ Following the conventions for naming Emacs commands, here are some
+words that you'll find useful in apropos patterns. By using them in
+@kbd{C-h a}, you will also get a feel for the naming conventions.
+
+@quotation
+char, line, word, sentence, paragraph, region, page, sexp, list, defun,
+rect, buffer, frame, window, face, file, dir, register, mode, beginning, end,
+forward, backward, next, previous, up, down, search, goto, kill, delete,
+mark, insert, yank, fill, indent, case, change, set, what, list, find,
+view, describe, default.
+@end quotation
+
+@findex apropos
+ Use @kbd{M-x apropos} instead of @kbd{C-h a} to list all the Lisp
+symbols that match an apropos pattern, not just the symbols that are
+commands. This command does not list key bindings by default; specify
+a numeric argument if you want it to list them.
+
+@findex apropos-variable
+ Use @kbd{M-x apropos-variable} to list user-customizable variables
+that match an apropos pattern. If you specify a prefix argument, it
+lists all matching variables.
+
+@kindex C-h d
+@findex apropos-documentation
+ The @code{apropos-documentation} command is like @code{apropos}
+except that it searches documentation strings instead of symbol names
+for matches.
+
+@findex apropos-value
+ The @code{apropos-value} command is like @code{apropos} except that
+it searches variables' values for matches for the apropos pattern.
+With a prefix argument, it also checks symbols' function definitions
+and property lists.
+
+@vindex apropos-do-all
+ If the variable @code{apropos-do-all} is non-@code{nil}, the apropos
+commands always behave as if they had been given a prefix argument.
+
+@vindex apropos-sort-by-scores
+@cindex apropos search results, order by score
+ By default, apropos lists the search results in alphabetical order.
+If the variable @code{apropos-sort-by-scores} is non-@code{nil}, the
+apropos commands try to guess the relevance of each result, and
+display the most relevant ones first.
+
+@vindex apropos-documentation-sort-by-scores
+ By default, apropos lists the search results for
+@code{apropos-documentation} in order of relevance of the match. If
+the variable @code{apropos-documentation-sort-by-scores} is
+@code{nil}, apropos lists the symbols found in alphabetical order.
+
+@node Library Keywords
+@section Keyword Search for Lisp Libraries
+
+@kindex C-h p
+@findex finder-by-keyword
+The @kbd{C-h p} command lets you search the standard Emacs Lisp

+@node Language Help
+@section Help for International Language Support
+
+ You can use the command @kbd{C-h L}
+(@code{describe-language-environment}) to get information about a
+specific language environment. @xref{Language Environments}. This
+tells you which languages this language environment supports. It also
+lists the character sets, coding systems, and input methods that work
+with this language environment, and finally shows some sample text to
+illustrate scripts.
+
+ The command @kbd{C-h h} (@code{view-hello-file}) displays the file
+@file{etc/HELLO}, which shows how to say ``hello'' in many languages.
+
+ The command @kbd{C-h I} (@code{describe-input-method}) describes an
+input method---either a specified input method, or by default the
+input method currently in use. @xref{Input Methods}.
+
+ The command @kbd{C-h C} (@code{describe-coding-system}) describes
+coding systems---either a specified coding system, or the ones
+currently in use. @xref{Coding Systems}.
+
+@node Help Mode
+@section Help Mode Commands
+
+ Help buffers provide the same commands as View mode (@pxref{Misc File
+Ops}), plus a few special commands of their own.
+
+@table @kbd
+@item @key{SPC}
+Scroll forward.
+@item @key{DEL}
+Scroll backward.
+@item @key{RET}
+Follow a cross reference at point.
+@item @key{TAB}
+Move point forward to the next cross reference.
+@item S-@key{TAB}
+Move point back to the previous cross reference.
+@item Mouse-1
+@itemx Mouse-2
+Follow a cross reference that you click on.
+@item C-c C-c
+Show all documentation about the symbol at point.
+@end table
+
+ When a function name (@pxref{M-x,, Running Commands by Name}),
+variable name (@pxref{Variables}), or face name (@pxref{Faces})
+appears in the documentation, it normally appears inside paired
+single-quotes. To view the documentation of that command, variable or
+face, you can click on the name with @kbd{Mouse-1} or @kbd{Mouse-2},
+or move point there and type @key{RET}. Use @kbd{C-c C-b} to retrace
+your steps.
+
+@cindex URL, viewing in help
+@cindex help, viewing web pages
+@cindex viewing web pages in help
+@cindex web pages, viewing in help
+@findex browse-url
+ You can follow cross references to URLs (web pages) also. This uses
+the @code{browse-url} command to view the page in the browser you
+choose. @xref{Browse-URL}.
+
+@kindex @key{TAB} @r{(Help mode)}
+@findex help-next-ref
+@kindex S-@key{TAB} @r{(Help mode)}
+@findex help-previous-ref
+ There are convenient commands to move point to cross references in
+the help text. @key{TAB} (@code{help-next-ref}) moves point down to
+the next cross reference. @kbd{S-@key{TAB}} moves up to the previous
+cross reference (@code{help-previous-ref}).
+
+ To view all documentation about any symbol name that appears in the
+text, move point to the symbol name and type @kbd{C-c C-c}
+(@code{help-follow-symbol}). This shows all available documentation
+about the symbol as a variable, function and/or face. As above, use
+@kbd{C-c C-b} to retrace your steps.
+
+@node Misc Help
+@section Other Help Commands
+
+@kindex C-h i
+@findex info
+@cindex Info
+@cindex manuals, on-line
+@cindex on-line manuals
+ @kbd{C-h i} (@code{info}) runs the Info program, which browses
+structured documentation files. The entire Emacs manual is available
+within Info, along with many other manuals for the GNU system. Type
+@kbd{h} after entering Info to run a tutorial on using Info.
+
+@cindex find Info manual by its file name
+ With a numeric argument @var{n}, @kbd{C-h i} selects the Info buffer
+@samp{*info*<@var{n}>}. This is useful if you want to browse multiple
+Info manuals simultaneously. If you specify just @kbd{C-u} as the
+prefix argument, @kbd{C-h i} prompts for the name of a documentation
+file, so you can browse a file which doesn't have an entry in the
+top-level Info menu.
+
+ The help commands @kbd{C-h F @var{function} @key{RET}} and @kbd{C-h
+K @var{key}}, described above, enter Info and go straight to the
+documentation of @var{function} or @var{key}.
+
+@kindex C-h S
+@findex info-lookup-symbol
+ When editing a program, if you have an Info version of the manual
+for the programming language, you can use @kbd{C-h S}
+(@code{info-lookup-symbol}) to find symbol (keyword, function or
+variable) in the proper manual. The details of how this command works
+depend on the major mode.
+
+@kindex C-h l
+@findex view-lossage
+ If something surprising happens, and you are not sure what you
+typed, use @kbd{C-h l} (@code{view-lossage}). @kbd{C-h l} displays
+the last 100 characters you typed in Emacs. If you see commands that
+you don't know, you can use @kbd{C-h c} to find out what they do.
+
+@kindex C-h e
+@findex view-echo-area-messages
+ To review recent echo area messages, use @kbd{C-h e}
+(@code{view-echo-area-messages}). This displays the buffer
+@code{*Messages*}, where those messages are kept.
+
+@kindex C-h m
+@findex describe-mode
+ Each Emacs major mode typically redefines a few keys and makes other
+changes in how editing works. @kbd{C-h m} (@code{describe-mode})
+displays documentation on the current major mode, which normally
+describes the commands and features that are changed in this mode.
+
+@kindex C-h b
+@findex describe-bindings
+ @kbd{C-h b} (@code{describe-bindings}) and @kbd{C-h s}
+(@code{describe-syntax}) show other information about the current
+environment within Emacs. @kbd{C-h b} displays a list of all the key
+bindings now in effect: first the local bindings of the current minor
+modes, then the local bindings defined by the current major mode, and
+finally the global bindings (@pxref{Key Bindings}). @kbd{C-h s}
+displays the contents of the syntax table, with explanations of each
+character's syntax (@pxref{Syntax}).
+
+ You can get a list of subcommands for a particular prefix key by
+typing @kbd{C-h} after the prefix key. (There are a few prefix keys
+for which this does not work---those that provide their own bindings
+for @kbd{C-h}. One of these is @key{ESC}, because @kbd{@key{ESC} C-h}
+is actually @kbd{C-M-h}, which marks a defun.)
+
+@node Help Files
+@section Help Files
+
+ The Emacs help commands described above display dynamic help based
+on the current state within Emacs, or refer to manuals. Other help
+commands display pre-written, static help files. These commands all

+ When a region of text is ``active,'' so that you can select it with
+the mouse or a key like @kbd{RET}, it often has associated help text.
+For instance, most parts of the mode line have help text. On
+graphical displays, the help text is displayed as a ``tooltip''
+(sometimes known as ``balloon help''), when you move the mouse over
+the active text. @xref{Tooltips}. On some systems, it is shown in
+the echo area. On text-only terminals, if Emacs cannot follow the
+mouse, it cannot show the help text on mouse-over.
+
+@kindex C-h .
+@findex display-local-help
+@vindex help-at-pt-display-when-idle
+ You can also access text region help info using the keyboard. The
+command @kbd{C-h .} (@code{display-local-help}) displays any help text
+associated with the text at point, using the echo area. If you want
+help text to be displayed automatically whenever it is available at
+point, set the variable @code{help-at-pt-display-when-idle} to
+@code{t}.
