The +@samp{s} command prompts you for a string in the echo area, and then +searches the remainder of the info file for an occurrence of that string. +If the string is found, the node containing it is selected, and the +cursor is left positioned at the start of the found string. Subsequent +@samp{s} commands show you the default search string within @samp{[} and +@samp{]}; pressing @key{RET} instead of typing a new string will use the +default search string. + +@dfn{Incremental searching} is similar to basic searching, but the +string is looked up while you are typing it, instead of waiting until +the entire search string has been specified. + +@node Xref Commands +@chapter Selecting Cross References + +We have already discussed the @samp{Next}, @samp{Prev}, and @samp{Up} +pointers which appear at the top of a node. In addition to these +pointers, a node may contain other pointers which refer you to a +different node, perhaps in another info file. Such pointers are called +@dfn{cross references}, or @dfn{xrefs} for short. + +@menu +* Parts of an Xref:: What a cross reference is made of. +* Selecting Xrefs:: Commands for selecting menu or note items. +@end menu + +@node Parts of an Xref +@section Parts of an Xref + +Cross references have two major parts: the first part is called the +@dfn{label}; it is the name that you can use to refer to the cross +reference, and the second is the @dfn{target}; it is the full name of +the node that the cross reference points to. + +The target is separated from the label by a colon @samp{:}; first the +label appears, and then the target. For example, in the sample menu +cross reference below, the single colon separates the label from the +target. + +@example +* Foo Label: Foo Target. More information about Foo. +@end example + +Note the @samp{.} which ends the name of the target. The @samp{.} is +not part of the target; it serves only to let Info know where the target +name ends. + +A shorthand way of specifying references allows two adjacent colons to +stand for a target name which is the same as the label name: + +@example +* Foo Commands:: Commands pertaining to Foo. +@end example + +In the above example, the name of the target is the same as the name of +the label, in this case @code{Foo Commands}. + +You will normally see two types of cross references while viewing nodes: +@dfn{menu} references, and @dfn{note} references. Menu references +appear within a node's menu; they begin with a @samp{*} at the beginning +of a line, and continue with a label, a target, and a comment which +describes what the contents of the node pointed to contains. + +Note references appear within the body of the node text; they begin with +@code{*Note}, and continue with a label and a target. + +Like @samp{Next}, @samp{Prev} and @samp{Up} pointers, cross references +can point to any valid node. They are used to refer you to a place +where more detailed information can be found on a particular subject. +Here is a cross reference which points to a node within the Texinfo +documentation: @xref{xref, , Writing an Xref, texinfo, the Texinfo +Manual}, for more information on creating your own texinfo cross +references. + +@node Selecting Xrefs +@section Selecting Xrefs + +The following table lists the Info commands which operate on menu items. + +@table @asis +@item @code{1} (@code{menu-digit}) +@itemx @code{2} @dots{} @code{9} +@cindex 1 @dots{} 9, in Info windows +@kindex 1 @dots{} 9, in Info windows +@findex menu-digit +Within an Info window, pressing a single digit, (such as @samp{1}), +selects that menu item, and places its node in the current window. +For convenience, there is one exception; pressing @samp{0} selects the +@emph{last} item in the node's menu. + +@item @code{0} (@code{last-menu-item}) +@kindex 0, in Info windows +@findex last-menu-item +Select the last item in the current node's menu. + +@item @code{m} (@code{menu-item}) +@kindex m +@findex menu-item +Reads the name of a menu item in the echo area and selects its node. +Completion is available while reading the menu label. + +@item @code{M-x find-menu} +@findex find-menu +Moves the cursor to the start of this node's menu. +@end table + +This table lists the Info commands which operate on note cross references. + +@table @asis +@item @code{f} (@code{xref-item}) +@itemx @code{r} +@kindex f +@kindex r +@findex xref-item +Reads the name of a note cross reference in the echo area and selects +its node.

If a variable does @emph{not} supply multiple choices to +complete over, it expects a numeric value. + +@item @code{M-x describe-variable} +@cindex variables, describing +@findex describe-variable +Reads the name of a variable in the echo area and then displays a brief +description of what the variable affects. +@end table + +Here is a list of the variables that you can set in Info. + +@table @code +@item automatic-footnotes +@vindex automatic-footnotes +When set to @code{On}, footnotes appear and disappear automatically. +This variable is @code{On} by default. When a node is selected, a +window containing the footnotes which appear in that node is created, +and the footnotes are displayed within the new window. The window that +Info creates to contain the footnotes is called @samp{*Footnotes*}. If +a node is selected which contains no footnotes, and a @samp{*Footnotes*} +window is on the screen, the @samp{*Footnotes*} window is deleted. +Footnote windows created in this fashion are not automatically tiled so +that they can use as little of the display as is possible. + +@item automatic-tiling +@vindex automatic-tiling +When set to @code{On}, creating or deleting a window resizes other +windows. This variable is @code{Off} by default. Normally, typing +@samp{C-x 2} divides the current window into two equal parts. When +@code{automatic-tiling} is set to @code{On}, all of the windows are +resized automatically, keeping an equal number of lines visible in each +window. There are exceptions to the automatic tiling; specifically, the +windows @samp{*Completions*} and @samp{*Footnotes*} are @emph{not} +resized through automatic tiling; they remain their original size. + +@item visible-bell +@vindex visible-bell +When set to @code{On}, GNU Info attempts to flash the screen instead of +ringing the bell. This variable is @code{Off} by default. Of course, +Info can only flash the screen if the terminal allows it; in the case +that the terminal does not allow it, the setting of this variable has no +effect. However, you can make Info perform quietly by setting the +@code{errors-ring-bell} variable to @code{Off}. + +@item errors-ring-bell +@vindex errors-ring-bell +When set to @code{On}, errors cause the bell to ring. The default +setting of this variable is @code{On}. + +@item gc-compressed-files +@vindex gc-compressed-files +When set to @code{On}, Info garbage collects files which had to be +uncompressed. The default value of this variable is @code{Off}. +Whenever a node is visited in Info, the info file containing that node +is read into core, and Info reads information about the tags and nodes +contained in that file. Once the tags information is read by Info, it +is never forgotten. However, the actual text of the nodes does not need +to remain in core unless a particular info window needs it. For +non-compressed files, the text of the nodes does not remain in core when +it is no longer in use. But de-compressing a file can be a time +consuming operation, and so Info tries hard not to do it twice. +@code{gc-compressed-files} tells Info it is okay to garbage collect the +text of the nodes of a file which was compressed on disk. + +@item show-index-match +@vindex show-index-match +When set to @code{On}, the portion of the matched search string is +highlighted in the message which explains where the matched search +string was found. The default value of this variable is @code{On}. +When Info displays the location where an index match was found, +(@pxref{Searching Commands, , @code{next-index-match}}), the portion of the +string that you had typed is highlighted by displaying it in the inverse +case from its surrounding characters. + +@item scroll-behaviour +@vindex scroll-behaviour +Controls what happens when forward scrolling is requested at the end of +a node, or when backward scrolling is requested at the beginning of a +node. The default value for this variable is @code{Continuous}. There +are three possible values for this variable: + +@table @code +@item Continuous +Tries to get the first item in this node's menu, or failing that, the +@samp{Next} node, or failing that, the @samp{Next} of the @samp{Up}. +This behaviour is identical to using the @samp{]} +(@code{global-next-node}) and @samp{[} (@code{global-prev-node}) +commands. + +@item Next Only +Only tries to get the @samp{Next} node. + +@item Page Only +Simply gives up, changing nothing.

Usually +the scrolling is done so as to put the cursor on the center line of the +current window. However, if the variable @code{scroll-step} has a +nonzero value, Info attempts to scroll the node text by that many lines; +if that is enough to bring the cursor back into the window, that is what +is done. The default value of this variable is 0, thus placing the +cursor (and the text it is attached to) in the center of the window. +Setting this variable to 1 causes a kind of "smooth scrolling" which +some people prefer. + +@item ISO-Latin +@cindex ISO Latin-1 characters +@vindex ISO-Latin +When set to @code{On}, Info accepts and displays ISO Latin-1 characters. +By default, Info assumes an ASCII character set. @code{ISO-Latin} tells +Info that it is running in an environment where the European standard +character set is in use, and allows you to input such characters to +Info, as well as display them. +@end table + +@c The following node and its children are currently unfinished.

This node's topic is ``how to use Info''. + + The top line of a node is its @dfn{header}. This node's header (look at +it now) says that it is the node named @samp{Help} in the file +@file{info}. It says that the @samp{Next} node after this one is the node +called @samp{Help-P}. An advanced Info command lets you go to any node +whose name you know. + + Besides a @samp{Next}, a node can have a @samp{Previous} or an +@samp{Up}. This node has a @samp{Previous} which is +@samp{Help-Small-Screen}, and an @samp{Up} which is @samp{Getting +Started}.

Things will get more complicated soon. Also, +do not try a new command until you are told it is time to. Otherwise, +you may make Info skip past an important warning that was coming up. + +@format +>> Now do an @kbd{n} to get to the node @samp{Help-^L} and learn more. +@end format + +@node Help-^L, Help-M, Help-P, Getting Started +@comment node-name, next, previous, up +@section The Space, Delete, B and ^L commands. + + This node's header tells you that you are now at node @samp{Help-^L}, and +that @kbd{p} would get you back to @samp{Help-P}. The node's title is +underlined; it says what the node is about (most nodes have titles). + + This is a big node and it does not all fit on your display screen. +You can tell that there is more that is not visible because you +can see the string @samp{--Top-----} rather than @samp{--All----} near +the bottom right corner of the screen. + + The Space, Delete and @kbd{B} commands exist to allow you to ``move +around'' in a node that does not all fit on the screen at once. +Space moves forward, to show what was below the bottom of the screen. +Delete moves backward, to show what was above the top of the screen +(there is not anything above the top until you have typed some spaces). + +@format +>> Now try typing a Space (afterward, type a Delete to return here). +@end format + + When you type the space, the two lines that were at the bottom of +the screen appear at the top, followed by more lines. Delete takes +the two lines from the top and moves them to the bottom, +@emph{usually}, but if there are not a full screen's worth of lines +above them they may not make it all the way to the bottom. + + Space and Delete scroll through all the nodes in an Info file as a +single logical sequence. In this sequence, a node's subnodes appear +following their parent. If a node's menu is on the screen, Space takes +you into the subnodes listed in the menu, one by one. Once you reach +the end of a node, Space takes you to the next node or back to the +parent node. + + If your screen is ever garbaged, you can tell Info to print it out +again by typing @kbd{C-l} (@kbd{Control-L}, that is---hold down ``Control'' and +type an @key{L} or @kbd{l}). + +@format +>> Type @kbd{C-l} now. +@end format + + To move back to the beginning of the node you are on, you can type +a lot of Deletes. You can also type simply @kbd{b} for beginning. +@format +>> Try that now. (We have put in enough verbiage to push this past +the first screenful, but screens are so big nowadays that perhaps it +isn't enough. You may need to shrink your Emacs or Info window.) +Then come back, with Spaces. +@end format + +If your screen is very tall, all of this node might fit at once. +In that case, "b" won't do anything. Sorry; what can we do? + + You have just learned a considerable number of commands. If you +want to use one but have trouble remembering which, you should type +a @key{?} which prints out a brief list of commands. When you are +finished looking at the list, make it go away by typing a @key{SPC}. + +@format +>> Type a @key{?} now. After it finishes, type a @key{SPC}. +@end format + + (If you are using the standalone Info reader, type `l' to return here.) + + From now on, you will encounter large nodes without warning, and +will be expected to know how to use Space and Delete to move +around in them without being told. Since not all terminals have +the same size screen, it would be impossible to warn you anyway. + +@format +>> Now type @kbd{n} to see the description of the @kbd{m} command. +@end format + +@node Help-M, Help-Adv, Help-^L, Getting Started +@comment node-name, next, previous, up +@section Menus + +Menus and the @kbd{m} command + + With only the @kbd{n} and @kbd{p} commands for moving between nodes, nodes +are restricted to a linear sequence. Menus allow a branching +structure. A menu is a list of other nodes you can move to. It is +actually just part of the text of the node formatted specially so that +Info can interpret it. The beginning of a menu is always identified +by a line which starts with @samp{* Menu:}. A node contains a menu if and +only if it has a line in it which starts that way. The only menu you +can use at any moment is the one in the node you are in. To use a +menu in any other node, you must move to that node first. + + After the start of the menu, each line that starts with a @samp{*} +identifies one subtopic. The line usually contains a brief name +for the subtopic (followed by a @samp{:}), the name of the node that talks +about that subtopic, and optionally some further description of the +subtopic. Lines in the menu that do not start with a @samp{*} have no +special meaning---they are only for the human reader's benefit and do +not define additional subtopics. Here is an example: + +@example +* Foo: FOO's Node This tells about FOO +@end example + +The subtopic name is Foo, and the node describing it is @samp{FOO's Node}. +The rest of the line is just for the reader's Information. +[[ But this line is not a real menu item, simply because there is +no line above it which starts with @samp{* Menu:}.]] + + When you use a menu to go to another node (in a way that will be +described soon), what you specify is the subtopic name, the first +thing in the menu line. Info uses it to find the menu line, extracts +the node name from it, and goes to that node. The reason that there +is both a subtopic name and a node name is that the node name must be +meaningful to the computer and may therefore have to be ugly looking. +The subtopic name can be chosen just to be convenient for the user to +specify. Often the node name is convenient for the user to specify +and so both it and the subtopic name are the same. There is an +abbreviation for this: + +@example +* Foo:: This tells about FOO +@end example + +@noindent +This means that the subtopic name and node name are the same; they are +both @samp{Foo}. + +@format +>> Now use Spaces to find the menu in this node, then come back to + the front with a @kbd{b} and some Spaces. As you see, a menu is + actually visible in its node. If you cannot find a menu in a node + by looking at it, then the node does not have a menu and the + @kbd{m} command is not available. +@end format + + The command to go to one of the subnodes is @kbd{m}---but @emph{do +not do it yet!} Before you use @kbd{m}, you must understand the +difference between commands and arguments. So far, you have learned +several commands that do not need arguments. When you type one, Info +processes it and is instantly ready for another command. The @kbd{m} +command is different: it is incomplete without the @dfn{name of the +subtopic}. Once you have typed @kbd{m}, Info tries to read the +subtopic name. + + Now look for the line containing many dashes near the bottom of the +screen. There is one more line beneath that one, but usually it is +blank. If it is empty, Info is ready for a command, such as @kbd{n} +or @kbd{b} or Space or @kbd{m}. If that line contains text ending +in a colon, it mean Info is trying to read the @dfn{argument} to a +command. At such times, commands do not work, because Info tries to +use them as the argument. You must either type the argument and +finish the command you started, or type @kbd{Control-g} to cancel the +command. When you have done one of those things, the line becomes +blank again. + + The command to go to a subnode via a menu is @kbd{m}. After you type +the @kbd{m}, the line at the bottom of the screen says @samp{Menu item: }. +You must then type the name of the subtopic you want, and end it with +a @key{RET}. + + You can abbreviate the subtopic name. If the abbreviation is not +unique, the first matching subtopic is chosen. Some menus put the +shortest possible abbreviation for each subtopic name in capital +letters, so you can see how much you need to type. It does not matter +whether you use upper case or lower case when you type the subtopic. Do +not put spaces at the end of the subtopic name; in the middle of the +subtopic name, use one space (no more!) wherever the menu item name has +a space. + + You can also use the @dfn{completion} feature to help enter the subtopic +name. If you type the Tab key after entering part of a name, it will +magically fill in more of the name---as much as follows uniquely from +what you have entered. + + If you move the cursor to one of the menu subtopic lines, then you do +not need to type the argument: you just type a Return, and it stands for +the subtopic of the line you are on. + +Here is a menu to give you a chance to practice. + +@menu +This menu gives you three ways of going to one place, Help-FOO. + +* Foo: Help-FOO. A node you can visit for fun. +* Bar: Help-FOO. Strange! two ways to get to the same place. +* Help-FOO:: And yet another! +@end menu + +@format +>> Now type just an @kbd{m} and see what happens: +@end format + + Now you are ``inside'' an @kbd{m} command. Commands cannot be used +now; the next thing you will type must be the name of a subtopic. + + You can change your mind about doing the @kbd{m} by typing Control-g. + +@format +>> Try that now; notice the bottom line clear. + +>> Then type another @kbd{m}. + +>> Now type @samp{BAR} item name. Do not type Return yet. +@end format + + While you are typing the item name, you can use the Delete key to +cancel one character at a time if you make a mistake. + +@format +>> Type one to cancel the @samp{R}.

This is the usual +convention---the nodes you reach from a menu have @samp{Up} nodes that lead +back to the menu. Menus move Down in the tree, and @samp{Up} moves Up. +@samp{Previous}, on the other hand, is usually used to ``stay on the same +level but go backwards'' + + You can go back to the node @samp{Help-M} by typing the command +@kbd{u} for ``Up''.

As you move from node to node, Info +records the nodes where you have been in a special history list. The +@kbd{l} command revisits nodes in the history list; each successive +@kbd{l} command moves one step back through the history. + + If you have been following directions, an @kbd{l} command now will get +you back to @samp{Help-M}.

You type +@kbd{s} followed by the string to search for, terminated by @key{RET}. +To search for the same string again, just @kbd{s} followed by @key{RET} +will do. The file's nodes are scanned in the order they are in in the +file, which has no necessary relationship to the order that they may be +in in the tree structure of menus and @samp{next} pointers. But +normally the two orders are not very different. In any case, you can +always do a @kbd{b} to find out what node you have reached, if the +header is not visible (this can happen, because @kbd{s} puts your cursor +at the occurrence of the string, not at the beginning of the node). + +@kbd{Meta-s} is equivalent to @kbd{s}. That is for compatibility with +other GNU packages that use @kbd{M-s} for a similar kind of search +command. + +If you grudge the system each character of type-in it requires, you +might like to use the commands @kbd{1}, @kbd{2}, @kbd{3}, @kbd{4}, ... +@kbd{9}. They are short for the @kbd{m} command together with an +argument. @kbd{1} goes through the first item in the current node's +menu; @kbd{2} goes through the second item, etc. + +If your display supports multiple fonts, and you are using Emacs' Info +mode to read Info files, the @samp{*} for the fifth menu item is +underlined, and so is the @samp{*} for the ninth item; these underlines +make it easy to see at a glance which number to use for an item. + +On ordinary terminals, you won't have underlining. If you need to +actually count items, it is better to use @kbd{m} instead, and specify +the name. + +The Info command @kbd{e} changes from Info mode to an ordinary +Emacs editing mode, so that you can edit the text of the current node. +Type @kbd{C-c C-c} to switch back to Info. The @kbd{e} command is allowed +only if the variable @code{Info-enable-edit} is non-@code{nil}. + +@node Add, Menus, Expert, Advanced Info +@comment node-name, next, previous, up +@section Adding a new node to Info + +To add a new topic to the list in the Info directory, you must: +@enumerate +@item +Create some nodes, in some file, to document that topic. +@item +Put that topic in the menu in the directory. @xref{Menus, Menu}. +@end enumerate + +Usually, the way to create the nodes is with Texinfo @pxref{Top,, Overview of +Texinfo, texinfo, Texinfo: The GNU Documentation Format}); this has the +advantage that you can also make a printed manual from them. However, +if you want to edit an Info file, here is how. + + The new node can live in an existing documentation file, or in a new +one. It must have a @key{^_} character before it (invisible to the +user; this node has one but you cannot see it), and it ends with either +a @key{^_}, a @key{^L}, or the end of file. Note: If you put in a +@key{^L} to end a new node, be sure that there is a @key{^_} after it +to start the next one, since @key{^L} cannot @emph{start} a node. +Also, a nicer way to make a node boundary be a page boundary as well +is to put a @key{^L} @emph{right after} the @key{^_}. + + The @key{^_} starting a node must be followed by a newline or a +@key{^L} newline, after which comes the node's header line. The +header line must give the node's name (by which Info finds it), +and state the names of the @samp{Next}, @samp{Previous}, and @samp{Up} nodes (if +there are any). As you can see, this node's @samp{Up} node is the node +@samp{Top}, which points at all the documentation for Info. The @samp{Next} +node is @samp{Menus}. + + The keywords @dfn{Node}, @dfn{Previous}, @dfn{Up}, and @dfn{Next}, +may appear in any order, anywhere in the header line, but the +recommended order is the one in this sentence. Each keyword must be +followed by a colon, spaces and tabs, and then the appropriate name. +The name may be terminated with a tab, a comma, or a newline. A space +does not end it; node names may contain spaces. The case of letters +in the names is insignificant. + + A node name has two forms. A node in the current file is named by +what appears after the @samp{Node: } in that node's first line. For +example, this node's name is @samp{Add}. A node in another file is +named by @samp{(@var{filename})@var{node-within-file}}, as in +@samp{(info)Add} for this node. If the file name starts with ``./'', +then it is relative to the current directory; otherwise, it is relative +starting from the standard Info file directory of your site. +The name @samp{(@var{filename})Top} can be abbreviated to just +@samp{(@var{filename})}. By convention, the name @samp{Top} is used for +the ``highest'' node in any single file---the node whose @samp{Up} points +out of the file. The Directory node is @file{(dir)}. The @samp{Top} node +of a document file listed in the Directory should have an @samp{Up: +(dir)} in it. + + The node name @kbd{*} is special: it refers to the entire file. +Thus, @kbd{g*} shows you the whole current file. The use of the +node @kbd{*} is to make it possible to make old-fashioned, +unstructured files into nodes of the tree. + + The @samp{Node:} name, in which a node states its own name, must not +contain a filename, since Info when searching for a node does not +expect one to be there. The @samp{Next}, @samp{Previous} and @samp{Up} names may +contain them. In this node, since the @samp{Up} node is in the same file, +it was not necessary to use one. + + Note that the nodes in this file have a file name in the header +line. The file names are ignored by Info, but they serve as comments +to help identify the node for the user. + +@node Menus, Cross-refs, Add, Advanced Info +@comment node-name, next, previous, up +@section How to Create Menus + + Any node in the Info hierarchy may have a @dfn{menu}---a list of subnodes. +The @kbd{m} command searches the current node's menu for the topic which it +reads from the terminal. + + A menu begins with a line starting with @samp{* Menu:}. The rest of the +line is a comment. After the starting line, every line that begins +with a @samp{* } lists a single topic. The name of the topic--the +argument that the user must give to the @kbd{m} command to select this +topic---comes right after the star and space, and is followed by a +colon, spaces and tabs, and the name of the node which discusses that +topic. The node name, like node names following @samp{Next}, @samp{Previous} +and @samp{Up}, may be terminated with a tab, comma, or newline; it may also +be terminated with a period. + + If the node name and topic name are the same, then rather than +giving the name twice, the abbreviation @samp{* NAME::} may be used +(and should be used, whenever possible, as it reduces the visual +clutter in the menu). + + It is considerate to choose the topic names so that they differ +from each other very near the beginning---this allows the user to type +short abbreviations. In a long menu, it is a good idea to capitalize +the beginning of each item name which is the minimum acceptable +abbreviation for it (a long menu is more than 5 or so entries). + + The nodes listed in a node's menu are called its ``subnodes'', and +it is their ``superior''. They should each have an @samp{Up:} pointing at +the superior. It is often useful to arrange all or most of the +subnodes in a sequence of @samp{Next} and @samp{Previous} pointers so that someone who +wants to see them all need not keep revisiting the Menu. + + The Info Directory is simply the menu of the node @samp{(dir)Top}---that +is, node @samp{Top} in file @file{.../info/dir}. You can put new entries +in that menu just like any other menu. The Info Directory is @emph{not} the +same as the file directory called @file{info}. It happens that many of +Info's files live on that file directory, but they do not have to; and +files on that directory are not automatically listed in the Info +Directory node. + + Also, although the Info node graph is claimed to be a ``hierarchy'', +in fact it can be @emph{any} directed graph. Shared structures and +pointer cycles are perfectly possible, and can be used if they are +appropriate to the meaning to be expressed. There is no need for all +the nodes in a file to form a connected structure. In fact, this file +has two connected components. You are in one of them, which is under +the node @samp{Top}; the other contains the node @samp{Help} which the +@kbd{h} command goes to. In fact, since there is no garbage +collector, nothing terrible happens if a substructure is not pointed +to, but such a substructure is rather useless since nobody can +ever find out that it exists. + +@node Cross-refs, Tags, Menus, Advanced Info +@comment node-name, next, previous, up +@section Creating Cross References + + A cross reference can be placed anywhere in the text, unlike a menu +item which must go at the front of a line. A cross reference looks +like a menu item except that it has @samp{*note} instead of @kbd{*}. +It @emph{cannot} be terminated by a @samp{)}, because @samp{)}'s are +so often part of node names. If you wish to enclose a cross reference +in parentheses, terminate it with a period first. Here are two +examples of cross references pointers: + +@example +*Note details: commands. (See *note 3: Full Proof.) +@end example + +They are just examples. The places they ``lead to'' do not really exist! + +@node Tags, Checking, Cross-refs, Advanced Info +@comment node-name, next, previous, up +@section Tags Tables for Info Files + + You can speed up the access to nodes of a large Info file by giving +it a tags table. Unlike the tags table for a program, the tags table for +an Info file lives inside the file itself and is used +automatically whenever Info reads in the file. + + To make a tags table, go to a node in the file using Emacs Info mode and type +@kbd{M-x Info-tagify}. Then you must use @kbd{C-x C-s} to save the +file. + + Once the Info file has a tags table, you must make certain it is up +to date. If, as a result of deletion of text, any node moves back +more than a thousand characters in the file from the position +recorded in the tags table, Info will no longer be able to find that +node. To update the tags table, use the @code{Info-tagify} command again. + + An Info file tags table appears at the end of the file and looks like +this: + +@example +^_ +Tag Table: +File: info, Node: Cross-refs^?21419 +File: info, Node: Tags^?22145 +^_ +End Tag Table +@end example + +@noindent +Note that it contains one line per node, and this line contains +the beginning of the node's header (ending just after the node name), +a Delete character, and the character position in the file of the +beginning of the node. + +@node Checking, Emacs Info Variables, Tags, Advanced Info +@comment node-name, next, previous, up +@section Checking an Info File + + When creating an Info file, it is easy to forget the name of a node +when you are making a pointer to it from another node. If you put in +the wrong name for a node, this is not detected until someone +tries to go through the pointer using Info. Verification of the Info +file is an automatic process which checks all pointers to nodes and +reports any pointers which are invalid. Every @samp{Next}, @samp{Previous}, and +@samp{Up} is checked, as is every menu item and every cross reference. In +addition, any @samp{Next} which does not have a @samp{Previous} pointing back is +reported. Only pointers within the file are checked, because checking +pointers to other files would be terribly slow.
