Here -is a template showing an invocation of GNU Info from the shell: - - info [--OPTION-NAME OPTION-VALUE] MENU-ITEM... - -The following OPTION-NAMES are available when invoking Info from the -shell: - -`--directory DIRECTORY-PATH' -`-d DIRECTORY-PATH' - Add DIRECTORY-PATH to the list of directory paths searched when - Info needs to find a file. You may issue `--directory' multiple - times; once for each directory which contains Info files. - Alternatively, you may specify a value for the environment variable - `INFOPATH'; if `--directory' is not given, the value of `INFOPATH' - is used. The value of `INFOPATH' is a colon separated list of - directory names. If you do not supply `INFOPATH' or - `--directory-path', Info uses a default path. - -`--file FILENAME' -`-f FILENAME' - Specify a particular Info file to visit. By default, Info visits - the file `dir'; if you use this option, Info will start with - `(FILENAME)Top' as the first file and node. - -`--node NODENAME' -`-n NODENAME' - Specify a particular node to visit in the initial file that Info - loads. This is especially useful in conjunction with `--file'(1) - (*note Options-Footnotes::). You may specify `--node' multiple - times; for an interactive Info, each NODENAME is visited in its - own window, for a non-interactive Info (such as when `--output' is - given) each NODENAME is processed sequentially. - -`--output FILENAME' -`-o FILENAME' - Specify FILENAME as the name of a file to which to direct output. - Each node that Info visits will be output to FILENAME instead of - interactively viewed. A value of `-' for FILENAME specifies the - standard output. - -`--subnodes' - This option only has meaning when given in conjunction with - `--output'. It means to recursively output the nodes appearing in - the menus of each node being output. Menu items which resolve to - external Info files are not output, and neither are menu items - which are members of an index. Each node is only output once. - -`--help' -`-h' - Produces a relatively brief description of the available Info - options. - -`--version' - Prints the version information of Info and exits. - -`MENU-ITEM' - Info treats its remaining arguments as the names of menu items. - The first argument is a menu item in the initial node visited, - while the second argument is a menu item in the first argument's - node. You can easily move to the node of your choice by - specifying the menu names which describe the path to that node. - For example, - - info emacs buffers - - first selects the menu item `Emacs' in the node `(dir)Top', and - then selects the menu item `Buffers' in the node `(emacs)Top'. - - -File: info-stnd.info, Node: Options-Footnotes, Up: Options - -(1) Of course, you can specify both the file and node in a `--node' -command; but don't forget to escape the open and close parentheses from -the shell as in: `info --node '(emacs)Buffers'' - - -File: info-stnd.info, Node: Cursor Commands, Next: Scrolling Commands, Prev: Options, Up: Top - -Moving the Cursor -***************** - -Many people find that reading screens of text page by page is made -easier when one is able to indicate particular pieces of text with some -kind of pointing device. Since this is the case, GNU Info (both the -Emacs and standalone versions) have several commands which allow you to -move the cursor about the screen. The notation used in this manual to -describe keystrokes is identical to the notation used within the Emacs -manual, and the GNU Readline manual. *Note Character Conventions: -(emacs)Characters, if you are unfamiliar with the notation. - -The following table lists the basic cursor movement commands in Info. -Each entry consists of the key sequence you should type to execute the -cursor movement, the `M-x'(1) (*note Cursor Commands-Footnotes::) -command name (displayed in parentheses), and a short description of -what the command does. All of the cursor motion commands can take an -"numeric" argument (*note `universal-argument': Miscellaneous -Commands.), to find out how to supply them. With a numeric argument, -the motion commands are simply executed that many times; for example, a -numeric argument of 4 given to `next-line' causes the cursor to move -down 4 lines. With a negative numeric argument, the motion is -reversed; an argument of -4 given to the `next-line' command would -cause the cursor to move *up* 4 lines. - -`C-n' (`next-line') - Move the cursor down to the next line. - -`C-p' (`prev-line') - Move the cursor up to the previous line. - -`C-a' (`beginning-of-line') - Move the cursor to the start of the current line. - -`C-e' (`end-of-line') - Move the cursor to the end of the current line. - -`C-f' (`forward-char') - Move the cursor forward a character. - -`C-b' (`backward-char') - Move the cursor backward a character. - -`M-f' (`forward-word') - Move the cursor forward a word. - -`M-b' (`backward-word') - Move the cursor backward a word. - -`M-<' (`beginning-of-node') -`b' - Move the cursor to the start of the current node. - -`M->' (`end-of-node') - Move the cursor to the end of the current node. - -`M-r' (`move-to-window-line') - Move the cursor to a specific line of the window. Without a - numeric argument, `M-r' moves the cursor to the start of the line - in the center of the window. With a numeric argument of N, `M-r' - moves the cursor to the start of the Nth line in the window. - - -File: info-stnd.info, Node: Cursor Commands-Footnotes, Up: Cursor Commands - -(1) `M-x' is also a command; it invokes `execute-extended-command'. -*Note Executing an extended command: (emacs)M-x, for more detailed -information. - - -File: info-stnd.info, Node: Scrolling Commands, Next: Node Commands, Prev: Cursor Commands, Up: Top - -Moving Text Within a Window -*************************** - -Sometimes you are looking at a screenful of text, and only part of the -current paragraph you are reading is visible on the screen. The -commands detailed in this section are used to shift which part of the -current node is visible on the screen. - -`SPC' (`scroll-forward') -`C-v' - Shift the text in this window up. That is, show more of the node - which is currently below the bottom of the window. With a numeric - argument, show that many more lines at the bottom of the window; a - numeric argument of 4 would shift all of the text in the window up - 4 lines (discarding the top 4 lines), and show you four new lines - at the bottom of the window. Without a numeric argument, SPC - takes the bottom two lines of the window and places them at the - top of the window, redisplaying almost a completely new screenful - of lines. - -`DEL' (`scroll-backward') -`M-v' - Shift the text in this window down. The inverse of - `scroll-forward'. - -The `scroll-forward' and `scroll-backward' commands can also move -forward and backward through the node structure of the file. If you -press SPC while viewing the end of a node, or DEL while viewing the -beginning of a node, what happens is controlled by the variable -`scroll-behavior'. *Note `scroll-behavior': Variables, for more -information. - -`C-l' (`redraw-display') - Redraw the display from scratch, or shift the line containing the - cursor to a specified location. With no numeric argument, `C-l' - clears the screen, and then redraws its entire contents. Given a - numeric argument of N, the line containing the cursor is shifted - so that it is on the Nth line of the window. - -`C-x w' (`toggle-wrap') - Toggles the state of line wrapping in the current window. - Normally, lines which are longer than the screen width "wrap", - i.e., they are continued on the next line. Lines which wrap have - a `\' appearing in the rightmost column of the screen. You can - cause such lines to be terminated at the rightmost column by - changing the state of line wrapping in the window with `C-x w'. - When a line which needs more space than one screen width to - display is displayed, a `$' appears in the rightmost column of the - screen, and the remainder of the line is invisible. - - -File: info-stnd.info, Node: Node Commands, Next: Searching Commands, Prev: Scrolling Commands, Up: Top - -Selecting a New Node -******************** - -This section details the numerous Info commands which select a new node -to view in the current window. - -The most basic node commands are `n', `p', `u', and `l'. - -When you are viewing a node, the top line of the node contains some Info -"pointers" which describe where the next, previous, and up nodes are. -Info uses this line to move about the node structure of the file when -you use the following commands: - -`n' (`next-node') - Select the `Next' node. - -`p' (`prev-node') - Select the `Prev' node. - -`u' (`up-node') - Select the `Up' node. - -You can easily select a node that you have already viewed in this window -by using the `l' command - this name stands for "last", and actually -moves through the list of already visited nodes for this window. `l' -with a negative numeric argument moves forward through the history of -nodes for this window, so you can quickly step between two adjacent (in -viewing history) nodes. - -`l' (`history-node') - Select the most recently selected node in this window. - -Two additional commands make it easy to select the most commonly -selected nodes; they are `t' and `d'. - -`t' (`top-node') - Select the node `Top' in the current Info file. - -`d' (`dir-node') - Select the directory node (i.e., the node `(dir)'). - -Here are some other commands which immediately result in the selection -of a different node in the current window: - -`<' (`first-node') - Selects the first node which appears in this file. This node is - most often `Top', but it does not have to be. - -`>' (`last-node') - Select the last node which appears in this file. - -`]' (`global-next-node') - Move forward or down through node structure. If the node that you - are currently viewing has a `Next' pointer, that node is selected. - Otherwise, if this node has a menu, the first menu item is - selected. If there is no `Next' and no menu, the same process is - tried with the `Up' node of this node. - -`[' (`global-prev-node') - Move backward or up through node structure. If the node that you - are currently viewing has a `Prev' pointer, that node is selected. - Otherwise, if the node has an `Up' pointer, that node is selected, - and if it has a menu, the last item in the menu is selected. - -You can get the same behavior as `global-next-node' and -`global-prev-node' while simply scrolling through the file with SPC and -DEL; *Note `scroll-behavior': Variables, for more information. - -`g' (`goto-node') - Read the name of a node and select it. No completion is done while - reading the node name, since the desired node may reside in a - separate file. The node must be typed exactly as it appears in - the Info file. A file name may be included as with any node - specification, for example - - `g(emacs)Buffers' - - finds the node `Buffers' in the Info file `emacs'. - -`C-x k' (`kill-node') - Kill a node. The node name is prompted for in the echo area, with - a default of the current node. "Killing" a node means that Info - tries hard to forget about it, removing it from the list of - history nodes kept for the window where that node is found. - Another node is selected in the window which contained the killed - node. - -`C-x C-f' (`view-file') - Read the name of a file and selects the entire file. The command - `C-x C-f FILENAME' - is equivalent to typing - `g(FILENAME)*' - -`C-x C-b' (`list-visited-nodes') - Make a window containing a menu of all of the currently visited - nodes. This window becomes the selected window, and you may use - the standard Info commands within it. - -`C-x b' (`select-visited-node') - Select a node which has been previously visited in a visible - window. This is similar to `C-x C-b' followed by `m', but no - window is created. - - -File: info-stnd.info, Node: Searching Commands, Next: Xref Commands, Prev: Node Commands, Up: Top - -Searching an Info File -********************** - -GNU Info allows you to search for a sequence of characters throughout an -entire Info file, search through the indices of an Info file, or find -areas within an Info file which discuss a particular topic. - -`s' (`search') - Read a string in the echo area and search for it. - -`C-s' (`isearch-forward') - Interactively search forward through the Info file for a string as - you type it. - -`C-r' (`isearch-backward') - Interactively search backward through the Info file for a string as - you type it. - -`i' (`index-search') - Look up a string in the indices for this Info file, and select a - node where the found index entry points to. - -`,' (`next-index-match') - Move to the node containing the next matching index item from the - last `i' command. - -The most basic searching command is `s' (`search'). The `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 `s' -commands show you the default search string within `[' and `]'; -pressing RET instead of typing a new string will use the default search -string. - -"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. - - -File: info-stnd.info, Node: Xref Commands, Next: Window Commands, Prev: Searching Commands, Up: Top - -Selecting Cross References -************************** - -We have already discussed the `Next', `Prev', and `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 "cross references", or -"xrefs" for short. - -* Menu: - -* Parts of an Xref:: What a cross reference is made of. -* Selecting Xrefs:: Commands for selecting menu or note items. - - -File: info-stnd.info, Node: Parts of an Xref, Next: Selecting Xrefs, Up: Xref Commands - -Parts of an Xref -================ - -Cross references have two major parts: the first part is called the -"label"; it is the name that you can use to refer to the cross -reference, and the second is the "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 `:'; 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. - - * Foo Label: Foo Target. More information about Foo. - -Note the `.' which ends the name of the target. The `.' 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: - - * Foo Commands:: Commands pertaining to Foo. - -In the above example, the name of the target is the same as the name of -the label, in this case `Foo Commands'. - -You will normally see two types of cross reference while viewing nodes: -"menu" references, and "note" references. Menu references appear -within a node's menu; they begin with a `*' 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 -`*Note', and continue with a label and a target. - -Like `Next', `Prev', and `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: *Note Writing an Xref: (texinfo)xref, for more -information on creating your own texinfo cross references. - - -File: info-stnd.info, Node: Selecting Xrefs, Prev: Parts of an Xref, Up: Xref Commands - -Selecting Xrefs -=============== - -The following table lists the Info commands which operate on menu items. - -`1' (`menu-digit') -`2' ... `9' - Within an Info window, pressing a single digit, (such as `1'), - selects that menu item, and places its node in the current window. - For convenience, there is one exception; pressing `0' selects the - *last* item in the node's menu. - -`0' (`last-menu-item') - Select the last item in the current node's menu. - -`m' (`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. - -`M-x find-menu' - Move the cursor to the start of this node's menu. - -This table lists the Info commands which operate on note cross -references. - -`f' (`xref-item') -`r' - Reads the name of a note cross reference in the echo area and - selects its node. Completion is available while reading the cross - reference label. - -Finally, the next few commands operate on menu or note references alike: - -`TAB' (`move-to-next-xref') - Move the cursor to the start of the next nearest menu item or note - reference in this node. You can then use RET - (`select-reference-this-line') to select the menu or note - reference. - -`M-TAB' (`move-to-prev-xref') - Move the cursor the start of the nearest previous menu item or note - reference in this node. - -`RET' (`select-reference-this-line') - Select the menu item or note reference appearing on this line. - - -File: info-stnd.info, Node: Window Commands, Next: Printing Nodes, Prev: Xref Commands, Up: Top - -Manipulating Multiple Windows -***************************** - -A "window" is a place to show the text of a node. Windows have a view -area where the text of the node is displayed, and an associated "mode -line", which briefly describes the node being viewed. - -GNU Info supports multiple windows appearing in a single screen; each -window is separated from the next by its modeline. At any time, there -is only one "active" window, that is, the window in which the cursor -appears. There are commands available for creating windows, changing -the size of windows, selecting which window is active, and for deleting -windows. - -* Menu: - -* The Mode Line:: What appears in the mode line? -* Basic Windows:: Manipulating windows in Info. -* The Echo Area:: Used for displaying errors and reading input. - - -File: info-stnd.info, Node: The Mode Line, Next: Basic Windows, Up: Window Commands - -The Mode Line -============= - -A "mode line" is a line of inverse video which appears at the bottom of -an Info window. It describes the contents of the window just above it; -this information includes the name of the file and node appearing in -that window, the number of screen lines it takes to display the node, -and the percentage of text that is above the top of the window. It can -also tell you if the indirect tags table for this Info file needs to be -updated, and whether or not the Info file was compressed when stored on -disk. - -Here is a sample mode line for a window containing an uncompressed file -named `dir', showing the node `Top'. - - -----Info: (dir)Top, 40 lines --Top--------------------------------------- - ^^ ^ ^^^ ^^ - (file)Node #lines where - -When a node comes from a file which is compressed on disk, this is -indicated in the mode line with two small `z''s.

To allow -this, Info can display more than one "window". Each window has its own -mode line (*note The Mode Line::.) and history of nodes viewed in that -window (*note `history-node': Node Commands.). - -`C-x o' (`next-window') - Select the next window on the screen. Note that the echo area can - only be selected if it is already in use, and you have left it - temporarily. Normally, `C-x o' simply moves the cursor into the - next window on the screen, or if you are already within the last - window, into the first window on the screen. Given a numeric - argument, `C-x o' moves over that many windows. A negative - argument causes `C-x o' to select the previous window on the - screen. - -`M-x prev-window' - Select the previous window on the screen. This is identical to - `C-x o' with a negative argument. - -`C-x 2' (`split-window') - Split the current window into two windows, both showing the same - node. Each window is one half the size of the original window, - and the cursor remains in the original window. The variable - `automatic-tiling' can cause all of the windows on the screen to - be resized for you automatically, please *note automatic-tiling: - Variables. for more information. - -`C-x 0' (`delete-window') - Delete the current window from the screen. If you have made too - many windows and your screen appears cluttered, this is the way to - get rid of some of them. - -`C-x 1' (`keep-one-window') - Delete all of the windows excepting the current one. - -`ESC C-v' (`scroll-other-window') - Scroll the other window, in the same fashion that `C-v' might - scroll the current window. Given a negative argument, scroll the - "other" window backward. - -`C-x ^' (`grow-window') - Grow (or shrink) the current window. Given a numeric argument, - grow the current window that many lines; with a negative numeric - argument, shrink the window instead. - -`C-x t' (`tile-windows') - Divide the available screen space among all of the visible windows. - Each window is given an equal portion of the screen in which to - display its contents. The variable `automatic-tiling' can cause - `tile-windows' to be called when a window is created or deleted. - *Note `automatic-tiling': Variables. - - -File: info-stnd.info, Node: The Echo Area, Prev: Basic Windows, Up: Window Commands - -The Echo Area -============= - -The "echo area" is a one line window which appears at the bottom of the -screen. It is used to display informative or error messages, and to -read lines of input from you when that is necessary. Almost all of the -commands available in the echo area are identical to their Emacs -counterparts, so please refer to that documentation for greater depth of -discussion on the concepts of editing a line of text. The following -table briefly lists the commands that are available while input is being -read in the echo area: - -`C-f' (`echo-area-forward') - Move forward a character. - -`C-b' (`echo-area-backward') - Move backward a character. - -`C-a' (`echo-area-beg-of-line') - Move to the start of the input line. - -`C-e' (`echo-area-end-of-line') - Move to the end of the input line. - -`M-f' (`echo-area-forward-word') - Move forward a word. - -`M-b' (`echo-area-backward-word') - Move backward a word. - -`C-d' (`echo-area-delete') - Delete the character under the cursor. - -`DEL' (`echo-area-rubout') - Delete the character behind the cursor. - -`C-g' (`echo-area-abort') - Cancel or quit the current operation. If completion is being read, - `C-g' discards the text of the input line which does not match any - completion. If the input line is empty, `C-g' aborts the calling - function. - -`RET' (`echo-area-newline') - Accept (or forces completion of) the current input line. - -`C-q' (`echo-area-quoted-insert') - Insert the next character verbatim. This is how you can insert - control characters into a search string, for example. - -PRINTING CHARACTER (`echo-area-insert') - Insert the character. - -`M-TAB' (`echo-area-tab-insert') - Insert a TAB character. - -`C-t' (`echo-area-transpose-chars') - Transpose the characters at the cursor. - -The next group of commands deal with "killing", and "yanking" text. -For an in depth discussion of killing and yanking, *note Killing and -Deleting: (emacs)Killing. - -`M-d' (`echo-area-kill-word') - Kill the word following the cursor. - -`M-DEL' (`echo-area-backward-kill-word') - Kill the word preceding the cursor. - -`C-k' (`echo-area-kill-line') - Kill the text from the cursor to the end of the line. - -`C-x DEL' (`echo-area-backward-kill-line') - Kill the text from the cursor to the beginning of the line. - -`C-y' (`echo-area-yank') - Yank back the contents of the last kill. - -`M-y' (`echo-area-yank-pop') - Yank back a previous kill, removing the last yanked text first. - -Sometimes when reading input in the echo area, the command that needed -input will only accept one of a list of several choices. The choices -represent the "possible completions", and you must respond with one of -them. Since there are a limited number of responses you can make, Info -allows you to abbreviate what you type, only typing as much of the -response as is necessary to uniquely identify it. In addition, you can -request Info to fill in as much of the response as is possible; this is -called "completion". - -The following commands are available when completing in the echo area: - -`TAB' (`echo-area-complete') -`SPC' - Insert as much of a completion as is possible. - -`?' (`echo-area-possible-completions') - Display a window containing a list of the possible completions of - what you have typed so far. For example, if the available choices - are: - - bar - foliate - food - forget - - and you have typed an `f', followed by `?', the possible - completions would contain: - - foliate - food - forget - - i.e., all of the choices which begin with `f'. Pressing SPC or - TAB would result in `fo' appearing in the echo area, since all of - the choices which begin with `f' continue with `o'. Now, typing - `l' followed by `TAB' results in `foliate' appearing in the echo - area, since that is the only choice which begins with `fol'. - -`ESC C-v' (`echo-area-scroll-completions-window') - Scroll the completions window, if that is visible, or the "other" - window if not. - - -File: info-stnd.info, Node: Printing Nodes, Next: Miscellaneous Commands, Prev: Window Commands, Up: Top - -Printing Out Nodes -****************** - -You may wish to print out the contents of a node as a quick reference -document for later use.

If the variable does - not exist, the node is simply piped to `lpr'. - - -File: info-stnd.info, Node: Miscellaneous Commands, Next: Variables, Prev: Printing Nodes, Up: Top - -Miscellaneous Commands -********************** - -GNU Info contains several commands which self-document GNU Info: - -`M-x describe-command' - Read the name of an Info command in the echo area and then display - a brief description of what that command does. - -`M-x describe-key' - Read a key sequence in the echo area, and then display the name and - documentation of the Info command that the key sequence invokes. - -`M-x describe-variable' - Read the name of a variable in the echo area and then display a - brief description of what the variable affects. - -`M-x where-is' - Read the name of an Info command in the echo area, and then display - a key sequence which can be typed in order to invoke that command. - -`C-h' (`get-help-window') -`?' - Create (or Move into) the window displaying `*Help*', and place a - node containing a quick reference card into it. This window - displays the most concise information about GNU Info available. - -`h' (`get-info-help-node') - Try hard to visit the node `(info)Help'. The Info file - `info.texi' distributed with GNU Info contains this node. Of - course, the file must first be processed with `makeinfo', and then - placed into the location of your Info directory. - -Here are the commands for creating a numeric argument: - -`C-u' (`universal-argument') - Start (or multiply by 4) the current numeric argument. `C-u' is a - good way to give a small numeric argument to cursor movement or - scrolling commands; `C-u C-v' scrolls the screen 4 lines, while - `C-u C-u C-n' moves the cursor down 16 lines. - -`M-1' (`add-digit-to-numeric-arg') -`M-2' ... `M-9' - Add the digit value of the invoking key to the current numeric - argument. Once Info is reading a numeric argument, you may just - type the digits of the argument, without the Meta prefix. For - example, you might give `C-l' a numeric argument of 32 by typing: - - `C-u 3 2 C-l' - - or - - `M-3 2 C-l' - -`C-g' is used to abort the reading of a multi-character key sequence, -to cancel lengthy operations (such as multi-file searches) and to -cancel reading input in the echo area. - -`C-g' (`abort-key') - Cancel current operation. - -The `q' command of Info simply quits running Info. - -`q' (`quit') - Exit GNU Info. - -If the operating system tells GNU Info that the screen is 60 lines tall, -and it is actually only 40 lines tall, here is a way to tell Info that -the operating system is correct. - -`M-x set-screen-height' - Read a height value in the echo area and set the height of the - displayed screen to that value. - -Finally, Info provides a convenient way to display footnotes which might -be associated with the current node that you are viewing: - -`ESC C-f' (`show-footnotes') - Show the footnotes (if any) associated with the current node in - another window. You can have Info automatically display the - footnotes associated with a node when the node is selected by - setting the variable `automatic-footnotes'. *Note - `automatic-footnotes': Variables. - - -File: info-stnd.info, Node: Variables, Next: GNU Info Global Index, Prev: Miscellaneous Commands, Up: Top - -Manipulating Variables -********************** - -GNU Info contains several "variables" whose values are looked at by -various Info commands. You can change the values of these variables, -and thus change the behavior of Info to more closely match your -environment and Info file reading manner. - -`M-x set-variable' - Read the name of a variable, and the value for it, in the echo - area and then set the variable to that value. Completion is - available when reading the variable name; often, completion is - available when reading the value to give to the variable, but that - depends on the variable itself. If a variable does *not* supply - multiple choices to complete over, it expects a numeric value. - -`M-x describe-variable' - Read the name of a variable in the echo area and then display a - brief description of what the variable affects. - -Here is a list of the variables that you can set in Info. - -`automatic-footnotes' - When set to `On', footnotes appear and disappear automatically. - This variable is `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 - `*Footnotes*'. If a node is selected which contains no footnotes, - and a `*Footnotes*' window is on the screen, the `*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. - -`automatic-tiling' - When set to `On', creating or deleting a window resizes other - windows. This variable is `Off' by default. Normally, typing - `C-x 2' divides the current window into two equal parts. When - `automatic-tiling' is set to `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 `*Completions*' and `*Footnotes*' are - *not* resized through automatic tiling; they remain their original - size. - -`visible-bell' - When set to `On', GNU Info attempts to flash the screen instead of - ringing the bell. This variable is `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 `errors-ring-bell' variable to `Off'. - -`errors-ring-bell' - When set to `On', errors cause the bell to ring. The default - setting of this variable is `On'. - -`gc-compressed-files' - When set to `On', Info garbage collects files which had to be - uncompressed. The default value of this variable is `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. `gc-compressed-files' tells - Info it is okay to garbage collect the text of the nodes of a file - which was compressed on disk. - -`show-index-match' - When set to `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 `On'. - When Info displays the location where an index match was found, - (*note `next-index-match': Searching Commands.), the portion of the - string that you had typed is highlighted by displaying it in the - inverse case from its surrounding characters. - -`scroll-behavior' - Control 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 - `Continuous'. There are three possible values for this variable: - - `Continuous' - Try to get the first item in this node's menu, or failing - that, the `Next' node, or failing that, the `Next' of the - `Up'. This behavior is identical to using the `]' - (`global-next-node') and `[' (`global-prev-node') commands. - - `Next Only' - Only try to get the `Next' node. - - `Page Only' - Simply give up, changing nothing. If `scroll-behavior' is - `Page Only', no scrolling command can change the node that is - being viewed. - -`scroll-step' - The number of lines to scroll when the cursor moves out of the - window. Scrolling happens automatically if the cursor has moved - out of the visible portion of the node text when it is time to - display. Usually the scrolling is done so as to put the cursor on - the center line of the current window. However, if the variable - `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. - -`ISO-Latin' - When set to `On', Info accepts and displays ISO Latin characters. - By default, Info assumes an ASCII character set. `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. - - -File: info-stnd.info, Node: GNU Info Global Index, Prev: Variables, Up: Top -
