.SH DESCRIPTION
|
|
.LP
|
|
The GNU project has a hypertext system called
|
|
.I Info
|
|
which allows the same source file to be either printed as a
|
|
paper manual, or viewed using
|
|
.B info.
|
|
It is possible to use the
|
|
.B info
|
|
program from inside Emacs, or to use the stand-alone version described here.
|
|
This manual page gives a brief summary of its capabilities.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-\-directory directory-path
|
|
Add
|
|
.B directory-path
|
|
to the list of directory paths searched when
|
|
.B info
|
|
needs to find a file. You may issue
|
|
.B \-\-directory
|
|
multiple times.
|
|
Alternatively, you may specify a value for the environment variable
|
|
.B INFOPATH;
|
|
if
|
|
.B \-\-directory
|
|
is not given, the value of
|
|
.B INFOPATH
|
|
is used. The value of
|
|
.B INFOPATH
|
|
is a colon separated list of directory names. If you do not supply either
|
|
.B INFOPATH
|
|
or
|
|
.B \-\-directory-path,
|
|
.B info
|
|
uses a default path.
|
|
.TP
|
|
.B \-f filename
|
|
Specify a particular
|
|
.B info
|
|
file to visit. By default,
|
|
.B info
|
|
visits
|
|
the file
|
|
.B dir;
|
|
if you use this option,
|
|
.B info
|
|
will start with
|
|
.B (FILENAME)Top
|
|
as the first file and node.
|
|
.TP
|
|
.B \-n nodename
|
|
Specify a particular node to visit in the initial file that
|
|
.B info
|
|
loads. This is especially useful in conjunction with
|
|
.B \-\-file.
|
|
You may specify
|
|
.B \-\-node
|
|
multiple times.
|
|
.TP
|
|
.B -o file
|
|
Direct output to
|
|
.B file
|
|
instead of starting an interactive
|
|
.B info
|
|
session.
|
|
.TP
|
|
.B \-h
|
|
Produce a relatively brief description of the available
|
|
.B info
|
|
options.
|
|
.TP
|
|
.B \-\-version
|
|
Print the version information of
|
|
.B info
|
|
and exit.
|
|
.TP
|
|
.B menu-item
|
|
.B 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,
|
|
|
|
.B info emacs buffers
|
|
|
|
first selects the menu item
|
|
.B emacs
|
|
in the node
|
|
.B (dir)Top,
|
|
and then selects the menu item
|
|
.B buffers
|
|
in the node
|
|
.B (emacs)Top.
|
|
.SH COMMANDS
|
|
When in
|
|
.B info
|
|
the following commands are available:
|
|
.TP
|
|
.B h
|
|
Invoke the Info tutorial.
|
|
.TP
|
|

|
|
Get a short summary of
|
|
.B info
|
|
commands.
|
|
.TP
|
|
.B h
|
|
Select the
|
|
.B info
|
|
node from the main directory; this is much more complete than just
|
|
using
|
|
.B ?.
|
|
.TP
|
|
.B Ctrl-g
|
|
Abort whatever you are doing.
|
|
.TP
|
|
.B Ctrl-l
|
|
Redraw the screen.
|
|
.PP
|
|
Selecting other nodes:
|
|
.TP
|
|
.B n
|
|
Move to the "next" node of this node.
|
|
.TP
|
|
.B p
|
|
Move to the "previous" node of this node.
|
|
.TP
|
|
.B u
|
|
Move to this node's "up" node.
|
|
.TP
|
|
.B m
|
|
Pick a menu item specified by name. Picking a menu item causes another
|
|
node to be selected. You do not need to type a complete nodename; if
|
|
you type a few letters and then a space or tab
|
|
.B info
|
|
will try to fill in the rest of the nodename. If you ask for further
|
|
completion without typing any more characters you'll be given a list
|
|
of possibilities; you can also get the list with
|
|
.B ?.
|
|
If you type a few characters and then hit return
|
|
.B info
|
|
will try to do a completion, and if it is ambigous use the first possibility.
|
|
.TP
|
|
.B f
|
|
Follow a cross reference. You are asked for the name of the reference,
|
|
using command completion as for
|
|
.B m.
|
|
.TP
|
|
.B l
|
|
Move to the last node you were at.
|
|
.PP
|
|
Moving within a node:
|
|
.TP
|
|
.B Space
|
|
Scroll forward a page.
|
|
.TP
|
|
.B DEL
|
|
Scroll backward a page.
|
|
.TP
|
|
.B b
|
