Miscellaneous
commands
GNU
info
contains several commands which self-document GNU info
as the following discussions help to clarify.
-
M-x
(describe-command)
-
Reads the name of an info
command in the echo area and then displays a brief description of
what that command does.
-
M-x
(describe-key)
-
Reads a key sequence in the
echo area, and then displays the name and documentation of the info
command which a given key sequence invokes.
-
M-x
(describe-variable)
-
Reads the name of a variable
in the echo area and then displays a brief description of what the variable
affects.
-
M-x
(where-is)
-
Reads the name of an info
command in the echo area, and then displays a key sequence which
can be typed in order to invoke that command.
-
C-h
(get-help-window)
-
?
-
Creates (or moves into) the
window displaying *Help*,
and places 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)
-
Tries 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.
The following are the commands
for creating a numeric argument.
-
C-u
(universal-argument)
-
Starts (or multiplies 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
-
Adds 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 M
prefix. For example, you might give C-1
a numeric argument of 32
by using the keystroke sequence, C-u,
3,
2,
C-1 or
M-3,
2,
C-1.
-
C-g
(abort-key)
-
Cancels current operation. 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.
-
q
(quit)
If the operating system tells
info
that the screen is 60 lines tall, and it is actually only 40 lines
tall, the following is a way to tell info
that the operating system is correct.
M-x
set-screen-height
Reads a height value in
the echo area and sets 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)
-
Shows 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.
See automatic-footnotes
in Manipulating
variables.
