This file documents GNU Info, a program for viewing the on-line formatted versions of Texinfo files, version 4.0. This documentation is different from the documentation for the Info reader that is part of GNU Emacs.
This manual is for Info version 4.0, updated 28 September 1999.
Info is a program which is used to view Info files on an ASCII
terminal. Info files are the result of processing Texinfo files
with the program makeinfo
or with one of the Emacs commands, such
as M-x texinfo-format-buffer
. Texinfo itself is a documentation
system that uses a single source file to produce both on-line
information and printed output. You can typeset and print the files
that you read in Info.
GNU Info accepts several options to control the initial node being viewed, and to specify which directories to search for Info files. Here is a template showing an invocation of GNU Info from the shell:
info [option]... [menu-item...]
The program accepts the following options:
--apropos=string
--directory directory-path
-d directory-path
--directory
multiple times; once for each directory which contains Info files. The
list of directories searched by Info is constructed from the value of
the environment variable INFOPATH
; --directory
causes the
named directory-path to be prepended to that list. The value of
INFOPATH
is a list of directories usually separated by a colon;
on MS-DOS/MS-Windows systems, the semicolon is used. If you do not
define INFOPATH
, Info uses a default path defined when Info was
built as the initial list of directories. If the value of
INFOPATH
ends with a colon (or semicolon on MS-DOS/MS-Windows),
the initial list of directories is constructed by appending the
build-time default to the value of INFOPATH
.
--dribble=dribble-file
--restore
option below.
--file filename
-f filename
dir
; if you use this option, Info will start with
(filename)Top
as the first file and node.
If filename is an absolute file name, or begins with ./
or
../
, Info looks for filename only in the directory of the
specified filename, and adds the directory of filename to
the value of INFOPATH
. In contrast, if filename is in the
form of a relative file name, but without the ./
or ../
prefix, Info will only look for it in the directories specified in
INFOPATH
. In other words, Info does not treat file names
which lack ./
and ../
prefix as relative to the current
directory.
In every directory Info tries, if filename is not found, Info
looks for it with a number of known extensions of Info files1. For every
known extension, Info looks for a compressed file, if a regular file
isn't found. Info supports files compressed with gzip
,
bzip2
, compress
and yabba
programs; it calls
gunzip
, bunzip2
, uncompress
and unyabba
,
accordingly, to decompress such files. Compressed Info files are
assumed to have .z
, .gz
, .bz2
, .Z
, or
.Y
extensions, possibly in addition to one of the known Info
files extensions2.
--help
-h
--index-search string
no
entries found
and exit with nonzero status. This can be used from
another program as a way to provide online help, or as a quick way of
starting to read an Info file at a certain node when you don't know the
exact name of that node.
--node nodename
-n nodename
--file
3. 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
-
for filename specifies
the standard output.
--restore=dribble-file
--dribble
option above). When the keystrokes in the files are all read, Info
reverts its input to the usual interactive operation.
--show-options
--usage
-O
M-x goto-invocation
command (see goto-invocation) from inside
Info.
--speech-friendly
-b
--subnodes
--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.
--version
--vi-keys
vi
and Less. The default key bindings are generally
modeled after Emacs.
menu-item
dir
), the second argument is a menu item in the first argument's
node, etc. 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
.
To avoid searching the dir
files and just show some arbitrary
file, use -f
and the filename, as in info -f ./foo.info
.
The index search and the search for the node which describes program
invocation and command-line options begins after processing all
the command-line menu items. Therefore, the Info file searched for the
index or the invocation node is the file where Info finds itself after
following all the menu items given on the command line. This is so
info emacs --show-options
does what you'd expect.
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. See Characters, if you are unfamiliar with the notation4.
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
5 command name (displayed in parentheses), and a short
description of what the command does. All of the cursor motion commands
can take a numeric argument (see universal-argument
. 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.

move-to-window-line
)
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.
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.
Scrolling commands are bound differently when --vi-keys
operation
(see -vi-keys) is in effect. These key bindings are designated
with "vi-like operation".
scroll-forward
)
The default scroll size is one screen-full, but it can be changed by
invoking the (scroll-forward-set-window
) command, z
under
--vi-keys
, with a numeric argument.
The <NEXT> key is known as the <PageDown> key on some
keyboards. When you use <NEXT> or <PageDown> to scroll, Info
never scrolls beyond the end of the current node.
scroll-forward-set-window

and scroll-backward
commands.
scroll-backward

scroll-forward

invoking the(scroll-backward-set-window
) command, w

--vi-keys
, with a numeric argument.

scroll-half-screen-down
, vi-like operation)
d
and u
commands.
scroll-half-screen-up
, vi-like operation)
u
and d
commands.
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
. See scroll-behavior
, for more information.
The <PREVIOUS> key is the <PageUp> key on many keyboards. Emacs refers to it by the name <PRIOR>. When you use <PRIOR> or <PageUp> to scroll, Info never scrolls beyond the beginning of the current node.
If your keyboard lacks the <DEL> key, look for a key called
<BS>, or BackSpace
, sometimes designated with an arrow which
points to the left, which should perform the same function.
redraw-display
)
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.
toggle-wrap
)
\
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. When long lines are truncated, the modeline displays the
$
character near its left edge.
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
. Note that the commands to select nodes are mapped differently
when --vi-keys
is in effect; these keybindings are designated
below as "vi-like operation".
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:
next-node
)
The <NEXT> key is known as the <PgDn> key on some
keyboards.
prev-node
)
The <PREVIOUS> key is known as the <PgUp> key on some
keyboards.
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 backwards through the history of visited nodes for this
window. This is handy when you followed a reference to another node,
possibly to read about a related issue, and would like then to resume
reading at the same place where you started the excursion.
Each node where you press l
is discarded from the history. Thus,
by the time you get to the first node you visited in a window, the
entire history of that window is discarded.
history-node
)
Two additional commands make it easy to select the most commonly
selected nodes; they are t
and d
.
top-node
)
Top
in the current Info file.
dir-node
)
(dir)
).
Here are some other commands which immediately result in the selection of a different node in the current window:
first-node
)
Top
, but it does not have to be. With a numeric argument
N, select the Nth node (the first node is node 1). An
argument of zero is the same as the argument of 1.
last-node
)
global-next-node
)
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
)
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>; See scroll-behavior
, for
more information.
goto-node
)
g(emacs)Buffers
finds the node Buffers
in the Info file emacs
.
goto-invocation
--show-options
command-line option (see -show-options), but
it also allows to specify the program name; this is important for those
manuals which describe several programs.
If you need to find the Invocation node of a program that is documented
in another Info file, you need to visit that file before invoking
I
. For example, if you are reading the Emacs manual and want to
see the command-line options of the makeinfo
program, type g
(texinfo) <RET> and then I makeinfo <RET>. If you don't
know what Info file documents the command, or if invoking I
doesn't display the right node, go to the (dir)
node (using the
d
command) and invoke I
from there.
menu-sequence
)
(dir)
(if the (dir)
node cannot be found, Info
uses Top
). If such an entry is found, Info goes to the node it
points to and looks up the second item in the menu of that node, etc.
In other words, you can specify a complete path which descends through
the menu hierarchy of a particular Info file starting at the
(dir)
node. This has the same effect as if you typed the menu
item sequence on Info's command line, see Info command-line arguments processing. For example,
G Texinfo,Overview,Reporting Bugs <RET>
displays the node Reporting Bugs
in the Texinfo manual. (You
don't actually need to type the menu items in their full length, or in
their exact letter-case. However, if you do type the menu items
exactly, Info will find it faster.)
If any of the menu items you type are not found, Info stops at the last
entry it did find and reports an error.

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.

search-next
)
search-previous
)
isearch-forward
)
isearch-backward
)
index-search
)
next-index-match
)
i
command.
The most basic searching command is s
or /
(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. Under
--vi-keys
(see -vi-keys), using the n
or N
commands is a faster way of searching for the same 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.
Both incremental and non-incremental search by default ignore the case
of letters when comparing the Info file text with the search string.
However, an uppercase letter in the search string makes the search
case-sensitive. You can force a case-sensitive non-incremental search,
even for a string that includes only lower-case letters, by using the
S
command (search-case-sensitively
). The n
and
N
commands operate case-sensitively if the last search command
was S
.
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.
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: See xref, for more information on creating your own texinfo cross
references.
The following table lists the Info commands which operate on menu items.
menu-digit
)
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. When --vi-keys
is in
effect, digits set the numeric argument, so these commands are remapped
to their M-
varieties. For example, to select the last menu
item, press <M-0>.
last-menu-item

This table lists the Info commands which operate on cross references.
xref-item

Finally, the next few commands operate on menu or note references alike:
move-to-next-xref
)
select-reference-this-line
) to select the menu or note reference.
move-to-prev-xref

On DOS/Windows only, the Shift-<TAB> key is an alias for
M-<TAB>. This key is sometimes called BackTab
.
select-reference-this-line
)
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.
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. In addition, if
the Info file containing the node has been split into subfiles, the name
of the subfile containing the node appears in the modeline as well:
--zz-Info: (emacs)Top, 291 lines --Top-- Subfile: emacs-1.Z-------------
Truncation of long lines (as opposed to wrapping them to the next
display line, see toggle-wrap) is indicated by a
$
at the left edge of the mode line:
--$--Info: (texinfo)Top, 480 lines --Top-- Subfile: texinfo-1-----------
When Info makes a node internally, such that there is no corresponding
info file on disk, the name of the node is surrounded by asterisks
(*
). The name itself tells you what the contents of the window
are; the sample mode line below shows an internally constructed node
showing possible completions:
-----Info: *Completions*, 7 lines --All---------------------------------
It can be convenient to view more than one node at a time. To allow
this, Info can display more than one window. Each window has its
own mode line (see The Mode Line) and history of nodes viewed in that
window (see history-node
).
next-window
)
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.

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:
echo-area-forward
)
echo-area-backward
)
echo-area-beg-of-line
)
echo-area-end-of-line
)
echo-area-forward-word
)
On DOS/Windows, C-<RIGHT> moves forward by words.
echo-area-backward-word
)
On DOS/Windows, C-<LEFT> moves backward by words.
echo-area-delete
)
echo-area-rubout
)
On some keyboards, this key is designated <BS>, for
BackSpace
. Those keyboards will usually bind <DEL> in the
echo area to echo-area-delete
.
echo-area-abort
)
echo-area-newline
)
echo-area-quoted-insert
)
?
character
when Info prompts with completion.
echo-area-insert
)
M-
commands, are also inserted verbatim; this is useful
for terminals which support Latin scripts.
echo-area-tab-insert
)
On DOS/Windows only, the Shift-<TAB> key is an alias for
M-<TAB>. This key is sometimes called BackTab
.
echo-area-transpose-chars
)
The next group of commands deal with killing, and yanking text6. For an in depth discussion of killing and yanking, see Killing
echo-area-kill-word
)
echo-area-backward-kill-word
)
On some keyboards, the Backspace
key is used instead of
DEL
, so M-<Backspace>
has the same effect as
M-<DEL>
.
echo-area-kill-line
)
echo-area-backward-kill-line
)
echo-area-yank
)
echo-area-yank-pop
)
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:
echo-area-complete
)
echo-area-possible-completions
)
bar foliate food forget
and you have typed an f
, followed by ?
, Info will pop up a
window showing a node called *Completions*
which lists the
possible completions like this:
3 completions: 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
.
echo-area-scroll-completions-window
)
In general, we recommend that you use TeX to format the document and
print sections of it, by running tex
on the Texinfo source file.
However, you may wish to print out the contents of a node as a quick
reference document for later use, or if you don't have TeX installed.
Info provides you with a command for doing this.
INFO_PRINT_COMMAND
. If the variable does not
exist, the node is simply piped to lpr
(on DOS/Windows, the
default is to print the node to the local printer device, PRN
).
The value of INFO_PRINT_COMMAND
may begin with the >
character, as in >/dev/printer
, in which case Info treats the
rest as the name of a file or a device. Instead of piping to a command,
Info opens the file, writes the node contents, and closes the file,
under the assumption that text written to that file will be printed by
the underlying OS.
GNU Info contains several commands which self-document GNU Info:
get-help-window
)
*Help*
, and place
a node containing a quick reference card into it. This window displays
the most concise information about GNU Info available.
get-info-help-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:
universal-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. C-u
followed
by digit keys sets the numeric argument to the number thus typed:
C-u 1 2 0 sets the argument to 120.
add-digit-to-numeric-arg
)
C-l
a numeric argument of 32 by typing:
C-u 3 2 C-l
or
M-3 2 C-l
add-digit-to-numeric-arg
- doesn't work when you type in the echo area, because you need to
be able to insert the -
character itself; use M-- instead,
if you need to specify negative arguments in the echo area.
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.
abort-key
)
The q
command of Info simply quits running Info. Under
--vi-keys
(see -vi-keys), you can also exit with :q
or ZZ
.
quit
)
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.
On MS-DOS/MS-Windows, this command actually tries to change the dimensions of the visible screen to the value you type in the echo area.
Finally, Info provides a convenient way to display footnotes which might be associated with the current node that you are viewing:
show-footnotes
)
automatic-footnotes
. See automatic-footnotes
.
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.
Here is a list of the variables that you can set in Info.
automatic-footnotes
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
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
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
On
, errors cause the bell to ring. The default
setting of this variable is On
.
gc-compressed-files
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
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,
(see 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.
scroll-behavior
Continuous
. There
are three possible values for this variable:
Continuous
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
Next
node.
Page Only
scroll-behavior
is
Page Only
, no scrolling command can change the node that is being
viewed.
scroll-step
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
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.

.info
, -info
, /index
, and .inf
.
The MS-DOS version allows for the Info
extension, such as .inf
, and the short compressed file
extensions, such as .z
and .gz
, to be merged into a single
extension, since DOS doesn't allow more than a single dot in the
basename of a file. Thus, on MS-DOS, if Info looks for bison
,
file names like bison.igz
and bison.inz
will be found and
decompressed by gunzip
.
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 and whitespace from the shell as in: info --node
"(emacs)Buffers"
.
Here's a short summary. C-x means press the CTRL key and the key x. M-x means press the META key and the key x. On many terminals th META key is known as the ALT key. SPC is the space bar. The other keys are usually called by the names imprinted on them.
M-x
is also a command; it
invokes execute-extended-command
. See M-x, for more detailed
information.
Some people are used to calling these operations cut and paste, respectively.
