1 11 Miscellaneous Commands
1 *************************
1
1 GNU Info contains several commands which self-document GNU Info:
1
1 'M-x describe-command'
1 Read the name of an Info command in the echo area and then display
1 a brief description of what that command does.
1
1 'M-x describe-key'
1 Read a key sequence in the echo area, and then display the name and
1 documentation of the Info command that the key sequence invokes.
1
1 'M-x describe-variable'
1 Read the name of a variable in the echo area and then display a
1 brief description of what the variable affects.
1
1 'M-x where-is'
1 Read the name of an Info command in the echo area, and then display
1 a key sequence which can be typed in order to invoke that command.
1
1 'H' ('get-help-window')
1 <F1> (on DOS/Windows only)
1 Create (or Move into) the window displaying '*Help*', and place a
1 node containing a quick reference card into it. This window
1 displays the most concise information about GNU Info available.
1
1 'h' ('get-info-help-node')
1 Try hard to visit the node '(info)Help'. The Info file 'info.texi'
1 distributed with GNU Emacs contains this node. Of course, the file
1 must first be processed with 'makeinfo', and then placed into the
1 location of your Info directory.
1
1 '=' ('display-file-info')
1 Show information about what's currently being viewed in the echo
1 area: the Info file name, and current line number and percentage
1 within the current node.
1
1 'M-x info-version'
1 Display the name and version of the currently running Info program.
1
1 Here are the commands for creating a numeric argument:
1
1 'C-u' ('universal-argument')
1 Start (or multiply by 4) the current numeric argument. 'C-u' is a
1 good way to give a small numeric argument to cursor movement or
1 scrolling commands; 'C-u C-v' scrolls the screen 4 lines, while
1 'C-u C-u C-n' moves the cursor down 16 lines. 'C-u' followed by
1 digit keys sets the numeric argument to the number thus typed: 'C-u
1 1 2 0' sets the argument to 120.
1
1 'M-1' ('add-digit-to-numeric-arg')
1 '1', vi-like operation
1 'M-2' ... 'M-9'
1 '2' ... '9', vi-like operation
1 'M-0'
1 '0', vi-like operation
1 Add the digit value of the invoking key to the current numeric
1 argument. Once Info is reading a numeric argument, you may just
1 type the digits of the argument, without the Meta prefix. For
1 example, you might give 'C-l' a numeric argument of 32 by typing:
1
1 C-u 3 2 C-l
1
1 or
1
1 M-3 2 C-l
1
1 'M--' ('add-digit-to-numeric-arg')
1 '-'
1 To make a negative argument, type '-'. Typing '-' alone makes a
1 negative argument with a value of -1. If you continue to type
1 digit or Meta-digit keys after '-', the result is a negative number
1 produced by those digits.
1
1 '-' doesn't work when you type in the echo area, because you need
1 to be able to insert the '-' character itself; use 'M--' instead,
1 if you need to specify negative arguments in the echo area.
1
1 <C-g> is used to abort the reading of a multi-character key sequence,
1 to cancel lengthy operations (such as multi-file searches) and to cancel
1 reading input in the echo area.
1
1 'C-g' ('abort-key')
1 Cancel current operation.
1
1 The 'q' command of Info simply quits running Info.
1
1 'q' ('quit')
1 'C-x C-c'
1 Exit GNU Info.
1
1 If the operating system tells GNU Info that the screen is 60 lines
1 tall, and it is actually only 40 lines tall, here is a way to tell Info
1 that the operating system is correct.
1
1 'M-x set-screen-height'
1 Read a height value in the echo area and set the height of the
1 displayed screen to that value.
1
1 On MS-DOS/MS-Windows, this command actually tries to change the
1 dimensions of the visible screen to the value you type in the echo area.
1
1 Finally, Info provides a convenient way to display footnotes which
1 might be associated with the current node that you are viewing:
1
1 'ESC C-f' ('show-footnotes')
1 Show the footnotes (if any) associated with the current node in
1 another window. You can have Info automatically display the
1 footnotes associated with a node when the node is selected by
11 setting the variable 'automatic-footnotes'. ⇒
'automatic-footnotes' Variables.
