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.
