Miscellaneous Commands
**********************

GNU Info contains several commands which self-document GNU Info:

`M-x describe-command'
     Read the name of an Info command in the echo area and then display
     a brief description of what that command does.

`M-x describe-key'
     Read a key sequence in the echo area, and then display the name and
     documentation of the Info command that the key sequence invokes.

`M-x describe-variable'
     Read the name of a variable in the echo area and then display a
     brief description of what the variable affects.

`M-x where-is'
     Read the name of an Info command in the echo area, and then display
     a key sequence which can be typed in order to invoke that command.

`C-h' (`get-help-window')
`?'
     Create (or Move into) the window displaying `*Help*', and place 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')
     Try 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.

Here are the commands for creating a numeric argument:

`C-u' (`universal-argument')
     Start (or multiply 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'
     Add 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 Meta prefix.  For
     example, you might give `C-l' a numeric argument of 32 by typing:

          C-u 3 2 C-l

     or

          M-3 2 C-l

`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.

`C-g' (`abort-key')
     Cancel current operation.

The `q' command of Info simply quits running Info.

`q' (`quit')
     Exit GNU Info.

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.

`M-x set-screen-height'
     Read a height value in the echo area and set 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')
     Show 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': Variables.
