%
% The final reference card has six columns, three on each side.
% This file can be used to produce it in any of three ways:
% 1 column per page
%    produces six separate pages, each of which needs to be reduced to 80%.
%    This gives the best resolution.
% 2 columns per page
%    produces three already-reduced pages.
%    You will still need to cut and paste.
% 3 columns per page
%    produces two pages which must be printed sideways to make a
%    ready-to-use 8.5 x 11 inch reference card.
%    For this you need a dvi device driver that can print sideways.
% Which mode to use is controlled by setting \columnsperpage above.

\section{Loading Viper}

Just type \kbd{M-x viper-mode} followed by \kbd{RET}

OR put

(setq viper-mode t)
(require 'viper)

in .emacs

\section{Viper States}

Viper has four states: {\it emacs state}, {\it vi state}, {\it insert state}, 
{\it replace state}.
Mode line tells you which state you are in.
In emacs state you can do all the normal GNU Emacs editing.
This card explains only vi state and insert state (replace state is similar
to insert state).
{\bf GNU Emacs Reference Card} explains emacs state.
You can switch states as follows.

\key{from emacs state to vi state}{C-z}
\key{from vi state to emacs state}{C-z}
\key{from vi state to emacs state for 1 command}{$\backslash$}
\metax{from vi state to insert state}{i, I, a, A, o, O}
\metax{from vi state to replace state}{c, C, R}
\key{from insert or replace state to vi state}{ESC}
\key{from insert state to vi state for 1 command}{C-z}


\section{Insert Mode}
You can do editing in insert state.

\metax{go back to vi state}{ESC}
\metax{delete previous character}{C-h, DEL}
\key{delete previous word}{C-w}
\key{delete line word}{C-u}
\key{indent shiftwidth forward}{C-t}
\key{indent shiftwidth backward}{C-d}
\key{delete line word}{C-u}
\key{quote following character}{C-v}
\key{emulate Meta key in emacs state}{C-$\backslash$}
\key{escape to Vi state for one command}{C-z}

\vskip 2mm

{\bf The rest of this card explains commands in {\bf vi state}.}

\section{Getting Information on Viper}

Execute info command by typing \kbd{M-x info} and select menu item
\kbd{viper}.  Also:

\key{describe function attached to the key {\it x}}{$\backslash$ C-h k {\it x}}

\section{Leaving Emacs}

\metax{suspend Emacs}{:st {\rm or} :su}
\metax{exit Emacs permanently}{C-xC-c}
\metax{exit current file}{:wq {\rm or} :q}

\shortcopyrightnotice

\section{Error Recovery}

\metax{abort command}{C-c (user level = 1)}
\metax{abort command}{C-g (user level > 1)}
\key{redraw messed up screen}{C-l}
\metax{{\bf recover} after system crash}{:rec file}
\metax{restore a buffer }{:e!\ {\rm or} M-x revert-buffer}


\section{Counts}

Most commands in vi state accept a {\it count} which can be supplied as a
prefix to the commands.  In most cases, if a count is given, the
command is executed that many times.  E.g., \kbd{5 d d} deletes 5
lines.

\section{Registers}

There are 26 registers (\kbd{a} to \kbd{z}) that can store texts
and marks.
You can append a text at the end of a register (say \kbd{x}) by
specifying the register name in capital letter (say \kbd{X}).
There are also 9 read only registers (\kbd{1} to \kbd{9}) that store
up to 9 previous changes.
We will use {\it x\/} to denote a register.
\section{Entering Insert Mode}

\key{{\bf insert} at point}{i}
\key{{\bf append} after cursor}{a}
\key{{\bf insert} before first non-white}{I}
\key{{\bf append} at end of line}{A}
\key{{\bf open} line below}{o}
\key{{\bf open} line above}{O}

\section{Buffers and Windows}

\key{move cursor to {\bf next} window}{C-x o}
\key{delete current window}{C-x 0}
\key{delete other windows}{C-x 1}
\key{split current window into two windows}{C-x 2}
\key{{\bf switch} to a buffer in the current window}{C-x {\sl buffer}}
\metax{{\bf switch} to a buffer in another window}{:n, :b, {\rm or} C-x 4 {\sl buf}}
