viper: Emacs State

 
 1.3.1 Emacs State
 -----------------
 
 You will be in this mode only by accident (hopefully).  This is the
 state Emacs is normally in (imagine!!).  Now leave it as soon as
 possible by typing ‘C-z’.  Then you will be in Vi state (sigh of relief)
 :-).
 
    Emacs state is actually a Viperism to denote all the major and minor
 modes (Emacs Preliminaries) other than Viper that Emacs can be
 in.  Emacs can have several modes, such as C mode for editing C
 programs, LaTeX mode for editing LaTeX documents, Dired for directory
 editing, etc.  These are major modes, each with a different set of
 key-bindings.  Viper states are orthogonal to these Emacs major modes.
 The presence of these language sensitive and other modes is a major win
 over Vi.  Improvements over Vi, for more.
 
    The bindings for these modes can be made available in the Viper
 Insert state as well as in Emacs state.  Unless you specify your user
 level as 1 (a novice), all major mode key sequences that start with
 ‘C-x’ and ‘C-c’ are also available in Vi state.  This is important
 because major modes designed for editing files, such as cc-mode or
 latex-mode, use key sequences that begin with ‘C-x’ and ‘C-c’.
 
    There is also a key that lets you temporarily escape to Vi command
 state from the Insert state: typing ‘C-z’ will let you execute a single
 Vi command while staying in Viper’s Insert state.
