viper: Editing in Insert State

 
 4.2.4 Editing in Insert State
 -----------------------------
 
 Minibuffer can be edited similarly to Insert state, and you can switch
 between Insert/Replace/Vi states at will.  Some users prefer plain Emacs
 feel in the minibuffer.  To this end, set VIPER-VI-STYLE-IN-MINIBUFFER
 to ‘nil’.
 
 ‘C-v’
      Deprive the next char of its special meaning (quoting).
 ‘C-h’
      One char back.
 ‘C-w’
      One word back.
 ‘C-u’
      Back to the begin of the change on the current line.
