viper: Search and Replace

 
 4.2.7 Search and Replace
 ------------------------
 
 Groundwork, for Ex address syntax.  Options, to see how
 to get literal (non-regular-expression) search and how to stop search
 from wrapping around.
 
 ‘C-c /’
      Toggle case-sensitive search.  With prefix argument, toggle
      vanilla/regular expression search.
 ‘<count> /<string>’
      To the <count>th occurrence of <string>.
 
      Viper does not parse search patterns and does not expand special
      symbols found there (e.g., ‘~’ is not expanded to the result of the
      previous substitution).
 
      After typing ‘/’ or ‘?’ all the usual Emacs minibuffer commands,
      such as ‘M-p’ and ‘M-n’ are available.  In addition, typing ‘C-s’
      will insert the last search string used by the Emacs incremental
      search command (which is bound to ‘C-s’ everywhere except in this
      case).
 
 ‘<count> ?<string>’
      To the <count>th previous occurrence of <string>.
 ‘<count> g<move>’
      Search for the text described by move.  (off by default)
 ‘n’
      Repeat latest ‘/’ ‘?’ (next).
 ‘N’
      Idem in opposite direction.
 ‘%’
      Find the next bracket and go to its match
 ‘:[x,y]g/<string>/<cmd>’
      Search globally [from line x to y] for <string> and execute the Ex
      <cmd> on each occurrence.
 ‘:[x,y]v/<string>/<cmd>’
      Execute <cmd> on the lines that don’t match.
 ‘#g<move>’
      Execute the last keyboard macro for each line in the region.  
      Macros and Registers, for more info.
 ‘Q’
      Query Replace.
 ‘:ta <name>’
      Search in the tags file where <name> is defined (file, line), and
      go to it.
 ‘:[x,y]s/<pat>/<repl>/<f>’
      Substitute (on lines x through y) the pattern <pat> (default the
      last pattern) with <repl>.  Useful flags <f> are ‘g’ for ‘global’
      (i.e., change every non-overlapping occurrence of <pat>) and ‘c’
      for ‘confirm’ (type ‘y’ to confirm a particular substitution, else
      ‘n’).  Instead of ‘/’ any punctuation character other than <space>
      <tab> and <lf> can be used as delimiter.
 
      Note: _The newline character (inserted as ‘C-qC-j’) can be used in
      <repl>_.
 ‘&’
      Repeat latest Ex substitute command, e.g., ‘:s/wrong/right’.
 ‘:global /<pattern>/<ex-command>’
 ‘:g /<pattern>/<ex-command>’
      Execute <ex-command> on all lines that match <pattern>.
 ‘:vglobal /<pattern>/<ex-command>’
 ‘:v /<pattern>/<ex-command>’
      Execute <ex-command> on all lines that do not match <pattern>.
