viper: Improved Search

 
 2.6 Improved Search
 ===================
 
 Viper provides buffer search, the ability to search the buffer for a
 region under the cursor.  You have to turn this on in your Viper
 customization file either by calling
 
      (viper-buffer-search-enable)
 
 or by setting ‘viper-buffer-search-char’ to, say, ‘f3’:
      (setq viper-buffer-search-char ?g)
 
 If the user calls ‘viper-buffer-search-enable’ explicitly (the first
 method), then ‘viper-buffer-search-char’ will be set to ‘g’.  Regardless
 of how this feature is enabled, the key ‘viper-buffer-search-char’ will
 take movement commands, like ‘w,/,e’, to find a region and then search
 for the contents of that region.  This command is very useful for
 searching for variable names, etc., in a program.  The search can be
 repeated by ‘n’ or reversed by ‘N’.
 
    Emacs provides incremental search.  As you type the string in, the
 cursor will move to the next match.  You can snarf words from the buffer
 as you go along.  Incremental Search is normally bound to ‘C-s’ and
 ‘C-r’.  Customization, to find out how to change the bindings of
 ‘C-r or C-s’.  For details, Incremental Search (emacs)Incremental
 Search.
 
    Viper also provides a query replace function that prompts through the
 minibuffer.  It is invoked by the ‘Q’ key in Vi state.
 
    On a window display, Viper supports mouse search, i.e., you can
 search for a word by clicking on it.  Viper Specials, for
 details.
 
    Finally, on a window display, Viper highlights search patterns as it
 finds them.  This is done through what is known as _faces_ in Emacs.
 The variable that controls how search patterns are highlighted is
 ‘viper-search-face’.  If you don’t want any highlighting at all, put
      (copy-face 'default 'viper-search-face)
 in your Viper customization file.  If you want to change how patterns
 are highlighted, you will have to change ‘viper-search-face’ to your
 liking.  The easiest way to do this is to use Emacs customization
 widget, which is accessible from the menubar.  Viper customization group
 is located under the _Emulations_ customization group, which in turn is
 under the _Editing_ group (or simply by typing ‘:customize’).  All Viper
 faces are grouped together under Viper’s _Highlighting_ group.
 
    Try it: it is really simple!
