+Highlighting matching parens			*matchparen*
+
+The functionality mentioned here is a |standard-plugin|.
+This plugin is only available if 'compatible' is not set.
+
+You can avoid loading this plugin by setting the "loaded_matchparen" variable: >
+	:let loaded_matchparen = 1
+
+The plugin installs CursorMoved autocommands to redefine the match
+highlighting.
+
+To disable the plugin after it was loaded use this command: >
+
+	:NoMatchParen
+
+And to enable it again: >
+
+	:DoMatchParen
+
+The highlighting used is ParenMatch.  You can specify different colors with
+the ":highlight" command.  Example: >
+
+	:hi ParenMatch ctermbg=blue guibg=lightblue
+
+The characters to be matched come from the 'matchpairs' option.  You can
+change the value to highlight different matches.  Note that not everything is
+possible.  For example, you can't highlight single or double quotes, because
+the start and end are equal.
+
+The syntax highlighting attributes are used.  When the cursor currently is not
+in a string or comment syntax item, then matches inside string and comment
+syntax items are ignored.  Any syntax items with "string" or "comment"
+somewhere in their name are considered string or comment items.
