-      # The first argument +name+ is used as the link text.
-      #
-      # The next arguments are optional and may include the javascript function definition and a hash of html_options.
-      #
-      # The +function+ argument can be omitted in favor of an +update_page+
-      # block, which evaluates to a string when the template is rendered
-      # (instead of making an Ajax request first).
-      #
-      # The +html_options+ will accept a hash of html attributes for the link tag. Some examples are :class => "nav_button", :id => "articles_nav_button"
-      #
-      # Note: if you choose to specify the javascript function in a block, but would like to pass html_options, set the +function+ parameter to nil
+      # The helper receives a name, JavaScript code, and an optional hash of HTML options. The
+      # name is used as the link text and the JavaScript code goes into the +onclick+ attribute.
+      # If +html_options+ has an <tt>:onclick</tt>, that one is put before +function+. Once all
+      # the JavaScript is set, the helper appends "; return false;".
       #
+      # The +href+ attribute of the tag is set to "#" unles +html_options+ has one.
