 Re-runs the previous select to allow you to chain actions together on the
 same selector.
 
+=head1 AUTOLOAD METHODS
+
+L<HTML::Zoom> AUTOLOADS methods against L</select> so that you can reduce a
+certain amount of boilerplate typing.  This allows you to replace:
+
+  $z->select('div')->replace_content("Hello World");
+  
+With:
+
+  $z->replace_content(div => "Hello World");
+  
+Besides saving a few keys per invocations, you may feel this looks neater
+in your code and increases understanding.
