+query. Settings of this kind have values beginning with an exclamation mark, and take the form `!`_type_`!`_value_.
+
+The currently supported types are:
+
+* `param` -- uses the value of the specified query parameter for the URL. For example
+`<div class="mkws-results" autosearch="!param!term">` will auto-search for the word "sushi" if the page containing that widget is
+invoked from the URL `http://example.com/magic/example.html?term=sushi`
+
+* `path` -- uses the value of the _n_th component of the URL path, as specified by the value. For example
+`!path!3` will auto-search for the word "dinosaur" if the page containing that widget is
+invoked from the URL `http://example.com/magic/lookup/dinosaur`
