<p>The <code>widget</code> object can be accessed via the window object <code>window.widget</code> or simply <code>widget</code>. Thus, in the WRT environment, the term <code>widget</code> is a reserved keyword and should not be used as a user-defined global variable name representing other objects or data types.</p>
