Component Views and Templates
From Joomla! Documentation
When following the Joomla 1.5 component MVC tutorial, I got stuck when trying to add more views and layouts - how could I preview them? A colleague tipped me off:
index.php?option=com_mycom&view=mycom&layout=display index.php?option=com_mycom&view=mycom&layout=alternate index.php?option=com_mycom&view=mycom&layout=edit
Hope this helps!
