Endnote iPad app

Hi. The endnote iPad starting guide states " PDFs can be opened in other iPad applications that support PDF files." How is this possible? In other words, can I make another iPad app, the default PDF reader/annotation app while using endnote on my iPad? Can’t seem to figure out how. Thanks in advance. 

You would first need to locate a reference that has a pdf attached. Once you have clicked on the reference go down and click on the pdf file. Once the pdf is displayed the upper right action icon has several options including a “Open In” choice which should then allow you to pick the Application you want to use instead of the pdf viewer in EndNote.
