Is there a way to set-up Proclaim so that a mouse can be used to advance the slides. The church I am at does not have Wi-fi or any internet access so the Iphone app doesn't work. What I would like is to have the mouse up at the podium with me and advance through the sermon slides as needed. Is this possible or does someone need to be sitting at the computer to advance the slides? Thank you in advance for any help you can provide.
