Thanks, JohnM. I've checked the shortcuts, and at the moment the appropriate keyes work as they should: down arrow for next slide, up arrow for previous; right/left arrows for next/previous service item. When I select the X button to change that key stroke, a box pops up telling me that shortcut is already in use and I need to choose another key. That happens with pretty much every one I try to change. In any case, if I change the shortcuts as you suggested, that will change the 'normal' actions of the arrow keys when not using the remote. I'm not sure that's what I need! The problem seems to be related to a difference between the two Logitech remotes, and even then, only on OpenLP. They both behave the same on Powerpoint and in Easyworship.
