There are two primary ways to launch your exhibits into OnCue LIVE.
You can launch a blank screen in OnCue LIVE by hitting Ctrl +F5. You can then type an ID in Live preceded by an "x", for example "x27.4" will bring up the fourth page of exhibit 27. The default is "x" but you can change that (see Presentation Settings and Preferences.)
Launching in extended desktop mode to the projector/monitor by selecting anything in OnCue and hitting the F5 button.
