After OnCue has finished processing and adding documents, they will appear in the Documents section of the Media Bar. Each document can be expanded to show pages. Why are some of my pages blue and some gray? Blue indicates a color page, gray is black and white. If you don't already see the Viewer pane, double clicking on a document page will launch it. Selecting Annotate Documents from the Workflow Ribbon will give the best layout to view docs as well.
Right clicking on any page will bring up a context sensitive menu offering additional options:
Some of these options will be grayed-out since they don't apply to documents, but others, such as Document Cleanup, can be used on groups of documents or individual pages.
