There are two methods by which you can make configuration changes to individual slides:

First, you can click when the slide you want to modify is displayed in the NOC Viewer. Doing so stops the NOC Viewer from proceeding to the next slide in the deck and allows you to make the necessary changes without navigating away from the page. When finished, click , then click to start the NOC Viewer from the current slide.

Or, you can first access the NOC Viewer Library, select the slide deck which contains the slide you'd like to modify, then click the Edit icon to launch the Edit View deck dialog. From here, you can:

Edit an individual slide. Select any slide, then click the Edit icon. This launches the Edit view dialog where modifications to the slide can be made just as if you had selected Configure view before adding to slide deck as described previously.
Copy an individual slide. Select any slide, then click the Copy icon. This launches the Edit view dialog with a copy of the selected slide displayed. Configure the copy as needed to create a new slide, then click Save.
Delete an individual slide. Select any slide, then click the Delete icon. This removes the selected slide from the slide deck.
Change the order of slides. Select any slide, then use the up or down arrow icons to modify the order in which slides will be displayed in the NOC Viewer.
Change slide duration. Select one or more slides, then click Bulk change duration. Use the controls provided in the dialog that appears to modify the length of time the selected slide(s) will be be displayed, the click OK.
