This Jigsaw feature, My Presentations, is simply the sharing of PowerPoint files with session attendees. When the presenter has shared a file, each attendee may independently open and view the file.
To view My Presentations, locate and select My Presentations in pane 4's menu. If you do not have My Presentations, the presenter has not shared any with you.
Select the file and…open. Use the forward and back arrows to change pages.
The “presentation” button opens the list of presentations that has been shared.
To open a different presentation, select the file then…open.
