NOTES: If a feature is not available in a presentation, the shortcut for it will not work in the player. The fast forward, jump forward, and jump backward shortcuts are not available as buttons in the player. When you use the jump forward and jump backward shortcuts, you will skip within the presentation a pre-determined amount-for example, Ctrl+] skips you 30 seconds forward in a presentation. If a chapter point appears before the pre-determined time, using the shortcut will take you to the chapter point instead. So if you use Ctrl+] and there is a chapter point before the 30 second interval, the shortcut will stop there. If you use Ctrl+] again, the shortcut will take you 30 seconds forward from the chapter point.
