Press ‘Menu’ on the bottom left hand corner of your screen. This will pull up several options for you, one of which will be to shuffle one or all chapters. Alternately, pressing ‘1’ on your keypad will shuffle one chapter and ‘3’ on your keypad will shuffle all chapters.

Take a look in the top right hand corner of your screen. An ‘SC’ means you have shuffled one chapter. ‘SA’ means you have shuffled all chapters.

Press ‘Menu’ on the bottom left hand corner of your screen. Among the options that are pulled up, there will be one to ‘Remove Card’. Pressing ‘7’ will also accomplish this. If you want to make sure the card has been removed, try going back to it. Presto, Change-o, Gone!

Close your eyes and wish it back.
Or...
Press ‘Menu’ on the bottom left hand corner of your screen. One of your options will say ‘Restore All’. Pressing ‘9’ will also accomplish this. Aaaaand they’re back. (If you can see them, they’re back)

This ‘Menu’ button is awesome, it has all the answers now doesn’t it? Press the magical ‘Menu’ button and select ‘Select Chapter’. This will give you the options to select or un-select chapters you wish to study. Pressing ‘2’ will take you to the previous chapter and pressing ‘8’ will take you to the next chapter.
