The present approach includes presenting an e-book having content, in which the content includes selected content and non-selected content. The method includes receiving a first prompt to hide the selected content of the e-book and hiding the selected content, in response to the first prompt, while presenting the non-selected content of the e-book. The method further includes receiving a second prompt to reveal the hidden content of the e-book and temporarily revealing the hidden content, in response to the second prompt, while presenting the non-selected content of the e-book. |
