If you answer "N", you continue where you left off. :RA While text is on the screen pressing "R" restarts the section (erasing any previous answers that you may have entered), pressing "M" takes you to the last menu displayed and pressing "Q" enables you to quit. :RA The left-arrow key lets you page backwards through the text one screen at a time until the first screen of the section is reached. When a question appears on the screen, your previous answer, if any, is shown. You can replace that answer by entering another one, or you can leave your answer undisturbed by pressing the left-arrow again. :RA Pressing the letter "O" leaves the current question temporarily unanswered and displays the next question. At the end of the section you have a chance to review all the unanswered questions. :ET :ET
