When you find a word that you'd like to learn more about tap and hold until the word turns blue. Let go and select define to view a dictionary definition and scroll down to see more options.
Once the definition window is open, you can type in a new word into the search box and tap the magnifying glass to learn more. Tap the ribbon icon to bookmark a page to remember it for later. Tap, hold and drag across a section of text to highlight it.
When you let go select highlight and choose from one of three colors. If you'd like to add a note type in the box and tap, save when you're finished, you can easily delete a note or highlight using the red trashcan icon to view your bookmarks, notes, and highlights for a title.
Tap this icon in the controls at the top of your screen.
