Caret browsing is a setting by which you can use your keyboard
to navigate a webpage rather than using your mouse. When
you turn this feature on, you can use the Home, End, and Page
Up, Down, Right, and Left keys to move from link to link or
to select text. Caret browsing can help the mouse challenged
enjoy their Web browsing experience more.
