Sometimes, either due to lack of time or a particular subject matter, it is not practical to be required to type or click the answer when studying.  For this, there is the Flip Study screen.

There are seven buttons.  The bottom-most button obviously takes you back to the previous screen.  The center Left and Right buttons take you forward and backward through the cards.  The four other buttons determine how the cards are shown.  By default, one side is shown at random, and then pressing the Right button shows the other side as well.  If you click the left or right arrows, you can have that side always show.  The bottom-left button shows both sides simultaneous, for even more rapid study sessions.  This is represented by both arrows being selected.  The bottom-right sets the sides to be shown at random, and is represented by neither arrow selected.
