	      | Aerial view | Virtual visit |  When Aerial view is selected, the 3D view displays your home 
          in 3 dimensions seen from a top point of view. In this mode, moving 
          the mouse to the left or to the right with its left button pressed makes 
          the home turn around a vertical axis located at home center ; moving 
          the mouse forward or backward with its left button pressed makes the 
          home turn around an horizontal axis ; rolling the mouse wheel zooms 
          in or out in the 3D view. When Virtual visit  is selected, the 3D view displays your home 
          in 3 dimensions seen from the point of view of a virtual visitor. In 
          this mode, moving the mouse to the left or to the right with its left 
          button pressed makes the visitor body turn to the left or to the right ; 
          moving the mouse forward or backward with its left button pressed makes 
          the visitor head turn up or down ; rolling the mouse wheel makes 
          the visitor move backward or forward.
 In both modes, the left arrow and right arrow keys have 
          the same effect as mouse lateral moves ; page up and page 
          down keys have the same effect as mouse moves forward and backward ; 
          up arrow and down arrow keys have the same effect as mouse 
          wheel. In Virtual visit mode, you can also use the home 
          and end keys to move up or down the visitor's point of view.

                let you display or hide navigation arrows in the top left corner 
                of the 3D view. The left, right, up and down navigation arrows 
                have the same effect as the matching keys of the keyboard, whereas 
                the two small up and down arrows at center have the same effect 
                as the page up and page down keys. |  When Virtual visit  is selected, a virtual visitor seen from 
          top is drawn simultaneously in the home plan. Its location and its angle 
          is updated simultaneously in the plan and 3D view with each move of 
          the visitor. This virtual visitor is surrounded by four indicators.
