Touch the screen with the stylus. You will see green concentric circles with 
the stylus as the center. The tip of the stylus represents a point-shaped
magnet, the circles show the diminishing strength of the magnetic field.
The outermost circle is the effect circle. The parts of the objects that 
are within the effect circle will move towards or away from the center,
depending on the Mode selection. Lift the stylus to stop the motion. 

Use the buttons on the left side to select another advanced tool.

<b>Mode
Select this option then touch + or - to change the choice from Attract 
to Repel.  
Select Attract when you want the points of the object within the effectt 
circle to move towards the stylus. Choose Repel to move the points away 
from the stylus.

<b>Strength
This option changes the size of the effect circle. Change the percentage 
by using the keypad or the +/- keys.  Choose a very small % to affect 
very small parts of the object. Only the points of the object within 
the effect circle will move.

<b>Speed
This option determines how fast the object is affected. The higher the %, 
the faster the points of the object will move.

<b>Smooth
This setting determines the number of points that are affected by the
magnet. Using the Smooth function on a square shows the difference 
between Smooth On and Off when the Strength is set to 100%:
When Smooth is Off, touching the center of the square will attract or
repel only the points of the square, because there are no points in 
between them. The result of using the magnet is still a four-point 
object.
Turning Smooth On adds a large number of points to the sides of the 
square.
The magnet will move these points, so you can change the the four-
point object to a completely different geometry. For example, if you
select repel and touch the center of the square, its sides will start
bulging out, ultimately turning the square into a circle.
