Page Effects Animation Panel
The Animation Panel allows you to customize the animation
effect to be inserted on the page.

Page Effects Animation Panel
Maximum Number of Objects slider - This specifies
the maximum number of object that will appear on the screen. The top number
is 50 total objects, although some effect will limit this number to
something smaller.
Number of Objects at Startup - This will be the number of objects
that will appear on the screen initially for effects that introduce objects
a little at a time, such as falling snow.
Object Delay - This is the amount of time in milli-seconds between
objects entering the screen area. This control is not used in bounded area
effects.
Tip: Set the Number of Objects at Startup and Object entry delay so that
a relatively small number of objects appear at start up time.
Delay Between Steps - Time in milli-seconds between object moves. A
smaller number makes it appear the object is moving faster.
Animation Step Size - The amount, in pixels, that the object moves in
every step.
Variation of Moving Objects - The randomness of the object's
movement.
