496     18. Modifiers

            •   Variable Amount  variable amounts let you choose some other
               value from any layer on the slide.  In short, any of the values that
               you can modify can be set as a variable.  You could use this type of
               variable to base any setting off another setting.  Use this to make
               Layer 2 move behind Layer 1, by modifying Layer 2’s pan values
               by the pan values for Layer 1.

               For a more detailed example, let’s say you use brightness – this
               means that as the brightness on your target layer changes, the
               action will take place. If you set the action to Add, and you set the
               variable to Brightness, you will get this example:

                   o   You have created a modifier for the Pan X value.  For
                       your action, you set it to Add. You choose Variable
                       Amount, and base it on the Brightness of another layer
                       on the slide. If you use an adjustment effect  that
                       changes the brightness of Layer 2, the Pan X value or
                       horizontal position of this modified layer will change.  If
                       the brightness increases, it will move right, or positive X.
                       If the brightness decreases, it will move left or negative
                       X.

               You can also set a Multiple. This can be used to make the change
               more obvious, so instead of being a 1:1 change in value, it would
               be a 1:2 or more.  Sometimes, the value you are using as your
               variable just won’t be dramatic enough.  The multiplier lets you
               amplify the effect to achieve the result you’re after.  For example,
               if we wanted Layer 2 to zoom twice as much as Layer 1, we’d
               base the zoom off Layer 1’s zoom, with a multiplier of 2.

            •   Amount from Function  the amount is the value from a
               mathematical function, represented by a waveform.  The
               waveform can be configured to appear the way you want it to
               appear.  The shape and value of the waveform determines how
               your action will behave.  When you look at the Waveform
               Preview for any particular wave, the way it cycles up and down
               directly relates to how the value will cycle up and down.  There are
