I might as well throw my own solution into the ring. Use a linear
expression to interpolate from the wiggled value to the keyframed value.
Point it to a slider expression. Something like this:

x =3D effect("Slider Control")("Slider");
w =3D wiggle(1, 5);
linear(x, 0, 1, value, w);

You can then use the slider to control the contribution of the wiggle.  In
the above example a slider value of 0 returns in the keyframed value and a
slider value of 1 returns the wiggled value.  Use your own wiggle() values
of course :)

Unless something has changed recently, animating the frequency or amplitude
with a slider will cause erratic behavior.
