Suppose you want to have a slider control that does coarse adjustment of 
an input variable in a Manipulate (range 0 to 150, let's say), and then 
a much finer adjustment button or slider you can use to nudge that value 
up or down by a much smaller amount (steps of 0.001, let's say) near any 
critical transition points.

If the input variable to be controlled is x, I suppose one could have a 
coarse slider to set the value of x0 in the range 0 <= x0 <=150  and a 
fine slider to set x1 in the range  -0.001 <= x1 <= +0.001; and then have
x = x0+x1 as the first statement in the active part of the Manipulate.

Other better ways to do this?
