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?
