+ <P>When you press a button and drag to the right the value increases.
+ When you drag to the left it decreases. The largest button adjusts by
+ 100 * step(), the next by 10 * step() and that
+ smallest button by step(). Clicking on the buttons
+ increments by 10 times the amount dragging by a pixel does. Shift +
+ click decrements by 10 times the amount.
