To set the increment or decrement value of a slider, set the <b>step</b> .<span class="Apple-converted-space">  </span>By default, the shift, ctrl, and alt keys will modify the stepping by 100x, 10x, or 0.1x repectively, though you can customize this by setting <b>shift_scale, ctrl_scale, </b>or<b> alt_scale.</b></p>
