Isn't the problem just a documentation bug? setAltIncrementValue does work,
but it is about what happens when you option-click in the slider area, not
what happens when you drag the knob. Normally when you click in the slider
area, the slider jumps to where you clicked; with setAltIncrementValue, it
jumps the amount you set as the value (when you hold down the Option key and
click in the slider area). m.
