I am employing an NSSliderCell in my table view, and I want to slow down the rate of change or increase the resolution of change using a modifier key like commands as I drag. This is employed in a few audio programs to assist a mixer in fine tuning either volume or pan when mixing. Where do I start? I have bound my NSSliderCell to a NSNumber in my NSObjectController. Can anyone think of a way that I could modify the delta of change? Would I have to do this using a NSSliderCell subclass? Any thoughts?

Just an idea. (not tested at all) A possibility may be to override setDoubleValue: or whatever is used to set the cell value, and check if the current event ([NSApp currentEvent]) is a drag with ctrl down, and if this is the case compute the delta between the current value and the new value and reduce it proportionally before calling the super implementation.
