Trying to do some stutter editing (for effect) and I see how to get audio to snap to zero crossing, but can't find any way to tell split tool to split at the closest zero crossing. Getting clicks. :( 

In the snap to grid functions, there is an option to snap to zero crossings :

I have that set, still getting clicks. 
 
I'm just leaving the clips in place now and muting every other one, getting clicks every time.
 

Sorry. I'm so used to editing the clips after split that I never noticed it clicked if you do no farther editing.  I think if you use audiosnap to split you can place an autofade on the clips.

Select all clips is the track and try the clip fades.

Let me start by pointing out that splitting/muting at zero crossings is no guarantee you won't have clicks. The rate of change in amplitude of a waveform (and therefore your monitors' drivers) are at maximum at a zero crossing, and stopping the signal there still creates a discontinuity that will be heard as a click unless the amplitude is also low (which it should be if you're choosing split points musically). A short fade (maybe 3-5ms) will usually be needed to fully eliminate clicks where there's significant amplitude around the zero crossing.
 
That said, I've found that Snap to Zero Crossing seems not to be working in lanes except for slip-editing clip boundaries. All tools snap to zero in the parent track as expected, but selections, splits and comps are not snapping to zero crossings in lanes. This may have come up before. I haven't checked to see how far back it goes, but I know there have been complaints about failure to snap to zero in previous versions.

Yeah, as I said before, I'm slicing up a pad so you're probably correct about the source of my clicks. That's disappointing, because I really wanted it to sound like a gate slamming on and off. I may be able to achieve that effect with very short fades, I'll have to zoom way in and experiment. Thanks. :-)
