Thanks for the tip: "moi.grid.snapSize"!

I believe all I need for what I'd like Nudge to do is
view.upDownAngle
view.leftRightAngle
view.tiltAngle
What units are these in? Degrees?

I assume that upDownAngle==0 means looking in a horizontal direction. Are positive values up or down?

Are positive values of leftRightAngle left or right?

And what is tiltAngle?

Thanks again,
Christopher
