Hi Jesse - that Nudge script was just never set up to handle moving in the z direction.

I've tweaked the attached version to support it. If you use this new version, you can set PageUp and PageDown for z nudging, like:

PageDown	Nudge zdown
PageUp	Nudge zup

You should also be able to set up Ctrl+PageUp/down and Alt+PageUp/down for larger or smaller steps same as mentioned here: http://moi3d.com/forum/index.php?webtag=MOI&msg=952.3

Please let me know if you have any problems setting it up!
