Moving doodads up and down

I'm having a little problem, a while ago I had to reinstall things on my comp, and the WE prefs got resetted, so I also lost my prev control settings. I want to move doodads up and down (make them float etc), but the ctrl page-up thingy doesnt work (I work on a mac).
So can anybody tell me what the name of the commands is to move doodads up and down in the Configure Controls menu, because I've serieusly searched and tried for about 40 minutes but I still haven't found it yet. (hope u peeps understand it, my english is bad)

I'm not sure about mac, my oppioning is that it pretty sucks, so i'm not 100% sure if this is right: press the num lock key, and then use ctrl+pg-up/down.

Nope, doesn't work, I don't need to know what key it is, but where I can find it in the Confiugre Control menu. thx for the help tho.

Try the funny looking button that looks like a fusion of #%, try clicking that and Pg up/Pg down.

If you don't know what I'm talking about on the funny button, it's the button that's only available to mac keyboards...

Tried that one, I tried like every combination I could think of, but it Didn't work o_O , I know it has too work, it worked before, but damn...

*edit*
Finally I found it in the Configure Controls menu: Selection Decrease Z. Selection Increase Z. they where both set up to work woth that funny key and the page-up/page-down keys, but that just didnt work, I changed it to diff keys so now it works again. thx for helping me.

Ok, good luck terraining than :>
