How do you control Objectplace?

I can activate it, but not control (as in switching and placing items, like an emerald). What are the controls? This does not include movement.

I personally like using SRB2 doom builder's 3d mode to see the placement of my items. That way you don't have to get the thing lump and import it back into the wad so you can put it in the map.

Thanks a ton, JRose. Link bookmarked. As for Torgo, i'll keep it in mind.

EDIT: Ooookayy... I keep pressing THROW and the objects won't place themselves. (I'm on the JTE mod, on the taskbar it says v1.69)

EDIT 2: NVM, I just kept hitting the normal ringtoss. Request lock.
