How do you pick items up to move them around? I saw a video of someone putting buckets on people's heads, so the ability must still be there, but it used to be on Z and that's otherwise bound now.

Also, I swear I did this when I first started the game, but I can't now- how do you spin the camera so you can see the front of your character? It's always been done by holding the middle mouse button, but at the moment it just spins me around. The fact my graphics settings are sort of low wouldn't screw with this, right?

For whatever reason, neither of these things appears to show up in the controls. :\

On keyboard hold e to grab.

Rotating the camera will also rotate your character if you have weapons drawn (confused me something awful at first!)
