When your player is surrounded by items and you can not 
throw down any more items without moving, throw an item 
from your belt. It will fall on the ground two squares from 
your player, but the item will still be on your belt. 
You can pick it up and have two. This can be done as many 
times as needed, with any item that is on your belt. 
This is especially useful with elixirs (spectral) 
and potions of full rejuvenation when in the lower levels.
