As mentioned, Shift-Down will do. (Also, while holding an item, Shift will use if the item is usable, throw otherwise. Usable items can be put down with Shift-Down as well).
These controls are actually explained in the LD levels (door on the right in the very first screen of the game), which you're encouraged to play first!
