good god, this is the most player-hostile interface i've ever seen. this looks like a joke about computer games from a 1990s console game magazine. this entire list of commands should be collapsed into two: use and equip.

if you use a useable item (scrolls, potions, wands, books, food) it uses it. if you equip an equippable item (armor, ring, amulet, armor, weapon) it flips its "currently equipped" state to on or off.
