Inventory list (i)

       Displays a list of objects being carried but not equipped.  You
       can carry up to 23 different items, not counting those in your
       equipment.  Often, many identical objects can be "stacked" into
       a "pile" which will count as a single item.  This is always
       true of things like potions, scrolls, and food, but you may have
       to set options to allow wands, staves, and other such objects to
       stack.  Each object has a weight, and if you carry more objects
       than your strength permits, you will begin to slow down.
