LOOK

For studying your surroundings or looking at items, creatures, etc.

Examples:
  > look
  > look at nazgul         (or l nazgul)
  > look in bag
  > look south             (or look s or even l s)
  > look 2.map
  > look in 2.corpse
  > look inv.2.sword       (look at the 2nd sword in inventory)

Note that if you look at a container you will not see its contents but its description. Therefore look corpse will not show the inventory of the corpse.

To see what is inside a container (e.g. corpse, pouch, …) use examine <container> or look in <container>.

look around will search your surrounding rooms for light or smoke.
