You can specify objects (things, players, exits, and rooms) by name
if they're in your inventory or in the same room as you are. You need
only type enough letters of the name to be unambiguous. You can also
specify objects anywhere by their dbref numbers, in the form #(number).
Players in other rooms may be specified in the form *(player name),
groups may be specified in the form of +(groupname). The word 'me' can
be used for yourself, and 'here' may be used for the room you're in.
