Syntax: look
look <object/character/keyword>
look 2.<object/character/keyword>
look <direction>
look all
look in <container/corpse>
look here <item/description>
look inv <item/description>
look item <keyword>
glance <player> OR look equip <player>
examine <player> OR look desc <player>

LOOK <OBJECT/CHARACTER/KEYWORD> looks at something and sees what you can see.
If the object is a container it will also show you what is inside.

LOOK DIRECTION lets you find hidden doors and secret rooms. LOOK ALL will
look in all directions and show you what is there.

LOOK IN <CONTAINER/CORPSE> will show you only what is inside the object.

LOOK HERE <ITEM/DESCRIPTION> will only look at things that are in the room,
not things you are carrying or wearing.

LOOK INV <ITEM/DESCRIPTION> will only look at things that you are carrying,
not things that are in the room.

LOOK ITEM <KEYWORD> will look for an object with the keyword and ignore all
creatures or players that may have that same keyword.

GLANCE <PLAYER> is equivalent to LOOK EQUIP <PLAYER> and will show you what
someone is wearing.

EXAMINE <PLAYER> is equivalent to LOOK DESC <PLAYER> and will only show you
the description of a player, not what they are wearing.

You have the option of tagging the Nth type of something. For example:

look 3.axe looks at the third axe in inventory or in the room.
look 2. looks at the second creature in the room; if there aren't
that many bodies in the room, it looks at the second item in
inventory.

My suggestion would be to make an alias for exa to be look here.
