SNEAK

Usage: sneak
 
Used for sneaking (moving in and out of rooms without anyone knowing). The 
sneak command will toggle on and off your ability to sneak.
 
The chances of a succesful sneak depend on the terrain and the number of 
people you are trying to hide from. You must be on foot: sneaking on horseback
is impossible. It is impossible to sneak successfully when you are fleeing a 
room. Hobbits, Kender, Gremlins and Elves (to a lesser extent) sneak well, 
Dwarves not so well, and Trolls and Giants are totally inept at sneaking.
 
After sneaking succesful, you are hidden from the people in the room, but if 
they look for you they will find you instantly.
 
You move slower when sneaking.
