Search
From MUME
Search is a thief skill that allows you to search for otherwise hidden people, exits and objects in the room.
With a given direction, you search for a secret door in that way. The better you are, the more likely you will find something (if there is anything to discover).
Also, type "search" with no arguments to look for hidden objects.
Type "search <effort>" (where <effort> is one of quickly, fast, normally, carefully, thoroughly) to look for hidden people. Your chances of success will depend on your eyesight, hearing and sense of smell, as well as on your search skill.
Examples:
> search up searches for a hidden exit upwards > search searches for hidden items > search q searches quickly for hidden beings in the room
