@action

The @action command is used to open a new exit on an object. 
The exit's destination can be a room ID, 'home', or 'nowhere'. 
Many synonyms for the exit's name can be provided by separating 
the synonyms by semicolons. The destination can later be changed 
using the @link command. NOTE: The object must be set EXPERT for 
the exit to be usable.

Usage:

@action push button;press button = device : nowhere
@action wand magic wand;wave wand = magic wand : #500
