Is there a Special Page (or magic word?) that displays a table of the current interwiki/interlanguage prefixes for users on a MediaWiki installation?
No.
But if you are WikiAdmin, you can install this stable extension http://www.mediawiki.org/wiki/Extension:SpecialInterwiki which adds a new Special Page listing all prefixes for all users and allowing to modify/add for users with special rights.
