[TxMt] secret Help menu

[kumar mcmillan]

wow, accidentally pressed the Help key while typing in TextMate and 
found a menu with the following options:

Dictionary Search
Google Search
Thesaurus Search
Wikipedia Search
Yahoo Search	

Upon selecting an item, TextMate passes the current word under the 
cursor to the said service.  very nice.  I haven't seen this in other 
programs -- is this an OS X thing?  Or better yet ... Is there a plist 
somewhere in TextMate to add to the list?
