Show Keywords in Listing (RT2)

I am trying to modify the queue listing in RT2 to display selected keywords. I’ve been playing with the QueueListing settings in

   { Header => 'A Keyword',
    TicketAttribute => ???

I don’t know what the correct syntax is to set TicketAttribute in order to display a specific keyword select. I have tried QueueObj->KeywordSelects and KeywordsObj(Id) (substituting integers for Id). An example of a returned value displayed using QueueObj->KeywordSelects is “RT::KeywordSelects=HASH(0x8d599ec)”.

Any help will be appreciated.

Thank you,
