Kevin, thank you for the response. I did a grep on the whole tree  
right after I sent that message out and noticed the %ARGS in the  
Ticket/Element and Element/ directories and have been trying to muddle  
my way through them.

In case you are curious: I am trying to modify the display of a custom  
field value. Unfortunately, there seems to be no Callback for each  
specific value in Elements/ShowCustomFields, so I may do a local copy  
of that whole script to make my changes, rather than attempt a  
Callback (using say MassageCustomFields). Or I could add code to  
ShowCustomFields to introduce a new Callback: MassageCustomFieldValue.  
Being an amateur, I am not necessarily sure which direction I should  
take.
