I have two keywords fields, called 'publish' and 'delete'
each have three values, all can be selected..
so 'publish' could be 'test, review, live' one or all may be selected.
when a user wants to remove this doc from any of above they use 'delete'
again the values will be the same.
if they select say 'test' in the delete keyword list, I want it to be removed from the 'publish' list and added to the 'delete' list, again one or more may be selected.
