Ok good. That was my understanding as well.

Yes. So far I have tested it with the nosy list (multilink to users),
dependson list (multilink to issues) and topic (multilink to
keywords). So I'm assuming it will work with other multilinks as well.

It is url encoded to:

   keyword=5%2C6%2C8&nosy=1%2C3

which is keyword=5,6,8 nosy=1,3.
