Without having your code, this is just an example:
on *:dialog:dialog_name:sclick:1:{
did -k $+ $iif($did(1).state,-c,-u) $dname 2-5 $did(1).sel
}
When you click on an item in the first column (I used ID 1), then the same lines in columns 2 - 5 are highlighted automatically
If you need more assistance, post your dialog code and I'll be happy to help.
