Your code seems fine to me. click to select, ctrl+click to de-select (on a PC). Probably cmd+click on a Mac.

To unselect a selected entry in a List Box(), simply hold down the CNTL key and then click on the selected entry. It will then change to unselected.

Concerning your JSL....you seem to be guessing at the syntax to use. What you need to do to find out what messages are available to a given object(in this case a List Box) is to open the Scripting Index, and go to the entry for the specific object you are using.

There you will see that the Set Selected message is used for both selecting and unselecting Also, the Set Selection message uses the Index for the selected so you need to use the Get Selected Index rather than the Get Selected
