All Event Actions have a choice of THEN or NEVER. This is simply a diagnostic tool for disabling individual Actions in an Event. If you want to temporarily stop an Action from being included in an Event select NEVER. Here is an Event with three Actions

By changing one of the actions to NEVER, it will not be executed.

The Event will then only turn Device1 and Device3 On, it will skip the Action controlling Device2.

THEN means perform the Action.
NEVER means don't perform the Action.
This is not conditional, nor can it be set by another Event.
While some may think that "DISABLED" might be a better term, this still goes with HomeSeer's use of plain English descriptors.
THEN do this or NEVER do this is equivalent to THEN do this or DON'T do this. THEN do this or DISABLED do this properly describes the Action, but is not in plain English.
