Groups help reduce script steps By creating groups of units, you can control several devices with a single XTension script or button. The DEMO database includes a group named “All Outside Lights” which refers to all of the commands for the outside lights of the demo house. Any command to the group name will cause XTension to issue the same command to each of the members of the group individually. Thus you can turn them all ON or OFF with a single : “turnon “All Outside Lights” Groups are also useful when you want to create a List of items of special interest, such as "All Motion Sensors". For example, when you are modifying the scripts of a group of related units, you may want to create a limited List window in order to reduce the amount of scrolling you might have to do from the Master List window. The sequential order of the units in any Group is important: With versions of XTension after 1.7, it is possible to 'drag around' the units which are in a Group, thus 'ordering' them such that you can specify the order in which they will be 'commanded' whenever you issue a command to the entire 'group'.
