The Control Panel   This window 'floats' above all other XTension windows when it is present. The left part of this panel always shows the state of the currently selected unit. If no unit is selected in any other window, the left part of this panel will be empty. Note that if any unit is selected in any View or List, then the "Last Event" time will be for that selected unit. If there is no unit selected, then this time is the last event time of any type. From this part of the panel you can change the state of any unit by the ON/OFF switch, or if the unit is 'dimmable', you can set the level with the slider switch. If the slider is 'grayed' out, it means that the unit is not 'dimmable'. If XTension indicates that the unit is already ON and you want to send another ON command : Shift-Click the toggle switch ! The icon to the right of the slider is the 'Blocking' control. It displays the 'Blocked/Unblocked' status of the currently selected unit. ( see the Blocking chapter for more ) The right hand side of the panel shows the current time and the time of the last event. (XTension uses the Macintosh system clock.) You can push the 'reduce' button to hide this side. Below these are 5 icons which allow you to add a new unit, create a new 'group', choose items to be in a list or view, edit the current item, or delete the selected item. The New Unit button will prompt you to add a new unit to the database, and the New Group button will let you create a new named group of other database items. If you have selected a unit in any list/view, and if you hold down the option key when you select New Unit, this will Clone the selected unit and allow you to enter a name and address for the new unit. The Choose button is used in several cases to choose or select the items in a List or View. The Edit button will bring up the Edit Unit or Group dialogs. They will only work when you have a current unit selected in one of the Views or Lists. The Delete button will delete the selected item from the database if you are viewing the Master List. Otherwise, it will simply remove the selected item from the front window, whether it's a List or a View. ( If you just want to remove an item from a list or view other than the Master List, then just drag the item to some illogical place on the desktop. )
