The order in which you select fixtures is significant in controlling how fanning and effects are applied to them; see Fanning and Effects. For example, applying a fan or effect after selecting fixtures 1-5 can appear different than if you selected fixtures 1 + 3 + 2 + 4 + 5.
The selection order is relevant during programming, and is recorded as part of groups, but it is not recorded in palettes, cues or scenes.
Because the console records the selection order as part of groups, you can select the group and use the Next and Back keys to subselect each fixture in a particular order. By controlling the selection order when you record the group, you can then work through a series of fixtures in the order they are physically positioned in the rig, instead of in numerical order.
You can change the selection order of fixtures in predefined ways. The Reverse, Shuffle, and Reorder buttons are on the Select Toolbar and Fanning Toolbar:
Main Toolbar → Select : open the Select Toolbar.
Reverse: reverses the selection sequence, so that the last is first and the first is last. For example, the fixture selection 1-5 becomes 5-1.
Shuffle: randomises the selection order of the current selection. For example, the fixture selection 1-5 becomes 3 + 5 + 2 + 1 + 4.
Reorder: sorts the selection order to match the User Number order. For example, the fixture selection 3 + 5 + 2 + 1 + 4 becomes 1-5.
The Reverse, Shuffle, and Reorder buttons can also be found on the Fanning Toolbar, which you can open by pressing and holding the Fan key. See Fanning.
