Different lights may have different shape abilities, such as gobos, edge, motorized shutters or zoom. Only the abilities specific to the selected light are added to the tool bar.
Wheels: Access
options for gobos, shutter, lens focus, rotation and other effects. These
options normally appear on a secondary tool bar, called the Wheel
Bank. Wheel buttons 
provide quick access to named gobos or standard zoom values. Holding
down Shift 
and one of the Wheel buttons
will force default values (i.e., clear the gobo) and with some attributes
successive presses will take the attribute to its extents.
Advanced: Allows you
to lock or ‘park’ the shape attributes of selected lights. Also
allows you to release recent changes, or to set a light its default shape
(typically open). Shape attribute values that are locked are not
recorded into Memories or Cues. Further advanced options, including
Desk Lock
and Knockout, are
discussed under Advanced
Attribute Control.
Libraries: Recall
custom shapes saved using RECORD>Library>Shape. Shape Libraries
are specific to the lights in use when recording the shape. Updating a
Library will automatically update any Cues and Memories that use it.
Effects:
Shows any currently active effects on a secondary tool bar. Intensity
must be higher than zero percent, for effects to be visible. Touching
the New Effect icon displays a list of available Shape effects.
