Most control plug-ins have a set of common properties:

• Field Identifier: Used by the control client applications to identify the editable item in the scene. Only English characters (A-Z, a-z), numeric digits (0-1), dot ( . ) and dash ( - ) are allowed. When a dot is used in the identifier, e.g. "1.score", it means this is a sub-field. Multi-level sub-field is allowed. When making templates for Viz Trio, this should be a numeric value, starting at 1. The numbers are used to create the tab-order between the editable items. For Viz Pilot and Viz Ticker, this can also be a descriptive text string.

• Description: Describes the tab field or editable object. This is used as a description for the items when used in the control clients.

• Show only in Expert Mode: Hides the tab-field properties for the user if Expert Mode is enabled in Viz Trio. For more information, read about Viz Trio’s macro commands, and the command set_expert_mode_enabled.
