Toolbox Window
The Toolbox window contains a list of controls you can add to an operator interface. Controls include knobs, slides, switches, rings, text controls, and labels. Operator interface controls resemble the controls that appear on the front panel of an instrument. An operator interface allows a user to change step parameters when a project is in operator mode. Use the Toolbox window with the Operator Interface view to create an operator interface. Select a control in the Toolbox window and drag the control to the Operator Interface view to add the control to the operator interface.
