Controls are the familiar elements in windows such as buttons, check boxes, icons, fields and sliders. These are the elements that contain the functionality of the window. When the user presses a button or drags a slider they expect something to happen. Commands and scripts can be attached to the controls to be executed on user actions. Attaching will be described in a later section.

For a list of the controls that are available, see the “UI: Controls” section of the Command List by Function.
