Dynamic-value variables are called Local Variables in the Global Variables dialog. They contain device-related and project-related information that can change during project execution. For example, the device orientation variables will change according to how the end user is currently holding the device (see the description of the device orientation variables below).
The variables that contain information about the current control (see below) are particularly useful because they can be used to refer to different aspects of the control and the node being currently processed. Being able to identify the current control and node enables conditional processing. For example, the $MT_ControlNode variable can be used to test which node is the current node at a given time during project execution, and locate another node on this basis. The $MT_ControlValue variable holds the content of the node associated with the current control.
