4.0.2 Using the Display Controls
Each display has a display control associated with it. A Display Control Window is a panel or window with menus, buttons, sliders, and other widgets to control a display. When a display is first created its display control is added to the Dashboard or pops up in a separate window depending on your configuration. The control also has a legend shown in the View Window's legend panel.
The Display Control Window
The control window is used to change the properties of the display. Each display type may have a different set of widgets in the control window. For our dewpoint display, the control looks like this:

Display Control Menus
In addition to the widgets, each display control has a set of menus associated with it that allow you to change the behavior of the control, change some of the display characteristics, or get help on using the control.

The menus can be accessed from the menu bar in the control window:
