The top Screen Select Toolbar provides buttons for choosing a specific display screen.  The left edge Signal Control Toolbar provides buttons to change the display characteristics.  The Session Control Toolbar at the bottom of your screen provides controls for specifying tasks, recording data, marking events in the data, and for invoking various screen features such as screen freeze and sweep reset.  The Session Status Bar, located below the Session Control Bar, indicates elapsed and remaining times for both the current task and the entire session.  The Task Progress Bar located above the Session Control Bar indicates progress through one or more preset timed task intervals.  It is a graphical representation of the numbers in the Session Status Bar.

WITHIN SESSION MANAGEMENT - OPERATING THE MASTER SCREEN

The Main Screen is surrounded by Toolbars.
In this system, almost all your session controls are found on  toolbars.

Some controls are found directly on the toolbar (like adjusting Gain and Offset).
Other controls are indirect, popped up in a window by clicking on an icon in a toolbar.

You can show or hide toolbars by seleting or deselecting them at sart-up on the View menu.
