## Application Information

In windowed mode, the title bar shows information about the running application and current project.

The information varies with the software and may include:

- The name of the currently loaded project file.
- The T3RRA application name, such as **T3RRA Cutta 3**, **T3RRA Ditch 3**, **T3RRA Plane 3**, **T3RRA Survey 3** or **T3RRA Apply 3**.
- The installed software version.

Use **Full Scrn** to toggle between full-screen and windowed operation.

Full-screen mode maximises the display area available to T3RRA. Use windowed mode when you also need another application or a Windows function.

With a keyboard connected, **F11** also switches between full-screen and windowed modes.

## Settings

Open **Settings** to review or configure the application.

Before starting work, check that the software configuration is correct for the machine, implement, project and GNSS system in use.

Refer to the **Settings** chapter for the available settings and their functions.

## Open Manual

Use **Open Manual** to access the T3RRA Operator’s Manual.

The first download requires an internet connection.
