# Outline view

The Outline view displays an outline of a structured C/C++ file that is currently open in the editor area, by listing the structural elements.

The Outline view shows the following elements in the source file in the order in which they occur:

- Class
- Namespace
- Include
- Enum
- Enumerator
- Field private
- Field protected
- Field public
- Include
- Method private
- Method protected
- Method public
- Struct
- Typedef
- Union
- Variable
- Function
- Macro Definition

You can also sort the list alphabetically. When you select an element in the Outline view, the C/C++ editor highlights both the selected item and the marker bar (left margin). For example, to move to the start of main() in the C/C++ editor, click `main()` in the Outline view.

For more information about the marker bar, see Workbench User Guide > Reference > User interface information > Views and editors > Editor area.
