Hover the mouse pointer over a warning, error stripe or just some section on the scroll bar outside of the scroll box. PyCharm Edu shows the source code fragment annotated with the warning/error messages.
This helps viewing the context a marker applies to, and the source code outside of the editor visible area.
This behavior is enabled by default.
