The menu bar of the main display contains the menus View, Actions, and Help. If you accessed AMU as a standalone system (not through SPM), a fourth menu, File, is visible as well. When the platform is closed, only the File and Help menus are visible.
On the right side of the menu bar there is an indicator of the exclusive control mode. You can take or relinquish exclusive control by left clicking the Off-On indicator or the label.
