Restore (Choice)

If a window can be minimized, provide a Restore choice in the window icon's window menu to allow the user to return the window from the minimized state to its previous size and position.

If a window can be maximized, provide a Restore choice to allow the user to return the window from the maximized state to its previous size and position.

If a window is maximized and the user chooses Restore from the window menu, restore the window to the size and position it had before it was maximized.

If a window is minimized (iconified) and the user chooses Restore from the window icon's window menu, restore the window to the size and position it had before it was minimized.

If a primary window is minimized and the user invokes Restore, restore all of the secondary windows that the application has not closed.

Do not make the Restore choice available when the window is neither minimized nor maximized.

Provide a restore button that implements the Restore choice on the title bar when the window is currently maximized.

Replace the restore button with a maximize button in the title bar after a window has been restored to a state other than maximized.

Replace the maximize button with a restore button in the title bar when the window has been maximized.

Make the Restore choice the default action associated with the window icon. If the window was maximized before it was minimized, restore it to its maximized state.

Allow the user to invoke the default action of the window icon by double-clicking the SELECT button on it, or by pressing Enter or keypadEnter when it has focus.
