The window Menu, sometimes called the system Menu, is used to display the list of window actions. All actions possible for a window should be displayed in the window Menu, since keyboard-only users interact with the window manager through this Menu.
The window Menu button must be located in the upper-left corner of
the window. Double-clicking the window Menu button must close the
window. Pressing
or
must activate the window Menu button for the
window with the focus. The illustration on this reference page shows
a posted window Menu.
A primary window Menu must have the following selections in the order listed:
A secondary window Menu must have the following selections in the order listed: Move, Size, and Close. A secondary window Menu can include Restore above Move, Maximize below Size, and Lower above Close, but the lower option on a secondary window lowers all the windows secondary to that window's primary window. A secondary window Menu should not include Restore if it does not include Maximize. A secondary window must not include an entry for Minimize.
A secondary window resulting from a Menu being torn off must have the following entries in the order listed: Move, Lower, and Close. It must not include entries for Restore, Size, Minimize, or Maximize.
