The menu object is supported since WRT
1.0.
The menu object is a built-in JavaScript object
in the widget engine. It is extended from the window object
to provide widget-specific APIs for manipulating widget's options menu and
softkeys.
The menu object can be accessed via the window
object window.menu or just simply menu.
Thus, in the WRT environment, the term menu is a reserved
keyword and should not be used as a user-defined global variable name for
other type of objects.
A widget's options menu can be constructed using the menu object.
The options menu is automatically associated with the device's left softkey
and it cannot be reassigned to associate with another softkey (for example,
the right softkey). The label of the options menu (the left softkey) is the
system-defined term in the current used system language (for example, Options for
English). Thus, the left softkey label cannot be changed.
