Display a pop-up menu in a window using the PopMenu function to identify the menu and location.
If the menu is currently associated with the window, you can simply call the PopMenu function.
m_appl.m_help.PopMenu(PointerX(), PointerY())
If the menu is not already associated with the window, first create an instance of the menu.
m_new mymenu mymenu = create m_new mymenu.m_file.PopMenu(PointerX(), PointerY())
