I replaced the
<<<scheme='+theme+'&lang='+language+'', 'resizeable,defaultWidth:870,defaultHeight:480',moi.ui.mainWindow );>>>
portion of the shortcut key with:

<<<scheme=Light', 'resizeable,defaultWidth:870,defaultHeight:480', moi.ui.mainWindow );>>>

An now the resizable portion of the shortcut key works.

Since I do not know what I am doing, perhaps MO can comment. :-)

ps, resizable is spelled resizeable, in the UK, as far as I can determine :-)
(computing, formal, UK) Alternative form of resizable.
