Shortcut key also works:
My shortcut key for nodeeditor:

Ctrl+Alt+N moi.ui.createDialog( 'nodeeditor/index.html', 'resizeable,defaultWidth:680,defaultHeight:420', moi.ui.mainWindow )

#######

Also made a copy of index.html named indexFR.html, with FR instead of EN the only change, also placed in nodeeditor subdirectory.

My new test shortcut key for French is:

Ctrl+Alt+Z moi.ui.createDialog( 'nodeeditor/indexFR.html', 'resizeable,defaultWidth:680,defaultHeight:420', moi.ui.mainWindow )

Hope some of this helps.
