Editor shortcuts will not work if you launch the editor with a non-Latin-based language (ex. Russian, Chinese). The editor must be closed and restarted with English (or possibly any Latin alphabet-based language) for shortcuts to work again.
Results: Shortcut keys no longer work in the editor
Expected: Shortcut keys to still work even when launching the editor with a different language.
