Permanent Menu Changes
If you want to make the new menu positions permanent, use the Save
Settings option (from the toolbar or the File menu) to save your
settings.
If you change your mind and want to return the menus to their original
positions, select the Reset Toolbars option from the View
menu. A confirmation dialog will open, asking if you really want to discard the
changes you have made. If you select Yes, the menus will return to
their original configuration. If have modified also your toolbars, this option
will reset them, too.
