Yes, it does. Go to View>Toolbars and make put a checkmark on the
Formatting toolbar. This will add format shortcuts to your toolbar. At the
end of the toolbar you will see ">>", which will open a drop-down menu,
click that and then click "Add or remove buttons", a second drop-down menu
will appear, then place a checkmark beside "Show All". Click anywhere on
the blank document and the drop-downs will go away. You should now have a
symbol that looks like a backwards letter P, this icon toggles the reveal
codes on and off. Hope this makes sense.
