For clarity suggest that in section - Log out or switch users - the
reference to system menu be followed by the appropriate symbol as in
unity-menu-bar-intro Status menus par 7; as following the link also
entails opening the "List of status menus and what they do"
but adds nothing to the action being suggested.
If it is required that additional information is beneficial then a
with specific link to unity-menu-bar-intro with reference to Status
menus par 7 could be added.
