Subject: Case menu - obtain the first conditions?

Hi.

Consider I have a case menu like this.

def enter_menu
  case @i
  when 'list_cars','lc'
    list_cars
  when 'list_horses','lh'
    list_horses
  when 'list_plants','lp
    list_plants
  when 'help'
    show_help
  end
end

Now, inside the method show_help, I would like to
call the FIRST entry on each case menu.

I.e: list_cars list_horses and list_plants

Is there a way to do this easily?

The actual case menu is very very long, with multiple aliases.
But the main name of every when entry is always the first entry.

In other words I would need a way to programmatically access the
first option of every when clause.
