Just add a new page in confluence and add the following code in "wiki markup"

Bold Testing

Now toggle to "Rch Text" and you will see that the words Bold testing have turned to Bold type. Now add the following code in wiki markup and try toggling to Rich text,

{toc-zone:type=list|location=top}
Bold Testing{toc-zone}

You will notice that the "Rich text" editor no longer shows the words as Bold, but infact just shows the text along with star signs.

The same holds true for

{zone-template-instance}

macro. Try it out!
