How to get the Visual editor as a pop-up?

System

I am trying to use VisualFormat by creating buttons each
place it's specified, so that the textarea looks like a "regular" one, but clicking the button placed next to it will pop up a window with the VisualFormat editor within it.

The string I am using for this is:

<textarea cols="80" rows="20" external-editor="VisualFormat" external-editor-inline="f" wrap="virtual" />

but I am not getting any buttons. Is ths the right way to do this?
