Zbrush noob question

Hello, I am new to Zbrush and learning myself by reading a book.
In the book I am studying, the author has shown that mannequin in above image to become like following image:

And he try to scale that sphere smaller, then put it into the face rectangle.
But I do not know how to make that human mannequin transparent temporarily like 2nd image.

How can I do this? is there a way to make something transparent like that? the author doesn’t mention about it in the book.

There are Tansparency and Ghost buttons beside your viewport window.
