Is there a way to "Cancel the Mask View" ?

Hello:                                                                                                                    Level: Newbie  OS: Win7 64bit   Ps: CS6

I am working on a tut so that I can (try to) learn about Masks.

But for the life of me I cannot find info on what it means to ... cancel the Mask view.

( Here's the tut link ... http://rgbjam.com/tutorials/creating-a-pencil-in-photoshop )

This is a pic from the tut. See in the top layer (Body) how the down arrow, folder and the link icons are grayed out?

Well, this is what the tut says to do ....

I cannot for the life of me figure out how to cancel the mask view.

I have Shift + Clicked the masks thumbnail but that doesn't give me the result like the picture above shows and I've tried the Alt + Click but that doesn't do it either.

Any ideas what the author means by this ... Cancel Mask View ... ??

As always your help is whole heartedly appreciated
