Move objects above or below each other

- [Instructor] Every object on your page is in a stack.…It's kind of like each object is a separate piece of paper…in your document,…and you can move them above and below each other.…Now, some people call this the Z order,…like each object has an X and a Y coordinate…on the page, right?…But it also has a Z coordinate,…and that describes which object is on top of which.…Now, here in this interactive document…from the exercise files folder,…I'm going to change the stacking order,…or the Z order, of some frames,…and those frames are on the first page of the document.…

So I'll open my Pages panel,…double-click on the first page,…and then close my Pages panel again.…Now I'd like to select this image here,…so I click once on it.…But you'll see that I didn't select the image.…I selected this other frame…that's sitting on top of the image.…So how can I select what's behind that,…like that image back there?…Well, you can select through one object…to an object behind it…by holding down the Command key on the Mac…or the Control key on Windows…
