Where is the Preview Feature Mentioned on Page 674 of the Mac Manual?

Trying to find it:

The program interface doesn’t know either:

I think this is what is referred to, found in Compile.

Yes, though that one is just where you would get a sense for how the Format is designed to look in a passive way. There is another button, labelled Preview, in the actual area of the user interface that this section of the manual is documenting. It has its own subsection, §24.20.1. I’ll throw a cross-ref to figure 24.16 in there as well, but this whole section is meant to be cohesive.

P.S. The Mac’s menu search tool does only that, it does not dig through the entire interface and allow one to jump straight to buttons, labels or panels by name. That would be pretty neat (though probably entirely impractical).
