Names of all the interface elements?

In iMovie help, it will say such things as “in the project browser” or “in the clip browser” but it does not identify these areas of the interface. I looked at the opening screens of iMovie help, and I cannot find a section where the various interface elements are identified.

It would be nice if, when it mentioned a certain interface element, you could click on that text and instantly see an image of the element and where it is located, but I have submitted a suggestion to Apple.

In the meantime, is there an area in iMovie help where it identifies the names of all the interface elements?
