Excel Object Browser

Does anyone understand the Object Browser in MS Excel?
 
Two questions: 
 
1.)  My understanding is that the Applicaiton object is the highest object in the hierarchy, yet in the object browser, there are multiple classes shown at the same level as Application  - such as Addins, Adjustments, etc.  Why doesn't the browser work like a tree?
 
2.)  What is the <globals> class?  Is it in fact a class?
 
Thanks,
Eric

I will answer your question by not answering your question. If you want to look at the Excel object model, here is what I suggest. With a standard install of office, go to C:\program files\Microsoft Office\OFFICE11\1033 and open VBAXL10.chm. That is the best source that I have found for the Excel object model.

From the Object Browser help:

"Displays all of the available classes in the library or project selected in the Project/Libraries box. If there is code written for a class, that class appears in bold. The list always begins with <globals>, a list of globally accessible members."
