Finding anything in Word's Help is a bit of a crap shoot because it uses
Bing as a search engine. <g> You're better off just googling for an answer.
That said, wrt the actual Help file, there is nothing like an index, but
there is a button on the toolbar for Show Table of Contents, and this might
be helpful. Select the Customizing heading, and one of the topics is "Change
the appearance of Office programs." Click on that topic, and it includes
"Change the Office color scheme."
The problem with searching is that there isn't much Help actually built into
Office, so if you don't search online but use just the local Help file, the
chances of getting an answer to any very abstruse question are small. But if
you do enable online search, the first few hits tend to be time-consuming
tutorials (often videos) rather than the simple Help topics you remember
from earlier versions. It actually used to be possible to access the entire
Word 2003 Help file online; now, alas, the URL redirects to a generic search
page. <sigh> There's what purports to be a replacement at
http://office.microsoft.com/en-us/word-help/CL010072934.aspx, but it's not
the same thing at all.
