Thanks much for the quick replies snowman and neone6.
Unfortunately, I find no help in any of those links.
I don't have Skin Studio nor time or inclination to create skins myself (tho' it would be very cool and frustratingly fun, I'll bet! - and I much admire and appreciate those who have and do!) - I'd just like to know what each of those Listed Items actually is ... So I can try to 'fix' a couple issues here in my favorite skin.
"Or..... do it the hardcore way: Download a/any skin. Alter different parts of the skin and see what does what. That's how I learned to skin WB, some 10 years ago."

..It looks as tho' that's what I'll have to do... I was hoping for a less 'experimental' approach, but - ok... I'll see then.
Thanks again for the offered help and your kind replies guys - much appreciated. 
Best regards,
Tia
