Great list, thanks.
Took the liberty to take your document and translate it into spanish, even though there's no official translation yet, changing those shortcuts that are usually different in spanish (e.g CTRL+A is CTRL+E in spanish versions) and freely translating those new elements we still don't know how MS will translate (e.g Charms Bar)

Full credits to you, of course.
