From my little book of grammar

Separate words, phrases or clauses in a list
Before and after a phrase or clause in apposition
Separate ?sentence adverbs?
Mark off the person addressed
Bracket off insertions or afterthoughts
Mark off interjections
Before tagging on clauses like ?don?t you??
Mark off a participial phrase
Mark off adverbial clauses
Mark off an adjectival clause which merely comments but does not limit or define
