What are the different punctuation in Quran?

I would like to know how many punctuations are there and their respective action (i.e. stop for a while or don't stop at this point of sentence) that come in Quran. For example, I know of one punctuation(not the exact letter) that is meant to be - the reader should not stop at this point while reading because that would make the sentence change it's meaning and could be totally opposite. Please let me know.
