When do I use - Hyphens? What's the difference between a long – hyphen, and a short - hyphen? When do I use italics? In speech 'Is it okay?' to do this. That is, use lowercase after a full stop, exclamation mark or question mark. Do I indent the first sentence in a chapter? In what circumstance is it correct to put a comma in front of a name, Stranger? When do I use a semi-colon; in place of a comma? Thank you! Please use examples in your answers. If I think of more of these that bother me I'll post below. N.B. I didn't use the punctuation above in circumstances in which I thought they belonged. I placed them in each sentence merely to accentuate what I was asking about.
