When you hover your mouse over a post, a couple of buttons pop up. One of those is quote. It pasts the post into the reply box down below, and to change the quote you just click inside the darker grey box that the quote appears in. You can edit quotes to your hearts content.

This way you can also cut out stuff from really long posts that don't have anything to do with what you are replying to; say Phantom wrote something that is five paragraphs long and you just wanted to address something in one paragraph. You can cut out everything you don't need. This stops your post from getting super long as well, which is annoying when trying to read through a forum.
