This topic came up again and here's a non-video description of the process of quoting individual sections - because the software changed at some point after 2013, and it's much MUCH easier to quote small sections now!
1. Be sure you understand (from the short video in the first post above) about not messing with the information inside the two (starting and ending) sets of brackets [...]
2. If you have not started your reply and you want to quote only a small section or a sentence from someone's longer post, use your mouse or finger to hold, drag, and highlight the section you want to quote. A small "Reply" balloon should appear at the end of the highlighted section. Click on it. Your post is now started below. You can enter text before and/or after the quote.
3. If you already started your reply and want to insert a quote, first make sure that your cursor is located where you want to insert, before going back up to the original post and doing the drag/highlight/Reply thing.
4. Do this as many times as you like. If you move things around, maintain the integrity of the brackets. And, as a matter of forum etiquette, don't be tempted to change anything between the brackets - it's not your text.
