How can I copy the code examples in postings in community / UA?

I'd like to take advantage of code examples contained in postings that appear in various places in the Unity site(s). However, if I highlight and copy the code, I get triple spacing, line numbers, etc. I tried to do my due diligence by searching this site, but couldn't find anything on the subject. Could someone tell me how to do that? (And, as an aside, I'd recommend adding that as one of the FAQs for people new to either Unity or use of the same code snippet capability on other sites.) Thanks in advance.
