I've seen pages like this where they have links to answers in the description. I've noticed this works by adding a number to the end of the URL (i.e, 12345). How do I find this number so I can link things? (I know how to do it for my answers, but I'm wondering about answers in general.)
If you look at the very bottom of the answer, on the left side, you will see a small "share" button. Clicking this will display a URL that links directly the answer. This URL will contain the answer's ID number, followed by your user ID number.
