Moving on to page two

I'm not exactly sure how to word this or if my question will make sense...When I go to open a thread that has a page one and two and I want to read the posts after mine I get to the end of the page but don't know how to continue on to page two without going out of the post and beginning again by clicking the number 2 (indicating page. ) Is there an easier way if I already have the thread open?
