history.back(); //Go to the previous page history.forward(); //Go to the next page in the stack history.go(index); //Where index could be 1, -1, 6, etc. OR window.history.back(); //Go to the previous page window.history.forward(); //Go to the next page in the stack window.history.go(index); //Where index could be 1, -1, 6, etc.
