How can I jump to from one page to another?

Is there a way to jump to a page?

Only could you input a number in the page form on the menu bar bottom within the limits of the whole pages and then key "Enter", it will jump to the relevant page you want.

1. On the area down-right, there is a page turning menu. input a number;
2. The number is within the limits of the whole page;
3. Click "Enter", it will jump to the customized page.

PS: If the pages is vast, it provides so much convenience!
