6. Quickly jump to the top of the page by clicking anywhere on the menu bar. If you're already at the top, you'll go to the bottom. If you've just quoted someone, you'll go back to their post so you can quote them again.
7. Double-click on the left-hand side of the page to go back. Double-click on the right-hand side to move one page forward.
8. When you add formatting to a post, you'll notice special tags being added, like [b]bold[/b]. They're pretty easy to understand, so you might prefer to type them out yourself. That way you can style a post without interrupting your flow.
9. You can remove tags by hand, or select some text and click on the style you want to remove.
10. Keyboard shortcuts can make commenting easier. Ctrl+Enter submits your post, while many of the formatting features also have shortcuts. Hover over them with your mouse to find out what they are.
