adding a BBC help button on top of posting - and toggling additional items

[bouton]

two questions

1.How do I add a help button, like a question mark or something, some where near the top of the post page
which would point to http://docs.simplemachines.org/index.php?board=22.0;sort=subject

2. How do I toggle the additional options at the bottom of the post page to always show all options?

thanks
