Which hook to use? Changing Thread display

[Zurvan]

Hi

I'm working on a mod that requires a text box, an additional button, and a few other things, to be shown just above the Quick Reply box in every thread. Some of this info has to come from the database, so we need to add something to the php.

Ideally we want to use a hook, but have no idea which one to use.

Can you give us any direction?

Is there any documentation anywhere of what hooks are called, and when?

Thanks in advance

You can just look in the files, you'll see them once you get in there.
