Help with making fanpost

I know this might sound dumb, but while trying to make a fanpost about a draft prospect I like, I closed the window that listed the keystrokes and editing tools, and I can't find how to open it back up. It said I would easily be able to open it again, which is why I closed it in the first place, but there is literally nothing I am seeing to click on to restore it. If someone could tell me how to find this window again, or even just post a list of all the keystrokes and editing tools, that would be great. Thank you!
