Which button do I press to use Admin Actions Module? Please help!

By default it is the app menu key. The key between your right windows and right control keys.

What do you mean? What app menu key?

I don't have the menu/app key on my keyboard and it says use custom key 22 ingame if you don't have it but the custom keys only go to 20.

Any other way to open the menu?
