Is there a real manual somewhere? Something that describes screen elements, etc.? Like when I'm typing something in the lower left corner next to the "keyboard" there's a funny shaped thing that I don't see on the controller anywhere. There's what appears to be an "L" in the thing but I don't see an "L" anywhere either. Also, in the upper right corner of the screen there is sometimes a "?" on what looks like a purple square. There are also indicators for messages, etc. I can find no way to access any of this stuff.
