Yeah, it's so hard to find that information that it tells you how to turn it on in the beginning. It's so hard that Fallout 3 was the exact same way. It's so hard, that it's in the manual. That's how hard it is to find information on how to turn on your Pipboy light.

Furthermore, how did you "make" the default pipboy button tab when it was already tab to begin with?
None of this adds up. You begin by talking about the light and how people who played Fallout 3 would be familar with pressing Tab for it, when Fallout 3 you had to hold it down too. It was the exact same setup. If you played FO3, then you know this. The game specifically tells you how to do it, and the manual tells you how to do it. Why? Why did you post that this is hard information to find when it's literally everywhere?
It turns out that I'm not as smart as you. Your intellect is like a bright, shining star in the sky. Like a brilliant detective you've pierced the black veil of mystery and, like a roaming searchlight, have illuminated those dark corners for us all to behold! Wow! I bet the women and men swarm all over you because you're so smart. I bet they ask you to predict the future for them, too. Jeez, I just wish I was as smart as you!
One day, if I try really hard at school, go the best college, and become an industry leader in my field, then and only then can I see myself booting up my computer, logging into a message board, and teaching all the little dweebs out there that I'm the biggest jerk you will ever meet. I will use that intellect like a weapon for my own amusemant, and everyone will tremble at my feet. "What will he say next," they'll say as they tremble in fear, "his intellect burns my eyes!"
I will roam that message board like I was its King. I will hand down judgment and spew my filthy opinions all over that message board in the pitiful attempt to make myself accepted, or perhaps make friends. Man, how cool I'll be once I'm as smart as Pyris! One day I'll be able to prove how much of a jerker I am, and make it look as easy as him. Thank you, Pyris, you're a very inspiring fellow!
Your comment really helped me a lot, and added a lot to this discussion. I can't wait to see what knowledge you'll drop on us all next. Please, bless us with another jem!
