(like, if I just hack in a paper clip that closes the circuit, then power starts coming out of the top connector?)
And then I need ground. So, second question.
You also said I could use the bottom connectors as ground. I've actually pried open a kindle and saw the ground connector which is right next to this slot, but wouldn't that break the live end of this two-pin short circuit? This is me not knowing enough of electronics asking. Or will the current just go harmlessly through the ground side of the switch?
Sorry about the noobness, I'm at that point in knowledge where I know enough to be a hazard, but not enough to be of use

Please ask technical questions in the Dev Corner forum. I do not want to get stomped on again for "talking tech" in this "general users" forum when I provide technical answers to technical questions.
Now that you asked this here, I will risk it again and give a useful technical answer: When you short the bottom pins, the combination is still grounded. One of them is an INPUT pin that normally floats high. Grounding it activates power to the top connector. That ground is shared by the serial Rx and Tx pins above it, and also used as the LED light power return path to ground. Try to not short your ground to the top Tx pin. Instead of a paperclip, there are posts here that show how to make a clip that fits into that slot, as part of a custom lighted cover.
