I spilled milk on my keyboard mildly... I tried tipping my keyboard upside down, and surprisingly, it drained a lot of it out. Eventually, my right CTRL key became stuck, so I removed it, and some surrounding keys, and eventually got it working fine again... I am very picky. While putting my right SHIFT key back in, after noticing there's a little metal rod that's shaped like a staple, and in fact TWO rubber "buttons" because the shift key is horizontally longer than a normal key... Ever since I took it out, I don't think I really know HOW to put it back in... It just never seemed to be working right. Currently, the problem is I have to hit the RIGHT side of the shift key in order for it to register... the right button underneath it. I feel like a noob, but oh well! I don't think the shift key is pressing down as "one", basically. It will only hit one button underneath it if I press too far to the left... they shouldn't do that.
Hopefully I explained it well enough.
