I own a MacBook Air 2013 and I recently broke my "comma" key.
I had to pull it out to clean underneath and I think I was a bit rough, so one of the hooks in the key cap broke. I put it back on and it seems to work but the key pops out often. My concern is not with the key cap, I'm worried about the hinge. How can I tell the hinge is not broken? How can I know if I didn't break it either?
