I'm writing a scene right now that involves a ghost. And right as I'm writing the ghost's only line of dialogue, I press the CTRL key to underline the words -- and it pops off the keyboard. Ghosts are inside my laptop. I think I've been able to re-attach it, although it feels not-quite-attached. At least it's pretty much the least important key there is. On my previous laptop, a couple months before it was put out to pasture, the letters started popping off. Maybe it's the way I type. Although that one was 5 years old, this one's barely a year. So it seems way too early for my keyboard to start getting destroyed.
I don't know how to type, incidentally. I hunt and peck. Quickly, but with my 2 pointer fingers and that's pretty much it.
