My crappy trackball was acting up and I was irritable that day so I got mad, pounded it a bit, and the keyboard bounced off the desk and when I picked it up the F keystem had snapped, maybe when it hit the computer tower.
I have black on charcoal labeled keys but I don't care what I get. I have the keys arranged in default QWERTY layout. If you have one to spare that is profiled for the home row that's great.
I'll still eventually want the correct letter so I can have the bump on it.
