After three weeks of typing with just the under-key nubbin, my tab key is back to full functionality!
The new one is literally shinier – there’s not three years of heavy wear on it, or finger grease. PowerBookMedic.com didn’t overcharge me too much – $10.70 for the key and shipping. I saw much more ridiculous prices out there. They have a captive audience, so I guess they can get away with overcharging.
Chronos is whole again!
