Ack! My shift key's popped off!

I've been noticing for the past few months that my three year-old (or is it four) Powerbook's right shift key has not been right. Last Sunday while at a coffee shop, it just popped right off. I thought it was as easy as putting it right back in like on the Apple keyboard for my iMac. I was wrong. It's more complicated than that. I tried as best as I could to put it right back in. It worked. Or so I thought.



This morning it again got loose and popped out. Any attempts to put it back in failed. I can see some plastic doohickeys on the underside have snapped off. I guess I have to admit to the fact that this key has no chance of ever going to be used again. Need to figure out a way to fix this.
