DPR,
Computer keys?? That has the be the best idea I've ever heard for shoulder/collar bolts! I never would've thought of that!
And to think, I have a spare keyboard in my home office!
I agree about the furniture buffers. They look okay painted, but they scuff too easy, revealing the clear plastic beneath. They work okay, but not as good as machined aluminum ones or...computer keys! (I have GOT to try this next time!)
