inaccurate typing with Logitech K310

I mentioned earlier that this KB might be the answer to destruction-by-sand in the desert southwest.

That still holds, but my typing accuracy had plummeted. Most maddening was my left hand shifting over and hitting CapsLock instead of a. Arggggh, WTF? Why am I making these mistakes?

It took me two months to notice there are no bumps to identify “home keys” (f and j); those keys are as flat as all the others. Just before writing this I cut two tiny squares of gorilla tape and stuck them on those keys. Problem solved. I might eventually use something more permanent like a tiny blob of gel superglue or something but for now I’m happy.
