Darn, I was going to suggest Roomnesia.

The word you’re looking for is fenderberg.
You’re welcome.
I’ve played guitar with a flatpick and my remaining fingers for almost thirty years. This year, I switched to using a thumbpick. This means that my index finger has to catch up with my remaining fingers in dexterity. As a result, I sometimes have to focus on not letting the index finger loaf and let the thumb and other fingers do the work. I sometimes tell people that I suffer from ‘lazy-finger’ syndrome, or amblydigitosis. (I’m not sure if I’ve constructed it correctly – IANAD, and my high school Latin is rusty).
Googlamnesia–Forgetting what you were going to search when the Google page comes up.
Ah! That’s it! Thanks much. I hit a fenderberg so big once that it broke the cowling in the front of my car. That was a titanic fenderberg.
Let’s master one of my favorite old words first.
