Do you hit alt+space at all? I accidentally discovered it just recently, hit it by accident, hit escape real fast, but then the mental picture registered in my head and I was like hmm, but couldn’t figure out what I hit. The software I use for work has all sorts of ctrls and alts in it, and soi resigned myself to having to stumble upon it again, which fortunately I did. It’s mainly a quick and easy calculator, you type some equation, and then you can have it automatically go to your clipboard.

This may just be a power toys thing, I have no idea, I use tools that are beyond my ability, whatever happens happens.
