That's the first time I've gotten that instead of a V. I didn't bother editing it because I thought it was amusing.

More often (but still rare), I'll end up with a † instead of t. As someone below mentioned, it appears to be (on Mac) opt+key.

I use a Razer Blackwidow something something mechanical keyboard, and it sits pretty tall. Only just now I figured out how I think this opt thing is happening. The side of my left hand appears to sometimes sit low enough that it may be bumping the opt key. Prior to this moment, the whole † thing had been a mystery to me :P.

Not OP, speculating. On a Mac option + v types a √, which is a fairly easy typo.

Yes, this seems to be what is happening. I now think that on rare occasions the side of my left hand may be brushing the opt key while I type. Until today, it has only been a very rare † instead of t. √ is a new one for me.

It is?
