> you can absolutely ctrl+c before 100 more ms are up

Not gonna believe that without empirical evidence.

I think they are talking about times where you realize a mistake as you are making it as opposed to hindsight, given that 100ms seems pretty reasonable.

"seems pretty reasonable" is not evidence.

This is exactly what I'm trying to say. The actions are underway by muscles (or _just_ completed) and the brain catches something's off and so ctrl+c is queued.

I am not sure, have you read it properly? The scenario is that you are pushing enter, halfway change your mind, and your are switching to ctrl+c. So it is not a reaction time, but an enter to ctrl+c scenario.

Regarding reaction time, below 120ms (on a computer, in a browser(!)) is consistently achievable, e.g. this random yt video https://youtu.be/EH0Kh7WQM7w?t=45 .

For some reason, I can't find more official reaction time measurements (by scientists, on world champion athletes, e-athletes), which is surprising.

That scenario seems to me fishy to begin with, is that something that actually happens, or just something people imagine? How would it work that you "change your mind halfway through" and somehow cannot stop your finger from pressing enter, but can move them over and hit ctrl-c in a ridiculously short time window?

> So it is not a reaction time, but an enter to ctrl+c scenario.

At minimum, if we ignore the whole "changing your mind" thing. And for comparison: the world record for typing speed (over 15 seconds and without using any modifier keys) is around 300wpm, which translates to one keypress every 40ms - you really think 100ms to press two keys is something "you can absolutely" do? I'd believe that some* people could sometimes do it, but certainly not just anyone.

That'd be interesting, but I don't know how to prove that I'm not just "pretending" to make typos and correcting them instantly ?
