It's funny, because some of my colleagues are thinking of switching the other way around, at least during video conferencing. They have to mute themselves to do a quick Google search, otherwise you have this annoying sound when you talk.
That's interesting. The etiquette where I work has sprung up to keep yourself muted unless you're the one talking, and if you're talking you're not typing, so it's less of an issue.
The etiquette is roughly similar, it's just that sometimes the person talking is also the one needing to get more info, e.g. open the relevant ticket or something. It's certainly not impossible to mute while they do the search, but apparently it's annoying enough that they have thought about changing the keyboard.
