no, I don’t think we need & more often than we need 1
and for accents, the canadian french qwerty keyboard handles them just fine; é (by far the most common accented letter) has its own key, all the other use dedicated dead keys. it works well!
and you can write accented uppercase letters using the CF qwerty, on azerty you need a combination with AltGr for that (because using just shift types the numbers…)
It's great in mobas where skills are universally referred to by their default binding on qwerty (since most layouts have qwer on those keys). So sometimes unaware french people talk about their a and z skills and everyone else is just confused
UK keyboards have the " and the @ symbols reversed from the US layout.
And we mix and match our units of measurement.
So
milk = liters.
Beer = pints.
Distance = miles (if driving).
Distance = km if running or cycling.
Distance = inches if penis
But why would you be hitting enter when you haven't hit ! yet? That would require you to skip !, to be typing at a high wpm but still be error prone, and for you to make three mistakes in a row and then for you to not immediately edit or delete and retype the message.
This takes low accuracy (so a typical hunt and peck user), high speed (so a usual touch typer), and a lack of technical knowledge, all rolled up with multiple failures. Nah, this didn't happen.
