The people clamoring against the inclusion of biological outliers are operating under the false -and frankly poorly thought out- idea that sports are fair and that it’s only by training the hardest that you can and will achieve victory, shonen style.
Ultimately the only completely fair-ish competition is the one where you try to outdo your previous best performance and beat your own records. Otherwise, there are so many other variables you’d have to correct for to level the playing field (and testosterone levels is not a great pick for that anyway) that you might as well have single athlete categories.
It’s true they would probably be more useful to the average keyboard user than say the scroll lock key, or the fucking copilot key. But to be really useful, they would have to be easily accessible without moving you bands, or else it’d just be faster to use a shortcut. Keyboards with macro keys do exist so maybe get one and map them to CTRL+C/V
