@Cyron43 If it is of no benefit, I wouldn't worry about it. For those who need it, it will work, for those who don't, there are alternate solutions.
The modifiers are intended to be used with the KeyDown, so if you don't use that, it's nothing to worry about. You don't use it at all, I use it a lot, it's just the different ways people work and the different types of software they write.
I have done both app and game development for close to 36 years and in that time, I have had many instances where I need to press Shift then hold a key to do an action fast, or press Control then hold a key to do something slow. So because that relies on two keys being held, you never trigger a KeyUp event, so that event serves no purpose in that situation.
If I am solely doing a key-based app, that only registers key-presses, then I will only ever use KeyUp because it avoids repeats. It's all about being in the situation where a certain process is required and if you ever need a solution that requires keys being held, rather than pressed, you will then use KeyDown.
