Yes modifiers are a state, not a key. The kitty keyboard protocol does indeed send events for left and right modifier key press/releas as you can easily see for yourself by running

kitten show-key -m kitty

in a kitty terminal and pressing the left and right modifier keys.

> Yes modifiers are a state, not a key

So why are you talking about a key then??? Kitty doesn't support left/right modifiers unlike proper keybinding handling apps, the left/right presses for non-modifier keys aren't relevant

How would you bind LeftAlt-A to something different from RightAlt-A in Kitty?

[aumerle]

There is no such thing as a left or right modifier STATE in ANY application. All applications, including kitty track only CTRL, SHIFT, ALT, ETC modifier states. left and right alt and control are key events and can be bound in any application supporting the kitty keyboard protocol as key events. If some application tracks a left and right modifier state it has to do so manually using key press and release events, the OS does not supply it any such state.

You seem to be thoroughly confused about what is a modifier and what is a key. Left and right ctrl/alt/shift are KEYS not MODIFIERS. You can track whether they are held down or up by tracking their press and release events just like for any other key.

This rigid simplistic attitude is precisely why we can't have nice keyboard things and have been stuck in the same state of bad defaults for decades

The only differentiator for a modifier state is that it... modifies! Here is a wiki common sense definition

> In computing, a modifier key is a special key (or combination) on a computer keyboard that temporarily modifies the normal action of another key when pressed together

So your limitations don't make conceptual sense, not only can you have LShift vs RShift modifier state, but also you can have an F modifier state when you hold down the F key to modify the behavior of other keys

> OS does not supply it

Unless it does?

> VK_LSHIFT VK_RSHIFT VK_LCONTROL VK_RCONTROL VK_LMENU VK_RMENU These left- and right-distinguishing constants are available to an application only through the GetKeyboardState, SetKeyboardState, GetAsyncKeyState, GetKeyState, and MapVirtualKey functions.

ROFL you are saying that kitty the program that finally broke the keyboard logjam with terminals of preventing you from having nice things!! Good luck to you.

And lets apply some common sense to your common sense, follow up on it a little. If a modifier is defined by the fact that it modifies the actions of other keys, then left and right modifer keys modify the action in exactly the same way and thus are the same modifier. Common sense indeed.

And if you want to reference windows, a platform kitty does not support, here you go: https://developer.apple.com/documentation/appkit/nseventmodi...

no left and right modifier state on macOS. And neither does X11/Wayland have them, though I dont have a link handy, so I will just leave you with a couple of links to the documentation for cross platform toolkits instead:

https://doc.qt.io/qt-6/qt.html#KeyboardModifier-enum https://www.glfw.org/docs/latest/group__mods.html

And in case the common sense didnt make it past your mental barriers, a terminal keyboard protocol has to work on all platforms not just windows. The good lord alone knows what windows does, probably synthesizes that state based on press and release events.

I'm not saying that, it's something you've made up for your inner rofls.

> If a modifier is defined by the fact that it modifies the actions of other keys, then left and right modifer keys modify the action in exactly the same way and thus are the same modifier. Common sense indeed.

No, that's nonsense and factually wrong. Common sense is that a different modifier key is still a different modifier key even if the modification is the same. You have to do some logic twists not to make it so. Also, this is factually wrong: they don't modify the action in exactly the same way, that depends entirely on your config. In mine they act differently

> And if you want to reference windows, a platform kitty does not support, here you go:

But your overly confident overly broad statements weren't platform limited. So how are your links to the backward platforms / gui frameworks relevant? I've already acknowledged "state of bad defaults"

> a terminal keyboard protocol has to work on all platforms not just windows.

And if you turn your mental barrier off, it's pretty obvious how to make it work everywhere - you simply flag both left+right on getting the no-side flag info on a backward platform that doesnt differentiate. And only flag either left or right on a platform that does differentiate. Or differentiate it yourself by reading raw codes. So there are no good reasons to create yet another bad keyboard protocol when it works fine without blinders off

> The good lord alone knows what windows does, probably synthesizes that state based on press and release events.

Do tell me, what is the alternative magic of how Mac/Linux synthesize Shift state without press/release events?

Says you. And as you have abundantly demonstrated, you are a moron.

>No, that's nonsense and factually wrong. Common sense is that a different modifier key is still a different modifier key even if the modification is the same.

ROFL more idiotic assertions.

Nope my perfectly confident assertions were perfectly correct and shared by every framework under the sun. Because they are right. You coming up with nonsense use cases from under your overly small sized hat doesn't change that.

> And if you turn your mental barrier off, it's pretty obvious how to make it work everywhere - you simply flag both left+right on getting the no-side flag info on a backward platform that doesnt differentiate.

The good reason is that modifiers are state. Left and right modifier keys modify that state in exactly the same way. You WANTING them to work differently doesn't make it so. And you bloviating about how it's a bad protocol just makes you look like the moron you are, No terminal emulator developer is going to agree to implement a keyboard protocol that requires bypassing how the platform the terminal emulator runs on handles modifier keys. Because you want it to be so. What a joke. Grow up. Or actually dont, keep on ranting on internet forums about your pet demand, all the grown ups are just going to ignore you and/or laugh at you. Good bye and good luck.
