Hello,
I’m making my own textbox for more complex algebra input (using Ian Harrigan’s hx-mathml renderer) and it’s almost done, but there’s one big issue I’m encountering – the numpad reports the same keycodes as
some letters. specifically:
1->a
2->b
3->c
and so on.
I’m going to start investigating this a little bit but before I do, has anyone found a workaround for this? There must be something in the event that differentiates the two inputs.
Update: seems there’s a keyLocation variable in KeyboardEvent, but it doesnt report if it’s coming from numpad or not? It just reports 0.
Could you try stage.window.onKeyDown.add (function (key) { trace (key); }); and see if the Lime key codes are different, or the same?
They are the same–97 for 1 and a, 98 for 2 and b, and so on.
Interesting, we are currently SDL key codes directly
https://wiki.libsdl.org/SDL_Keycode
I see different codes in here for keypad numerals as opposed to other keys.
We do mapping on the OpenFL side in order to convert to Flash-style key codes, but the Lime events should work 
Let me try here and see what I get
I’m trying the following code (sorry my earlier example wasn’t quite correct):
stage.window.onKeyDown.add (function (keyCode, modifier) {
trace (keyCode);
});
I get key codes such as 1073741913 or 1073741920 when I press the keypad, while standard keys give me 97 or 115 (etc)
Perhaps the issue is in the OpenFL layer, then, in how keypad numerals are treated.
an important part of this (that i definitely, definitely shouldve mentioned from the start, my apologies): my target is html5. on html5 I’m running the exact same code and getting the same keyCodes for numpad and letters.
Oh, haha, that is important 
I just ran a test, and got these results on Flash:

I am stuck with Openfl 3.6.1 and Lime 2.9.1: is it possible to apply the fix from the new Lime to the old one? I hope to switch to the new versions soon, but I am in a hurry to fix this bug, because clients need to interact with dynamic texts to insert numbers, and getting letter codes instead of number codes is a big problem, and I can’t distinguish between numpad keycodes and letter ones.
EDIT: I replaced the old HTML5Application.hx in HaxeToolkit\haxe\lib\lime\2,9,1\lime_backend\html5 with the new version and now the numpad seems to work correctly. Is it sufficient?
